MONITORING SYNCHRONIZATION OF A MOTOR USING STATOR CURRENT MEASUREMENTS

摘要

Monitoring synchronization of an electric motor using current signals from power supplied to the motor is disclosed herein. The current signals may be used to calculate representative current values which may be used to calculate a rotational frequency of the rotor of the motor. The rotational frequency may be used to determine synchronization, such as slip. Monitoring may be during startup of a synchronous motor in induction mode. Upon reaching a predetermined synchronization threshold, the motor may be configured from induction mode to synchronous mode.
