    The SPM can be applied as part of a complete synchronous motor controller. This consists of four parts. A main device switches the motor on and off the power system. Multifunction digital relays (such as the GE Power Management 469 Motor Management Relay) provide stator protection. DC field protection and control are provided by the SPM.
