Wide Speed Control of Interior Permanent Magnet Synchronous Motor.
IEEJ Transactions on Industry Applications, 1994 Permanent magnet synchronous (PM) motors are widely used for industrial applications. In the PM motor drives, it is difficult to achieve the wide speed and constant power operations, which are desired in traction and spindle drives, because the field-flux of PM motor is uncontrollable and as a result the field-weakening control is not available.

Performance verification of DR-PMSM for traction system according to permanent magnet shape
AIP Advances, 2020 Unlike the conventional railway traction motor, the concept of the dual-rotor in a dual-rotor permanent magnet synchronous motor (DR-PMSM) is that two rotors are mounted on the same rotation axis, and the outer rotor and the inner rotor rotate at ...

New 5-Phase Concentrated Winding Machine with Bi-Harmonic Rotor for Automotive Application [PDF]
, 2014 For a power range from 10 to 30 kW, 5-phase machines are well adapted to low-voltage (48V) supply thanks to their reduced current per phase. For three-phase machines but with higher voltages (>120V), machines with a number of slots per pole and per phase
