Influence of Design Parameters on the Starting Torque of a Single-Phase PM Brushless DC Motor
The starting torque of a single-phase permanent magnet brushless dc motor is investigated, for both radial and parallel magnetization. Finite element analysis is used to assess the relative merits of alternative methods of introducing the required airgap asymmetry, viz. tapered airgap, stepped airgap, asymmetric airgap, and slotted teeth. The predicted results are validated experimentally.
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 کاملOptimum Design of BrushLess DC Motor with Minimum Torque Pulsation using FEM & PSO
Despite many advantages of BrushLess DC motor, torque pulsation is one of the most important disadvantages of it. At first, an optimum primary design of BLDC motor is done using PSO algorithm. Then, other parameters for reducing the torque pulsation are considered by finite element method. It is shown that fractional slot structure has many advantages than conventional one. Both cogging and rip...
متن کاملDesign and Development of Three Phase Permanent Magnet Brushless DC (PM BLDC) Motor for Variable Speed
A major part of the power consumption in the low-wattage reciprocating compressors, used for household refrigeration units, is associated with the motor. A variable speed compressor as opposed to a single speed compressor is known to provide energy savings due to its ability to match the load demand from the pump more closely to the power delivered by the pump. The current article presents an o...
