摘要： An electric motor has a housing, a rotor rotatably installed in the housing, n permanent magnets with the same polarity fixed at an inner surface of the housing. The rotor is a wound armature having a plurality of teeth extending in a radial direction. The housing includes n inner projecting parts, the permanent magnets and the inner projecting parts being alternately arranged in a circumferential direction about the rotor. The magnets generate 2n magnetic circuits via the housing and the rotor, n being an integer greater than one. The size of at least a portion of a first air gap formed between the permanent magnets and the rotor is greater than the size of at least a portion of a second air gap formed between the inner projecting parts and the rotor.

摘要： A window lift has a motor and a gearbox. The motor is a permanent magnet motor, comprising a stator and a rotor rotatably mounted to the stator. The stator or the rotor comprises a housing and magnets fixed to inner surface of the housing. The radial cross section of the housing comprises n side portions and n connecting portions, where n is an integer greater than 2. Adjacent side portions are connected together by one corresponding connecting portion and the magnets are fixed at portions corresponding to the connecting portions. The radial cross section of each side portion is like a convex curve line, which is curved outwardly relative to a straight line passing through the two ends of the convex curve line.

摘要： An electric motor comprises a stator and a rotor received in the stator. The stator comprises a shell. The shape of a cross section of the shell perpendicular to the rotor axis is a polygon. The shell comprises a plurality of side walls and arcuate connection portions connecting neighboring side walls. The stator comprises 2n magnets disposed in the arcuate connection portions. The magnets form 2m magnetic poles, where m, n are unequal positive integers. Optionally, m is equal to half or twice n. The permanent magnets of the motor are located in the inner angle of polygon shell. Thus the diameter of rotor can be the greater, and the power density of motor can be increased in the same volume.
摘要翻译：电动机包括定子和接收在定子中的转子。定子包括壳体。垂直于转子轴线的壳体的横截面形状是多边形。壳体包括连接相邻侧壁的多个侧壁和弓形连接部分。定子包括设置在弓形连接部分中的2n个磁体。磁体形成2m个磁极，其中m，n是不等的正整数。可选地，m等于一半或两倍n。电机的永磁体位于多边形外壳的内角。因此，转子的直径可以更大，并且电机的功率密度可以在相同体积内增加。
