Patent ID: 8575799

Claim:
An outer rotor electric motor comprising: a stator comprising: a stator core having a plurality of teeth that are spaced at a specified interval in a circumferential direction, the plurality of teeth protruding radially; and a plurality of coils each of which is formed by winding a wire around an outer circumference of each of the plurality of teeth; an annular rotor disposed radially outward with respect to the stator; and a resolver disposed radially inward with respect to the stator core and comprising: a resolver stator that is mounted on the stator or a case member; and a resolver rotor that is mounted on the annular rotor or a support member that supports the annular rotor such that the resolver rotor opposes the resolver stator, wherein the resolver stator is held by a resolver stator holder, and the resolver stator holder is fastened to the case member together with the stator core using a common fastening member, and wherein a part of the resolver stator holder and a part of the stator core are sandwiched between the fastening member and the case member.
