This 3.3V family has devices that include a 4-megabit, a 2-megabit, a 1-megabit, and a 512-kilobit PROM. In addition to that, these PROMs provide a method that’s fairly easy to use and cost-effective for reprogramming and storing Xilinx FPGA configuration bitstreams.

This FPGA has two modes: Master Serial and Master SelectMAP. Each mode has its own sub-mode: the Slave Serial Mode and the Slave Parallel or Slave SelectMAP Mode.

The Master Serial mode allows it to generate a configuration clock. This clock is what drives the PROM. After CE and OE are enabled, data from the PROM DATA (D0) pin connected to the FPGA DIN pin is available for a short period of time. Each rising clock edge signals new data being made available for a short period of time. In the Slave Serial mode, an external cock will be what clocks the PROM and FPGA.

The Master SelectMAP mode also results in a configuration clock driving the PROM to be generated. New data also becomes available on the PROM’s DATA (D0-D7) pins for a short access time after CE and OE are enabled. After the rising edge of the CCLK, the data is then clocked into the FPGA. In Slave Parallel or Slave SelectMAP mode, an external oscillator will bear the responsibility of generating a configuration clock that drives the PROM and FPGA. In this mode, a free-running oscillator can be used.

The xilinx XC18V04VQ44C also allows multiple devices to be cascaded by driving the CE input of the device using the CEO output. The inputs clocked in and the output of DATA from all PROMs found in the chain are all interconnected.

The in-system programmable PROMs of the device can also be programmed individually. Alternatively, you can chain together two or more and program them in-system using the standard 4-pin JTAG protocol. This feature is useful because it allows for quick and efficient design iterations while at the same time eliminating any unnecessary package handling or socketing of devices.

Additionally, the Xilinx development system provides the programming data sequence to its users using either of the following: Xilinx iMPACT software and a download cable, a third-party JTAG development system, a JTAG-compatible board tester, or a simple microprocessor interface that emulates the JTAG instruction sequence.

Additionally, the Xilinx XC18V04VQ44C has dual configuration modes. Its serial configuration can go up to 33 MHz while its parallel configuration mode can reach 264 Mb/s at 33 MHz.

The I/OS on each reprogrammable PROM found in the Xilinx XC18V04VQ44C are also fully 5V tolerant, despite the core power supply being only 3.3V. This then eliminates any risk or damage that could be caused by connecting the 5V CMOS signals directly to the PROM inputs.

The device itself has a density of 4 Mbit with an operating supply voltage and an output capability of 3.3V. But it’s also worth noting that the Xilinx XC18V04VQ44C has no radiation hardening so you should take extra precautions from potentially exposing it to radiation.

Introduction to Motors

Motors are electro-mechanical devices that convert electrical energy into mechanical energy. They come in a variety of types depending on their construction, working principle, and applications. The two most common types of motors used in industrial and automation applications are servo motors and stepper motors.

Both servo and stepper motors provide precise motion control, but they have some key differences in their design and operation. This article will compare servo and stepper motors in detail in terms of their construction, working principle, performance characteristics, applications, advantages and disadvantages.

Overview of Servo Motors

A servo motor is a rotary or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servo motors.

Servo Motor

The key components of a servo motor are:

• Motor – Provides the motive force for the actuator. Common motor types used in servo systems include DC brushed, brushless DC, AC induction, and AC synchronous motors.
• Gearbox – Used to increase the torque output from the motor. Often equipped with high ratio gears to allow slower motor speeds but higher torque.
• Encoder – Sensor that provides position and speed feedback to the controller. Resolvers and optical encoders are commonly used.
• Controller – Compares the actual position to the desired position and calculates the required drive signals for the motor. Uses PID control algorithms.
• Potentiometer – Measures position of output shaft and provides position feedback to controller.

The controller commands the motor to rotate to the desired position as fast as possible. Once the motor reaches the desired position, it stops. If an external force pushes against the motor, it will hold the position due to the servo control system.

