A motor control subsystem runs the motor in accordance with a command specifying a speed or torque. A vibration sensor, such as a three-axis accelerometer, senses a vibration of the electric motor, or, alternatively, software indirectly detects the vibration based on phase or torque ripple.

A control element receives data regarding the vibration, determines whether the vibration exceeds a pre-determined limit, and if so, takes action to reduce the vibration of the electric motor below the pre-determined limit. Such action may involve slowing or stopping the motor, thereby avoiding damage, increasing reliability, and reducing cost.
