A reduction method of cogging torque for IPMSM

2005 International Conference on Electrical Machines and Systems, 2005
This paper describes a reduction technique of the cogging torque in an interior permanent magnet synchronous motor (IPMSM). IPMSM usually has the flux barrier for preventing the short circuit of magnetic flux near the magnet. The flux barrier can reduce the cogging torque, and therefore the shape of the flux barrier of IPMSM with concentrated winding ...

A Method for Improving Torque Performances of IPMSM

2020 8th International Conference on Power Electronics Systems and Applications (PESA), 2020
This paper presents a method for improving torque performances by shifting magnets and optimal flux-barrier shape in Interior Permanent Magnet Synchronous Machine (IPMSM), in which cogging torque and torque ripple are significantly reduced together, while average torque is preserved.

Force and torque computations with hybrid methods

IEEE Transactions on Magnetics, 1999
Alternative methods are presented for computing the magnetic forces and torques associated with hybrid solutions of magnetostatic or eddy current problems. The challenge is to retrieve the forces not just accurately but also with as little extra work as possible. The authors analyze several methods and the errors inherent in them.

Kinematic Analysis Method: Force and Torque

SAE Technical Paper Series, 1965
<div class="htmlview paragraph">The program for force and torque analysis of planar and spatial linkages is part of the KAM (Kinematic Analysis Method) system. A general set of force and moment equilibrium equations has been developed. The program generates the parameters for the equations from a computer stored description (the plex) of a ...
