Cogging Torque Control in Brushless Dc Motors
During the past five years, cogging torque in HDD spindle motors has decreased drastically as designers and manufacturers have developed a better understanding of the cogging phenomenon. This paper examines various methodologies of cogging torque reduction. Timing techniques such as dead zones and tooth notching, smoothing techniques such as sinusoidal magnetization, and geometric techniques su...

Reference axial flux PMBLDC motor of 250 W, 150 rpm is designed with 48 stator slo...
متن کاملDouble Layer Magnet Design Technique for Cogging Torque Reduction of Dual Rotor Single Stator Axial Flux Brushless DC Motor
Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors. This paper presents a double-layer magnet design technique for cogging torque reduction of axial flux permanent magnet motor. Initially, 250 W, 150 rpm axial flux brus...
متن کاملMinimization of Cogging Torque and Current Control in Brushless DC Machine by Co-simulation Process
This paper deals with a comprehensive study on reducing cogging torque generated in Brushless DC motor drives (BLDC). In such drives, cogging torque suppression techniques that are practically effective in low speed as well as high speed regions are scarcely found in literature. A well-known skewing technique is adapted in the stator slots to reduce the cogging torque using CAD package Magnet 6...
متن کاملa Simple Speed Control Technique and Pulsating Torque Elimination Method in a Brushless Dc Motor
This paper presents a theoretical derivation and computer simulation of an optimal speed controller for a brushless dc motor using feedback from a linear model running in parallel with the inverter-fed model. The intent of the feedback from the linear model is to eliminate torque ripples from the inverter drive. A nonlinear model of such a motor, transformed into a linear model by a local diphe...
