GE / Alstom SPM Synchronous Motor Protection System

SPM Synchronous Motor Protection Relay : GE?s motor protection systems use advanced thermal modeling to provide optimized protection and ensure maximum process uptime. Our highly skilled engineers and technicians understand motor protection and the various scenarios that can cause damage to motors. They apply their knowledge to the design and manufacture of some of the most advanced protection relays and systems in the world.
GE?s SPM provides critical protection, synchronization and control for collector-ring or brush type sunchronous motors. The SPM?s control functions for starting the synchronous motor include accurate sensing of the motor speed and rotor angle ensuring proper operation and health of the motor.

The SPM controls starting, synchronizing, and protection of
? collector-ring or brushless type synchronous motors.
? New Harsh Environment Conformal Coating option.
