• Synchronous reluctance motors
• Permanent magnet motors

Synchronous motors are typically preferred when high reliability, super premium efficiency, precise motor control even at low speeds, and compact overall equipment size is required. 

Synchronous reluctance motors

The advantages of permanent magnet technology combined with the simplicity and service-friendliness of an induction platform. Each motor-drive package combines proven stator technology, an innovative magnet-free rotor design, a best-in-class industrial drive and advanced software to offer a complete, optimized solution. 

Permanent magnet motors 

The permanent magnet motor range extends the effective nominal speed range of the rugged industry workhorses down to 100 – 850 r/min. The motors can simplify drive systems by effectively eliminating the need of speed reduction devices. They are designed exclusively for a frequency converter supply, where they provide high speed accuracy even without speed sensors because they are synchronous motors without rotor slip.
