SynRA – Synchronous Reluctance Rotor with Aluminum Cage     
Kyle Mertens, Product Manager, Nidec Motor Corp.

Michael Detmering, Manager of Project Management, Nidec Motor Corp.

The SynRA, a new synchronous reluctance motor technology utilizing a synchronous reluctance rotor injected with an aluminum cage. The session will explain how utilizing an aluminum cage in the rotor allows SynRA motor to be driven using more simple V/Hz drives vs more expensive and more complicated Vector drives which are required in traditional SynRM motors. SynRA has significant efficiency improvements over induction, allowing us to meet higher IE levels of efficiency in each rating while reducing the mechanical package to smaller stators and shorter stack lengths. We will present a comparison of Induction vs SynRA efficiency in several applications with varying loads and speeds and how that translates to power savings for the customer. In addition, we will review many of the technical challenges we faced during development of the SynRA motor including motor instability, rotor design, torque/efficiency tradeoff, and more. This technology aligns perfectly with the current broad shift to higher efficiency and VFDs. Our technical presentation will stir engineering personnel and business developers to innovate and further accelerate the current trend.
