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 ...

Series 14000 brush-commutated DC motors and gearmotors feature 11-slot skewed armatures to minimize magnetic cogging (or reluctance torque) and promote quiet and smooth operation. They suit a wide ...

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, ...

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 ...

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 ...

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 ...

A flat DC motor has ultra-flat dimensions, zero cogging torque, and a coreless motor design. It has an extremely low current consumption, low starting voltage, and a low rotor inertia for extremely ...
