Abstract: This article presents an arc-shaped rotor-notch topology for reducing cogging torque in axial flux permanent magnet (AFPM) motors. Unlike traditional techniques such as magnet skewing or ...

The project focuses on designing and building a mechanical test rig for measuring the cogging torque in three-phase BLDC and PMSM motors. The motivation behind the project is that cogging torque — the ...

Brushless dc motors without wire windings rotate smoothly with practically no cogging or torque ripple. Semiconductor-wafer production, servo writers, and other close tolerance applications need ...

Celera Motion has launched a new frameless motor that provides high torque density in a compact form factor, combined with smooth motion. The Omni+™ motor series, distributed to the UK by INMOCO, ...

Cheap, brushless motors may be the workhorses behind our RC planes and quadcopters these days, but we’ve never seen them in any application that requires low-speed precision. Why? Sadly, cheap ...

Almost two years ago, a research team showed that it was possible to get fine motor control from cheap, brushless DC motors. Normally this is not feasible because the motors are built-in such a way ...

BEDFORD, Mass.--(BUSINESS WIRE)--Celera Motion, a leader in precision motion component and sub-system solutions and a business unit of Novanta Corporation introduces a new direct drive motor platform, ...

NUM’s new TMX series direct drive motors have an extremely low cogging torque, making them suitable for applications that demand very smooth and accurate rotation, especially at low speeds. Typical ...
