Method and system for motor oscillatory state detection

Image Number 9 for United States Patent #7902777.

Method and system for motor oscillatory state detection. According to various embodiments, the present invention presents a method for determining whether a motor is in an oscillatory state. The method includes powering up a motor for a period of time and then monitoring the movement of the motor during a period after the power if turned off. Based on the movement of the motor and/or impeller during a time period after the power is turned off, whether the motor is in an oscillatory state is determined. The method also includes initiating a process for handle error if the motor is in the oscillation state.
