A subdomain analytical model for multi‐harmonic air‐gap subdomains is proposed to predict motor magnetic fields containing complex harmonic components. Theoretical analysis demonstrates that this model effectively reduces the matrix dimension during analytical computation, resulting in lower computational time costs for the same harmonic order while ...

Active cogging torque construction by the weld slot design in a positioning servo system
The cogging torque is usually considered as an adverse effect of the PM machine servo system. This paper presents a new perspective that the cogging torque can be exploited in many practical situations as long as the speed ripple can be suppressed.

Force Analysis and Torque Production of the Doubly Salient Parallel Path Magnetic Machine
This paper presents an in‐depth mathematical analysis of torque and force production mechanisms in the Doubly Salient Parallel Path Magnetic Motor (DS‐PPMM). Electromagnetic force distribution, torque ripple characteristics and the contributions of magnetic salience are analysed through analytical modelling and verified by finite element analysis.

Analysis for cogging Torque Reduction Method of Outer Rotor Hybrid Excitation Flux Switching Machine
Cogging torque, caused by the interaction of stator slots and rotor magnets, degrades motor performance by producing noise, vibration, and torque ripple even without current in the windings.
