摘要

Aim: To our knowledge, there is no paper in the open literature dealing with dual-redundancy high voltage BLDCM (BrushLess DC Motor) using 270 V. Section 1 of the full paper establishes the mathematical model of BLDCM's driving system, whose schematic is presented in Fig. 1; in section 1, eq. (9) is the formula for calculating the torque of the BLDCM when it works in the dual-redundancy mode. Section 2 establishes the electromagnetic field model of the BLDCM as shown in Fig. 2, simulates its electromagnetic field and compares the counter electro-motive force, torque and rotational speed for the single-winding mode respectively with those for the dual-redundancy mode: Figs. 5 and 6 for counter electro-motive force; Figs. 7 and 8 for torque; Figs. 9 and 10 for rotational speed. Section 3 establishes the magnetic-thermal coupling model of a dual-redundancy high voltage BLDCM; Fig. 12 presents the simulation results for this model, showing that high voltage does not bring appreciable increase in temperature. The simulation results show preliminarily that the dual-redundancy high-voltage BLDCM can achieve the same dynamic characteristics as single winding motor but the torque is twice.
