Abstract
The embodiments relates to a stator used in resolvers, in which multiple slots are formed at constant intervals in the circumferential direction and have an excitation coil, a first output coil, and a second output coil are respectively wound around the multiple slots. The excitation coil is wound by a number of windings that is changed on the basis of a sinusoidal wave in accordance with the order of the multiple slots in the circumferential direction. After the first output coil is wound by a number of windings resulting from the division of the total number of windings by a constant ratio, the second output coil is wound, and then the rest of the first output coil is wound.
Claims7
A stator used in resolvers, comprising:
- multiple slots defined at constant intervals in a circumferential direction;
- a first output coil having a continuous number of windings around at least two slots in a same winding direction;
- a second output coil having a continuous number of windings around at least two slots in a same winding direction, wherein the same winding direction of the first output coil and the second output coil are the same;
- and
- an excitation coil having a continuous number of windings around a plurality of consecutive slots in the same winding direction, where the plurality of consecutive slots is a multiple of the at least two slots of the first output coil or the second output coil.
