    • PURPOSE: To provide a start control method of a synchronous motor which has excellent start performance and can put the motor into a commutation mode in a short time. CONSTITUTION: An AC current with a prescribed frequency is applied to a field winding 81 of a synchronous motor 8 by an inverter 91 to start the synchronous motor 8. The terminal voltage of the field winding 81 of the synchronous motor 8 at the starting time is detected. A voltage wave component according to the AC current given by the inverter is deducted from the detected voltage to correct the waveform in order to recognize a voltage wave component produced by a counter electromotive force (110). After the corrected waveform is integrated (111) and converted into a square waveform (111), the phase difference between the square waveform and an output of a 120° applied current waveform generating circuit 102 is detected by a phase difference detection circuit and is fed back.
    • 目的:提供一种具有出色启动性能的同步电机的起动控制方法,可以在短时间内将电机置于换向模式。 构成:通过逆变器91将具有规定频率的交流电流施加到同步电动机8的励磁绕组81以起动同步电动机8.同步电动机8的励磁绕组81的起动时的端子电压为 检测。 从检测电压中扣除根据逆变器给出的交流电流的电压波分量,以校正波形,以便识别由反电动势(110)产生的电压波分量。 在校正波形被积分(111)并转换成方波(111)之后,方波和120°加电流波形发生电路102的输出之间的相位差由相位差检测电路检测,并被馈送 背部。
