Abstract: A system for controlling a plurality of motors includes: a variable frequency drive (VFD) configured to control at least one property of the motors, the VFD having a current interruption rating that is greater than a continuous current rating of all of the plurality of motors combined; a bus electrically connected to the VFD; and a plurality of protection modules, each protection module including: a motor overload device electrically connected to a particular one of the plurality of motors; and a switching relay in series with the motor overload device, the switching relay configured to connect the protection module to and disconnect the protection module from the bus. A state of the switching relay determines whether the protection module is electrically connected to the bus, the VFD is configured to control the state of the switching relay, and the switching relay has a current interruption rating that is less than the continuous current rating of the particular one of the plurality of motors.

Abstract: A motor driver control system is configured for connection to a plurality of motors, the motor control system includes a motor driver command module, and the motor driver command module is configured to: access information related to one or more operating metrics of the plurality of motors; analyze the information to determine whether a maintenance condition exists in any of the plurality of motors; and if a maintenance condition exists in any of the plurality of motors: prevent electrical power from reaching any of the plurality of motors, identify which one or more of the plurality of motors has the maintenance condition, disconnect the one or more identified motors from the motor driver control system, and restore electrical power to all of the plurality of motors other than the identified motors after disconnecting the one or more identified motors.