Servo motors provide closed-loop control with high accuracy and fast response times. As a result, they are ideal for applications requiring precise position control such as robotics, CNC machines, pick-and-place equipment, and other factory automation machinery.

Overview of Stepper Motors

A stepper motor is a type of brushless DC electric motor that divides a full rotation into a number of equal steps. Unlike servo motors which rotate continuously, stepper motors move in discrete increments or steps.

Stepper Motor

The key components of a stepper motor are:

• Stator – The stationary part consisting of stacked steel laminations with winding coils around the poles.
• Rotor – The output shaft along with a magnetized part that interacts with the magnetic field from the stator coils.
• Driver – The driver energizes the motor coils in the proper sequence to cause rotation. Open-loop control.

Stepper motors operate on the principle of electromagnetism. The motor coils are energized in a specific sequence, creating magnetic poles that attract and repel the permanent magnets on the rotor. This causes the rotor to turn a precise angle or “step” each time a coil set is energized.

By controlling the sequence and coils energized, the motor can be turned in precise increments. No closed loop feedback is required, though often an encoder can provide position verification.

Stepper motors provide excellent low speed torque and position control without requiring encoders or servo control. They are commonly used in 3D printers, CNC machines, plotters, and other applications requiring high precision motion.

Construction and Design

Both servo and stepper motors have unique construction characteristics optimized for their particular applications and operating principles.

Servo Motor Construction

The construction and design of a servo motor can vary greatly depending on the motor power, torque, speed, and accuracy requirements. But in general servo motors consist of the following components:

• Stator – Usually made up of laminated steel with winding coils around the stator poles. The number of pole pairs determines the number of magnetic poles.
• Rotor – Made of permanent magnets alternating in polarity around a rotor shaft or core. Often high energy rare earth magnets are used.
• Shaft – Heavy duty output shaft with high stiffness for minimal deflection under load. Supported by precision ball bearings.
• Housing – Cast iron or steel housing provides structural support and protects internal components. Often thermally conductive to aid cooling.
• Feedback device – Resolvers, encoders or potentiometers are attached to monitor rotor position.
• Gearbox – High ratio gearboxes are often integrated to increase torque capacity. Spur, planetary, and harmonic gears are commonly used.

The stator, rotor, bearings, and housing make up the actual motor section. The feedback device and gearbox augment the motor capabilities for high performance servo applications.

Stepper Motor Construction

Stepper motors have a relatively simple electromechanical construction optimized for open-loop positioning control. The basic components include:

• Stator – Made up of stacked steel laminations with winding coils around the poles. The number of phases determines the number of coil sets.
• Rotor – A permanent magnet with alternating north and south poles arranged radially around a central shaft.
• Shaft – Usually an integrated shaft machined as part of the rotor. Supported by bushings or ball bearings.
• Housing – Lightweight aluminum or thermoplastic housings enclose the stator and rotor. Air or liquid cooling may be integrated.
• Bearings – High speed sleeve bearings, bushings or ball bearings support the rotor shaft.

Stepper motors do not require an encoder or gearbox for most applications. The simple stator and rotor design allows rapid manufacturing at low cost.

Comparison of Construction

Comparison	Servo Motor	Stepper Motor
Stator design	Laminated steel with concentrated windings	Stacked laminations with distributed windings
Rotor design	Salient pole or permanent magnet	Permanent magnet
Housing	Heavy cast iron or steel	Light aluminum or plastic
Bearings	High precision ball bearings	Bushings, sleeve or basic ball bearings
Feedback device	Encoder, resolver or potentiometer	Often none, sometimes encoder
Gearbox	Often integral high-ratio gearbox	Rarely used

In summary, servo motors have a robust stator, rotor and housing designed for high torque, speed and continuous duty operation. Stepper motors use lightweight materials and simple construction aimed at low cost and open-loop control.

Working Principle

While both servo and stepper motors produce rotational motion, their internal operating principle and control methods differ significantly.

Servo Motor Working Principle

Servo motors operate on the basis of a closed-loop control system. A controller provides a drive signal to the servo that is proportional to the difference between the commanded position and actual position.

