Nidec Introduces SynRA Motor

June 3, 2022
Motor uses synchronous technology for energy savings.

Nidec Motor Corp. introduces SynRA, an innovative, patent-pending synchronous motor. When paired with the ID300 Perfectspeed integrated drive, the new motor offers one of the highest efficiencies available for today’s industrial and commercial pumping and HVAC equipment, according to Nidec – with ratings at IE 4 and IE 5. In addition to energy savings, the new technology offers the advantage of easy motor replacement, without having to install an entirely new system and controls.

SynRA provides the operating benefit of a pure synchronous reluctance motor, and suitability benefit from a simple volts/hz drive. The unique design gives the freedom to replace components individually instead of the entire system, leading to a lower cost of maintenance. The product’s smart technology results in less wear and tear on blower or pump systems by matching application demands with variable speed.

The synchronous reluctance rotor with an aluminum cage design is magnet-free, allowing for easy programming and compatibility with existing variable frequency drives (VFDs). The SynRA motor is also available already fully integrated with Nidec’s ID300 PerfectSpeed.

Applications include:

  • Inverter driven variable torque (VT) loads (Pumps, Fans, Blowers, etc.)
  • OEM constant pressure booster pump systems
  • OEM variable speed hydronic pump systems
  • Super premium replacement VFD motors
