MICROPROCESSOR SPEED CONTROLLER

摘要

An AC Motor Speed Controller (Figure 11) utilizes a Microprocessor programmed to control the Speed, Torque and Horsepower of an AC motor. The controller allows the speed of the motor to adjust to the desired level and is calibrated to develop the desired torque, either automatically through load feedback or through a predetermined or preset level. The controller also allows for excessive torque to be developed under starting and acceleration conditions while providing for controlled deceleration with proportional braking of the inertia load. Utilizing a single microprocessor results in a simple low cost controller.
