Analysis of the Impact of Magnetic Materials on Cogging Torque in Brushless DC Motor
Advances in Materials Science and Engineering, 2021 The cogging torque is the most significant issue in permanent magnet applications, since it has a negative impact on machine performance. In this article, the impact of magnetic materials on cogging torque is analyzed on brushless DC motors (BLDC).

A novel cogging torque measurement method for multi slot/pole permanent magnet motor
IET Electric Power Applications, 2023 The adverse effect on speed ripple and vibration makes it necessary to evaluate the cogging torque. Due to the tolerance of stator and rotor stacks as well as nonuniform magnetization of permanent magnet, the amplitude of cogging torque is unequal in ...

Cogging torque in slotless permanent magnet machines [PDF]
Journal of Electrical Engineering, 2020 Abstract Slotless permanent magnet machines theoretically do not produce any cogging torque, provided the stator inner surface reluctance remains unchanged. However, a cogging torque may occur due to a change in the electromagnetic design following material cost reduction in the manufacturing process.

A Reduction Method of Cogging Torque for Magnetic Gears [PDF]
Iranian Journal of Electrical and Electronic Engineering, 2023 Nowadays, magnetic gears (MGs) have become an alternative choice for mechanical gears because of their low maintenance, improved durability, indirect contact between inner and outer rotors, no lubrication, and high efficiency.

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 Reduction in Permanent Magnet Machines [PDF]
IEEE Transactions on Industry Applications, 2006 This paper examines two methods - magnet shifting and optimizing the magnet pole arc - for reducing cogging torque in permanent magnet machines. The methods were applied to existing machine designs and their performance was calculated using finite-element analysis (FEA).
