Claims

[Scope of utility model registration request]

In a magnetic electric motor whose field is a plurality of magnets attached to the outer diameter of a rotating shaft, a portion near the radial end of the magnet has a thin wall portion that is thinner than at least other portions. A magnet-type electric motor, characterized in that the boundary between the thin-walled part and the thick-walled part of the magnet is disposed so as to be non-parallel to the slot of the stator core extending in the axial direction. rotor.
