A Comparative Analysis of Cogging Torque Reduction in BLDC Motor Using Bifurcation and Slot Opening Variation
The utility of PM-BLDC machines is extending its tentacles in industrial arena. The key features of BLDC machines include high starting torque density and extending speed range, though the cogging torque is a threat for its performance. Various techniques have been devised to minimize cogging torque, out of which two approaches Bifurcation and Slot Opening methods have been focused in this pape...
متن کاملTorque Ripple Reduction of Electrolytic Capacitor-less BLDC Motor Drive
Brushless DC motors called BLDC are used in many industrial and non-industrial applications today for reasons such as very high efficiency, easy control method and high reliability, and their use is increasingly used in mass production applications, especially home appliances. But these motors require the use of an electric drive, even in constant speed applications. Commercialization of these ...
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 کاملA Reduction Method of Cogging Torque for Magnetic Gears
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. Generally, although these advantages, MGs suffer from inherent issues, mainly the cogging torque. Therefore, cogging torque mitigation has become an active research area....
متن کاملTorque Ripple Reduction in BLDC Motor Using Neural Network Controller
This paper presents the design and implementation of neural network controller for reducing torque ripples in brushlessDC (BLDC) motor drive with trapezoidal back-emf. The performances of the proposed neural networkcontroller are compared with the corresponding fuzzy PI controller and conventional PI controller. Simulation results are used to show the abilities and shortcomings of the proposed ...
