  • Microprocessor speed controller
    Patent number: 4843297
    Abstract: An AC Motor Speed Controller used to control the Speed, Torque and Horsepower of an AC motor. It allows the speed of the motor to be adjusted to the desired level and is calibrated to develop the desired torque, either automatically through load feedback or through a predetermined or preset level. It 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.

  • Motor control system
    Patent number: 4465961
    Abstract: A motor control system for AC motors utilizing an inverter which is switched to provide pulsewidth modulated DC voltage to be applied to the motor in phase sequence. The pulsewidth modulation is a function of an input reference signal, a signal dependent on motor current and a boost signal operative at low speeds. The motor voltage is continuously regulated as a function of load to provide the necessary power to drive the load.

  • Motor control system
    Patent number: 4334182
    Abstract: A motor speed control system (controller) for controlling the speed of an AC motor. The invention provides sufficient voltage at low motor speeds to overcome the high resistance of fractional H.P. motors, which effects low speed operation, i.e., the ability to provide constant load torque. With the present invention an output frequency voltage offset is provided in a non-linear fashion so that desired load torque is developed over the entire speed range of the control system.
