Claims

[Scope of utility model registration request]

In the rotor of an outer rotor type electric motor, a stator core punched out having a protrusion on the inner diameter part of the shaft side to fit into the key groove is attached to a fixed shaft having a spiral keyway provided on the outer diameter part of the stator. A stator for an outer rotor type electric motor, characterized in that a protrusion of the punched iron core is inserted into a keyway of a fixed shaft, and a large number of punched stator cores are laminated.
