Claims

[Scope of utility model registration request]

A flat type consisting of a rotor that is integrally fixed to the rotor shaft together with a rotor yoke in which a flat annular permanent magnet is in contact with the end face of the base, and a stator that is disposed opposite to the permanent magnet with an air gap interposed therebetween. In an electric motor, the stator has multiple flat windings on a printed wiring board.
In the stator winding arranged approximately circularly around the rotor axis, a spiral winding is formed on the printed wiring board at the position where the flat winding is arranged using a printed wiring technique. was formed, the flat winding was arranged and fixed over the spiral winding formed by the printed wiring technique, and the flat winding and the winding formed by the printed wiring technique were connected to form a stator winding. A flat type electric motor characterized by:
