Optimization of Cogging Torque Based on the Improved Bat Algorithm
International Journal of Information Technologies and Systems Approach, 2023 Permanent magnet motors have the advantages of high output torque, high efficiency, and low noise, but the cogging effect is obvious. The 24-slot 4-pole surface-mounted permanent magnet synchronous motor is taken as an example to reduce the cogging torque of permanent magnet synchronous motors.

Reduction of cogging torque in interior-magnet brushless machines [PDF]
IEEE Transactions on Magnetics, 2003 An investigation into the cogging torque in a four-pole interior-magnet brushless machines having either a six-slot stator and a short-pitched nonoverlapping winding or a 12-slot stator and a full-pitched overlapping winding is described. It is shown by finite-element analyses and measurements that, by appropriately defining the pole-arc to pole-pitch ...

Energies, 2021 Cogging torque is a critical dilemma in Permanent Magnet Brushless DC (PMBLDC) motors. In medium-low power PMBLDC motors, redundant vibrations and forbidding noises arise as a result of the harmonic magnetic forces created by cogging torque.

Cogging Torque Mitigation of Modular Permanent Magnet Machines [PDF]
IEEE Transactions on Magnetics, 2016 This paper proposes a novel cogging torque mitigation method for modular permanent magnet (PM) machines with flux gaps in alternate stator teeth. The slot openings of the modular PM machines are divided into two groups in a special way. By shifting the slot openings of two groups in opposite directions with the same angle, the machine cogging torque ...

Cogging Torque Characteristics of a Magnetic-Geared Motor
IEEJ Transactions on Industry Applications, 2012 Purpose The purpose of this paper is to propose a magnetic-geared motor with permanent magnets only on the high-speed rotor as a solution to the problems of magnetic gears. Magnetic gears have some advantages such as no mechanical loss and maintenance-free operation that are not observed in conventional mechanical ...

Cogging Torque Mitigation using the Unequal Rotor Slot Arcs Method based on Magnetic Permeance Distribution for Flux-Switching Machines [PDF]
Journal of Electromagnetic Engineering and SciencePermanent magnet machines, such as flux-switching permanent magnet (FSPM) machines, are characterized by cogging torque, which must be addressed because it leads to torque fluctuations.

Cogging torque minimization in transverse flux machines
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016 This paper presents the design considerations in cogging torque minimization in two types of transverse flux machines. The machines have a double stator-single rotor configuration with flux concentrating ferrite magnets. One of the machines has pole windings across each leg of an E-Core stator. Another machine has quasi-U-shaped stator cores and a ring

A Method for Reducing Cogging Torque of Integrated Propulsion Motor
Journal of Marine Science and Engineering, 2019 How to reduce the cogging torque of the integrated propeller motor is an important means to improve its noise performance because cogging torque is one of the key factors causing torque ripple.
