Abstract: An electric power quality analyzer was used to carry out test for the motor variable frequency speed regulation device of air compressor units to search the factors impacting on motor operation efficiency and to analyze three-phase synchronous motor operation parameters of variable frequency speed regulation. Test results show that adopting pulse width modulation (PWM)variable frequency speed regulation is fast in speed regulation, good in dynamic characteristics and high in input power factor, to achieve motor stable soft start, reliable operation and energy saving technology reform.
