Abstract: An embodiment relates to a motor comprising: a housing; a stator disposed inside the housing; a rotor disposed inside the stator; and a shaft coupled to the rotor. The stator comprises a stator core, an insulator disposed on the stator core, and a coil wound around the insulator. The insulator comprises: a first body; an inside guide protruding from the inside of the first body; an outside guide protruding from the outside of the first body; a first blade portion disposed to be spaced apart from one side of the first body and to protrude from the outside guide in the radial direction; a second blade portion disposed to be spaced apart from the other side of the first body and to protrude from the outside guide in the radial direction; and a protruding portion extending from one radial side of the first blade portion. Accordingly, the motor can prevent the problem of short-circuiting between the first coil and the second coil by using the insulator, while implementing dual winding.
