The invention discloses a high-power marine permanent magnet propulsion motor with double stators and double rotors, which solves the problem of how to save the occupied space of a main propulsion motor on a ship and keep the functions of one for use and one for standby. The two motors are integrated in the same base, that is, the two stators are arranged in the same base, and the two rotors are arranged on the same rotor rotating shaft, so that the purpose of saving the occupied space of the main push motor is achieved; a support connected to a rotor rotating shaft is arranged to be of a spoke structure, a reinforcing connecting plate is arranged between every two adjacent spoke plates, and lightening holes are formed in the reinforcing connecting plates, so that the effect of overcoming large rotating stress is achieved; a fractional-slot skewed slot form is adopted for the wire embedding slots on the stator cores to reduce the cogging torque, and the opposite skewed cogging slots are adopted on the two stator cores, namely, one stator cogging slot adopts a leftward-skewed form, and the other stator cogging slot adopts a rightward-skewed form, so that the effect of balancing the axial force of the motor is achieved, and the vibration and noise of the motor are effectively reduced.
本发明公开了一种双定子双转子的大功率船用永磁推进电动机,解决了在船舶上如何节省主推电机的占用空间并保持一用一备功能的问题;将两台电机集成在同一个机座中,即在同一机座中设置两个定子,将两个转子设置在同一转子转轴上,达到了节省主推电机占用空间的目的;将连接在转子转轴上的支架设置成轮辐结构,并在相邻轮辐板之间设置加强连接板,并在这些板上设置减重孔,达到克服大的旋转应力的作用;将定子铁芯上的嵌线槽采用分数槽斜槽形式,以降低齿槽转矩,并在两定子铁芯上采用相反的斜槽齿槽,即一个定子齿槽采用左斜形式,另一个定子齿槽采用右斜形式,起到平衡电机轴向力的作用,有效降低电机振动和噪声。
