Techniques for Reduction of the Cogging Torque in Claw Pole Machines with SMC Cores
Energies, 2017 As one of the main parasitic parameters in permanent magnet (PM) synchronous machines (PMSMs), cogging torque is the main component of the torque ripple, which has always been the handicap in the high-performance, low-speed drive systems.

Cogging Torque Reduction Techniques for Spoke-type IPMSM
IOP Conference Series: Materials Science and Engineering, 2017 A spoke-type interior permanent magnet synchronous motor (IPMSM) is extending its tentacles in industrial arena due to good flux-weakening capability and high power density. In many of the application, high strength of permanent magnet causes the undesirable effects of high cogging torque that can aggravate performance of the motor. High cogging torque

Cogging Torque Reduction Based on a New Pre-Slot Technique for a Small Wind Generator
Energies, 2018 Cogging torque is a pulsating, parasitic, and undesired torque ripple intrinsic of the design of a permanent magnet synchronous generator (PMSG), which should be minimized due to its adverse effects: vibration and noise. In addition, as aerodynamic power
