A new generation of high-efficiency, silent & rare-earth free reluctance motors

The Electric Motor Talks are an initiative of the World Magnetic Conference, the University of L’Aquila and QUiCKFairs. They are the answer in case the epidemiological circumstances make it advisable not to hold Coiltech Deutschland 2021 in May.  The Spin technical team ‘ll talk about three topics. The other talks are visible at the bottom of the page.


Synchronous reluctance (SR) motors and the Ferrite assisted versions are today valid alternatives to PM synchronous machines with Rare Earth magnets.

In this paper it will be shown how vibrations behaviour has been investigated to get a very low torque and force ripples by means of multidisciplinary optimization. Motor drive topic was also faced, characterizing the Id, Iq-Ld, Lq behaviour by model based 1D simulations: a commercial product to drive the motors was tested and then adopted.

Some solutions of Rare Earth free SR motors developed by Spin Applicazioni Magnetiche are also presented for different power and speed values, including a detailed comparison between simulation and test results concerning the electromagnetic and vibration response of the motor.

SR motors and Ferrite PMASR versions are now suitable for low-cost / high-performance use in e-mobility, industrial and automation applications.”
