Nidec/U.S. MOTORS New SynRA Motor

As energy costs climb, the need for the highest level of energy-efficient pumping equipment has never been more critical. Nidec Motor Corp. has responded to that demand by introducing 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 – with ratings at IE 4 and IE 5. 

Nidec U.S. MOTORS SynRA with Perfectspeed- Integrated Motor and Drive.

In addition to significant energy savings, this new technology from Nidec’s U.S. MOTORS brand offers the advantage of easy motor replacement, without having to install an entirely new system and controls, saving time and money.  

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 design of the SynRA motor itself is made with ease in mind. 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
