VARIABLE SPEED MOTOR CONTROL |
摘要 |
A motor control for a multi-phase compressor motor. The control responds to a speed control signal to cause the motor speed to track the speed control signal without changing the motor torque. This is accomplished by pulse width modulating motor speed signals in a sinusoidal manner to maintain the volts/hertz applied to the motor constant regardless of motor speed. <IMAGE> |
