MOTOR

The invention provides a motor, and the motor includes a rotor that rotates about a central axis and a stator that opposes the rotor in a radial direction. The stator includes a stator core with a core back, which has an annular shape, and teeth extending in the radial direction from the core back, bobbins each attached to a corresponding one of the teeth, and coil wires wound around the bobbins.The stator includes winding groups in which one coil wire is wound around the bobbins, and a number of poles of the rotor and a number of slots of the stator are 10 poles and 12 slots, 28 poles and 24slots, 42 poles and 36 slots, or 44 poles and 33 slots. 本发明提供种马达，该马达具备：转子，其以中心轴线为中心旋转；以及定子，其与转子在径向上对置。定子具有：定子铁芯，其具有环状的铁芯背部和从铁芯背部向径向延伸的多个齿；多个绕线架，其被安装于多个齿上；以及线圈线，其卷绕于绕线架上。定子包括多个由根线圈线卷绕于多个绕线架而成的绕组群，转子的极数与定子的槽数为10极12槽、28极24槽、42极36槽、44极33槽中的任个。
