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.
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.
