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. |
