摘要： A compensating system for compensating a cogging torque of a motor includes a speed measuring apparatus, a moment of inertia measuring apparatus, a rotor position sensor, a processor, a plurality of band-pass filters, and a current control apparatus. The processor receives a speed, a moment of inertia, and a rotor position of the motor, to determine the cogging torque of the motor. Each band-pass filter is arranged with a different frequency to filter different frequencies of waveforms of the cogging torque. The processor determines a Fourier transformation of the cogging torque according to a number of Fourier coefficients from the band-pass filters, a cogging torque at a preset rotor position, and a cogging current according to the Fourier transformation of the cogging torque. The current control apparatus outputs a current opposite to the cogging current, to compensate the cogging torque of the motor.

摘要： A device for controlling an induction motor includes a voltage/frequency controller, a pulse width modulation controller, and a converter. The voltage/frequency controller receives a controlling frequency, and outputs a controlling voltage corresponding to the controlling frequency. The pulse width modulation controller receives the controlling voltage and the controlling frequency, and generates PWM signals according to the controlling voltage and the controlling frequency. The converter receives the PWM signals, and controls the induction motor according to the PWM signals. There is a predetermined relationship between the controlling voltage and the controlling frequency stored in the voltage/frequency controller. The controlling voltage is greater than zero in response to the controlling frequency being zero, and increasing the controlling frequency increases the controlling voltage as in the predetermined relationship.
