Abstract
An embodiment provides a motor comprising: a stator; a rotor provided inside the stator; and a shaft coupled to the rotor, wherein the stator comprises a stator core, a coil wound around the stator coil, and an insulator provided between the stator core and the coil. The insulator comprises an upper insulator and a lower insulator, wherein an upper body of the upper insulator comprises: a first side wall portion; a second side wall portion provided spaced apart from the first side wall portion; and a first cover portion extending from an end portion of the first side wall portion and connected to an end portion of one side of the second side wall portion, wherein the number of a plurality of first grooves formed in the first side wall portion is different from the number of a plurality of second grooves formed in the second side wall portion. Accordingly, when a coil having an increased diameter is used, asymmetrical winding of the coil is realized using an insulator which guides placement of the coil, and thus performance of the motor can be improved.
