Inductance measuring device and measuring method for synchronous motor
摘要:
[Problem]For measuring the inductance of a synchronous motor, a high-speed and convenient inductance measuring device for a synchronous motor is provided.[Solution]A three-phase high-frequency rotation voltage is applied to a synchronous motor, thereby calculating the inductance from the same frequency component as that of the high-frequency voltage included in a motor current.
