Technology Behind SynRM Motors

Synchronous Reluctance Motors (SynRM) are designed to offer high energy efficiency by utilizing the reluctance torque generated by the rotor’s anisotropy (difference in magnetic reluctance). Unlike traditional motors, SynRM rotors have neither magnets nor windings, which minimizes power losses and avoids the use of rare earth metals. The technology leverages the simple construction and ease of maintenance typical of induction motors while achieving performance levels close to those of permanent magnet motors.

  • Rotor Design: The rotor in a SynRM is designed with a special layout of magnetic and non-magnetic materials to create paths of low and high reluctance. This design maximizes the reluctance torque.
  • Magnet-Free: By eliminating magnets, SynRM motors avoid the environmental and supply chain issues associated with rare earth materials.
  • Efficiency: SynRM technology can achieve high efficiency due to reduced power losses in the rotor. The motors are designed to operate with variable speed drives (VSDs), optimizing energy use across different operating conditions.
  • Simplicity and Maintenance: The absence of rotor windings and magnets simplifies the construction and maintenance of SynRM motors, making them more robust and reliable over time.

The advancement to IE6 efficiency in SynRM motors reflects ongoing innovation in motor technology, aimed at meeting future energy efficiency standards and supporting sustainability goals.
