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, in which multiple slots are formed at constant intervals in a circumferential direction and have an excitation coil, a first output coil, and a second output coil, respectively, wound there around, wherein a continuous winding number in the same direction of the first output coil and the second output coil (the winding number in the same direction is a continuous winding number based on the order of multiple slots in the circumferential direction) is twice or more, and
- the continuous winding number in the same direction of the excitation coil is a multiple of the continuous winding number in the same direction of the first output coil or the second output coil.
