Abstract
Disclosed is 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 core, and an insulator arranged between the stator core and the coil, and the insulator comprises an upper insulator and a lower insulator. An upper body of the upper insulator comprises: a first side wall part; a second side wall part arranged to the spaced apart from the first side wall part; and a first cover part extending from an end of the first side wall part and connected to an end on one side of the second side wall part, wherein the number of a plurality of first grooves formed on the first side wall part is different from the number of a plurality of second grooves formed on the second side wall part. Accordingly, when a coil with an increased diameter is used, the performance of the motor can be improved by implementing asymmetric wiring of the coil by using the insulator for guiding the arrangement of the coil.
