  • Page 7: Overview

    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 Mul- tilin 469 Motor Management Relay) provide stator protection. DC field protection and control are provided by the SPM.
