A new generation of
“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.”