Servo Motor Working Principle

The working principle involves:

• An input command to the controller indicating the desired position. This is compared to the position feedback.
• Error between actual and desired position is calculated. The controller sends a proportional drive signal to the servo amplifier.
• Motor is driven proportionally faster or slower to minimize position error.
• Encoder or resolver provides continuous position feedback to complete the control loop.

This closed loop control allows a servo motor to quickly and precisely rotate to a commanded angular position. Servo motors use PID control algorithms to optimize the dynamic response.

Stepper Motor Working Principle

Stepper motors operate on the principle of electromagnetism and discrete stepping of the rotor. Rotation is achieved by energizing coil windings in a specific sequence.

The stepper motor working principle:

• Applying current to a motor coil creates an electromagnetic pole. Opposite poles attract, similar poles repel.
• Alternating current to the motor coils moves the rotor. As the rotor teeth align with the energized stator pole, they lock in position.
• The driver sequentially energizes the motor coils to rotate the rotor in increments or steps. No closed loop control is used.
• Step angle is determined by rotor construction. Number of steps per revolution depends on step angle.

The open loop stepping operation allows the motor to move in controlled discrete increments without requiring a position sensor.

Comparison of Working Principles

Comparison	Servo Motor	Stepper Motor
Control method	Closed loop PID control	Open loop stepping
Feedback device	Encoder or resolver	Not required
Accuracy	Very high with closed loop control	Limited by step resolution
Speed	Wide speed range with rapid acceleration	Typically lower speed operation
Torque	High and continuous torque capability	High holding torque, lower power torque

In summary, servo motors use closed loop control for high accuracy while stepper motors operate open loop in discrete steps. Servo systems are more complex but offer better dynamic performance.

Performance Characteristics

The design and operating principles of servo and stepper motors impart distinct performance characteristics.

Servo Motor Performance Metrics

Key performance characteristics of servo motors include:

• Speed – Servo motors can operate over a wide speed range, often exceeding 6000 rpm for brushless servo motors. Rapid acceleration and deceleration is possible.
• Torque – Servo motors produce high torque, especially at lower speeds. Peak torque ranges from 10 Nm to over 1000 Nm depending on motor size.
• Power – Motor output power ranges from under 100 Watts to over 15 kW for large industrial servos. Power density is high.
• Accuracy – Position accuracy is very high, reaching 0.01 degree or better with high resolution encoders. Helped by tuned PID control gains.
• Repeatability – Positional repeatability is excellent, with consistent positioning under 0.01 degree. Benefits from closed loop control.

High torque density, acceleration, accuracy and repeatability make servo motors well suited for demanding automation applications. Advanced control algorithms allow optimized motion.

Stepper Motor Performance Metrics

The performance characteristics of a stepper motor include:

• Speed – Maximum speed ranges from 100 to 2000 RPM. Higher speeds require reduced torque and incremental microstepping.
• Torque – Stepper motors have very high holding torque but weaker power torque at higher speeds. Holding torque can exceed 3 Nm for small motors.
• Power – Typical motor power output ranges from below 100 Watts up to around 750 Watts. High speed operation results in lower power.
• Accuracy – Positioning accuracy depends on stepper resolution. Full step resolution is typically 1.8 degrees. Microstepping divides steps further.
• Repeatability – Excellent repeatability thanks to inherent step resolution. Positional error is limited to less than one step.

Stepper motors excel at slow speed, high precision positioning applications. Their relatively simple construction provides robustness at low cost.

Comparison of Performance Metrics

Comparison	Servo Motor	Stepper Motor
Speed range	Very wide, thousands of RPM	Narrow, typically below 2000 RPM
Torque density	Very high	High holding torque, lower running torque
Power output	Up to 15 kW+	Typically below 750 Watts
Accuracy	0.01 degree or better	1.8 degrees full step, higher with microstepping
Repeatability	Excellent, less than 0.01 degree	Very good, limited to step resolution

In summary, servo motors are designed for high speed and power operation with very high accuracy. Steppers trade off speed and power for high precision motion in an open loop control system.
