Abstract


Provision of electromechanical compatibility of asynchronous drive is considered. A computer drive model has been developed to investigate electromechanical processes in systems with PWM-inventors and asynchronous motors. Model calculations show that continuous change in the reference voltage frequency enables a multiple decrease of the amplitude of higher harmonics and electromagnetic torque with constant distortion factor. Vibrations of the electric drive may be decreased due to the reduced amplitudes of the torque harmonics. Motor losses change insignificantly. Variation of the reference voltage frequency within the given range should not to be implemented with frequency of motor supply currents.
