8/6极开关磁阻电机两相励磁电磁转矩分析
Analysis on two-phase excitation electromagnetic torque of 8/6 switched reluctance motor
摘要
Abstract
In order to accurately predominate the electromagnetic torque of SR motor in the state of two-phase excitation operation, the prelinear flux model was used for the four-phase 8/6 SR motor. Proceeding from the electromagnetic torque in single-phase excitation operation, the calculation results of single-phase excitation torque were spreaded to rhe two-phase excitation operation condition. According to the structural features of four-phase 8/6 SR motor, two transition stages are added in the process of the electromagnetic torque changing under a polar moment, a calculation formula of the two-phase excitation electromagnetic torque was derived, the waveforms of single-phase and the two-phase excitation torque were drawnt and the two-phase excitation operational characteristics were analyzed. The conclusion that the two-phase excitation is the important method for SR motor to increase the torque smoothness was verified by the calculation formula and the waveform drawings.关键词
