Characteristics of PWM inverter-driven hysteresis motor with short-duration overexcitation

摘要

This paper presents the characteristics of PWM inverter-driven hysteresis motor with short-duration overexcitation. When voltage changes to a step form etc., the change of the rotational speed of hysteresis motor and the change of input current are clarified especially. It is shown clearly that it is good to make a voltage variable pattern into a trapezoidal wave from an experimental result.
