摘要： A monitoring system is disclosed for identifying an operating state of a motor, the system comprising: a speed sensor for determining a speed of a motor and providing a speed signal as a function of time in response thereto, and a processor configured to identify a symmetric and/or an asymmetric oscillation of the speed signal as a function of time.
