The most common machines for traction are induction and PM synchronous machines. The latter are efficient and small, but they are more expensive and less rugged than induction machines. Fault behavior is easier to manage with an induction machine. For induction machines, the back electromotive force vanishes rapidly when the stator voltages are removed.

Field‐weakening in high‐performance PMSM drives
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2002The comparative analysis of field‐weakening (FW) in vector controlled and DTC permanent magnet synchronous motor drives is performed. The results of simulations and a comprehensive set of experiments are also given. The possibility of unstable operation in the high‐speed region using DTC is emphasised.

A compact field weakening controller implementation
International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2006. SPEEDAM 2006., 2006This paper proposes a compact field weakening controller (FWC). The FWC was developed during the development of an electrically driven rear axle for a hybrid electric car. The overall control system of the vehicle, the hybrid controller (HC), delivers a reference torque for the rear drive unit (RDU).

Novel PMSM field-weakening control method
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017Voltage phase control is a novel field-weakening scheme for PMSM which was reported as more stable in high speed region. This paper provides a current ripple reduce method and a frequency-compensation method. The current ripple reduce method deals with the problem that the voltage phase control has bigger current ripple compared to the tradition method.

Field-weakening operation of cylindrical permanent-magnet motors
Proceeding of the 1996 IEEE International Conference on Control Applications IEEE International Conference on Control Applications held together with IEEE International Symposium on Intelligent Control IEEE International Symposium on Computer-Aided Contro, 2002For cylindrical permanent-magnet motors in the operation of field-weakening mode, this paper presents the way to develop maximum torque-outputs under the constraints of terminal voltages and armature currents. As compared with the conventional method of constant power operation, this design promotes the available torque-output and fully utilizes the ...

Abstract So far we have examined carefully how torque can be accurately controlled in an induction motor drive. However, we have made little mention of the demands of the load. Clearly the electromagnetic torque and load torque must be equal in magnitude and opposing in direction during steady state operation.
