Sd. Salman | T. Rajesh | B. Archana "Brush Less Dc Motor" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-1, December 2019, pp.1062-1065, URL: https://www.ijtsrd.com/papers/ijtsrd29804.pdf

Permanent Magnet (PM) Brushless DC (BLDC) motors have been widely used in industrial drives due to their high performance, high torque density and low acoustic noise. Cogging torque in these motors is caused by the reluctance change between the stator teeth and the rotor magnets. The cogging torque invariably affects the performance of the motor by giving rise to torque ripples, vibration, speed fluctuations and acoustic noise. The main objective of the research work is to explore the design methods to reduce the cogging torque in BLDC motors. This thesis consists of two parts; the first part dealing with the reshaping of Rotor Permanent Magnets and the second with the Stator Slot Modifications both for reducing the cogging torque in BLDC motors. All the proposed techniques in this thesis have been designed using CAD package MagNet. The Finite Element Analysis (FEA) is applied to all the proposed design methods and the CAD results are compared for cogging torque reductions.
