Nidec Hits Energy-Efficiency Sweet Spot with Dyneo Induction Motors

Combining the performance of synchronous permanent magnet technology and advanced smart system connectivity, Nidec Leroy-Somer is drawing the attention of engineers conscious about energy efficiency with its Dyneo induction motors for industrial applications. Designed for pairing with variable frequency drives, the motors meet the latest standards of leading governing bodies as they tighten restrictions on energy use. 

Based on the mechanical platform of its IMfinity induction motors, the new Dyneo line is built with a rotor free of rare-earth material, windings with reinforced insulation plus advanced digitization and sensing features. The motors are permanent magnet-assisted synchronous reluctance in design, incorporating all the benefits of induction and synchronous permanent magnet technologies including low rotor loss, the company notes. 

Ranging from 11 to 430 kW for speeds up to 6,000 rpm, there are two variants. One version is interchangeable with a standard IEC motor, the other an extremely compact version to address space constraints and optimize energy consumption. Key applications include industrial refrigeration, compression, pumping, ventilation, extrusion, grinding and process industries. This is also an easy-to-implement solution for applications requiring high torque at high speed. High starting performance in sensorless mode avoids the need for an encoder. For more info, see
