Insulated Gate Transistors Simplify AC Motor Speed Control (PDF)

An IGT�s few input requirements and low On-state resistance simplify drive circuitry and increase power efficiency in motorcontrol applications. The voltage-controlled, MOSFET-like
input and transfer characteristics of the insulated-gate transistor (IGT) (see EDN, September 29, 1983, pg 153 for IGT details) simplify power-control circuitry when compared with bipolar devices.

AC DC motor speed control with MOSFETs (PDF 91p)

Controlling an a.c. induction motor by the technique of sinewave-weighted pulse-width modulation (PWM)switching gives the benefits of smooth torque at low speeds,
and also complete speed control fromzero up to the nominal rated speed of the motor, with only small additional motor losses.

DC MOTOR CONTROL SYSTEMS FOR ROBOT APPLICATIONS (PDF)

The output of the plant does not affect the input. (No feedback)
„Less common today than closed loop
control systems.

Controlling 3 Phase AC Induction Motors Using the PIC18F4431 (PDF)

Previous Microchip authors (Parekh and Yedamale) have described the implementation of a 3-phase AC induction motor (ACIM) control with PICmicro� devices.

DC Motor Control Tips n Tricks (PDF 36p)

All motors require drive circuitry which controls the current flow through the motor windings. This
includes the direction and magnitude of the current flow. The simplest type of motor, to drive, is the Brushed DC motor.

Determining MOSFET Driver Needs for Motor Drive Applications (PDF)

Electronic motor control for various types of motors represents one of the main applications for MOSFET drivers today. This application note discusses some of the fundamental concepts needed to obtain the proper MOSFET driver for your application.

HOW TO DRIVE DC MOTORS WITH SMART POWER ICS (PDF)

There are many ways to control DC motors. Open-loop current control acts directly on torque and thus protects the electronics, the motor and the load. Open-loop variable voltage control makes
sense if the motor and electronics are not overloaded when the motor stalls. Open-loop variable voltage control with a current limiting circuit constitutes the simplest way of varying speed.

Bi directional Control Of Motors And The H Bridge

It would be useful to be able to run a motor in either direction. That's simple with a motor of the type that's been used in the experiments thus far. Reverse the DC power connections on such a motor and its shaft will rotate in the opposite direction. One way to control direction is to use switches arranged in the following manner:

FREQUENCY CONTROLLED AC MOTOR DRIVE (PDF)

The squirrel cage induction motor is the electrical motor type most widely used in industry. This leading position results mainly from certain excellent features of
the squirrel cage motor such as:
� Uncomplicated, rugged construction. For the user this means low initial cost and high reliability.
� Good efficiency coupled with low maintenance costs resulting in low overall operating costs.
