Instead, it contains stacked steel plates with intervening spaces that form a light but robust structure. The difference is on the inside, as the innovative rotor structure has no windings at all. What makes a SynRM motor different?Įxternally, a SynRM motor looks like a standard induction motor.
However, industrial case studies with SynRM motor and VSD packages have shown dramatic reductions in energy bills compared with the motors replaced. The exact energy savings depend on the specific application and operating conditions. Using IE5 SynRM motors can reduce energy losses by 40% as well as significantly reducing energy consumption compared to the IE3 induction motors mandated by the latest regulations.

Industrial operators can upgrade now and enjoy practical and economic advantages – as well as demonstrating their environmental responsibility. This goes well beyond the EU Ecodesign regulation, but some manufacturers are already supplying motors compliant with it.
There is also the IE5 ultra-premium rating. From July 2021, IE3 is the minimum standard for most industrial motors, including those used with VSDs. The synchronous reluctance (SynRM) motor is a significant development in energy efficient operation. The EU Ecodesign Regulation for low-voltage motors has established minimum efficiency levels based on the International Efficiency (IE) classes defined by the International Electrotechnical Commission (IEC).
