Title: Outer rotor electric motor

Abstract: An outer rotor electric motor includes a stator, an annular rotor and a resolver. The stator includes a stator core and a plurality of coils. The stator core has a plurality of teeth that are spaced at a specified interval in a circumferential direction. The plurality of teeth protrude radially. Each of the plurality of coils is formed by winding a wire around an outer circumference of each of the plurality of teeth. The annular rotor is disposed radially outward with respect to the stator. The resolver is disposed radially inward with respect to the stator core and includes a resolver stator and a resolver rotor. The resolver stator is mounted on the stator or a case member. The resolver rotor is mounted on the annular rotor or a support member that supports the annular rotor such that the resolver rotor opposes the resolver stator.
