SynRA ODP SynRA Unimount 

SynRA™- super premium synchronous motors, made easy! The SynRA variable frequency motor provides the starting benefit of an induction motor, the operating benefit of a pure synchronous reluctance motor, and suitability benefit from the simple volts/hz drive. This market-leading product gives higher efficiency and power density without risking components. A unique design gives the freedom to replace components individually instead of the entire system - leading to a lower cost of maintenance. Smart Building Technology included gives less wear and tear on pump systems by preventing over-exertion and more speed than necessary to meet application demand.

The design of the SynRA motor itself is made with ease in mind. The synchronous reluctance rotor with an aluminum cage design has an absence of magnets to allow for easy programming and compatibility with existing Variable Frequency Drives (VFDs) or simple VFDs from U.S. MOTORS.
