DC MOTOR CONTROL SYSTEMS FOR ROBOT APPLICATIONS (PDF)

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

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.

DRIVING DC MOTORS (PDF)

Driving DC motors with integrated circuits seems at first to be rather simple. Yet by analyzing the actual application it is possible to see if there exist conditions causing stresses to the IC during operation which in the end can cause failure. With proper design and analysis in critical applications it is possible to avoid conditions which lead to IC damage.

MOSFET IGBT DRIVERS THEORY AND APPLICATIONS (PDF)

Modern Power Electronics makes generous use of MOSFETs and IGBTs in most applications and, if the present trend is any indication, the future will see more and more
applications making use of MOSFETs and IGBTs.

Configuring a Motion Control System

This document provides a general introduction to motion control and is designed to help you get started with your own motion control system.

Motor Control Sensor Feedback Circuits (PDF)

Sensors are a critical component in a motor control system. They are used to sense the current,position, speed and direction of the rotating motor. Recent advancements in sensor technology have improved the accuracy and reliability of sensors, while reducing the cost.
