Claims

[Scope of utility model registration request]

a pair of ring-shaped upper and lower yokes that have a large number of magnetic poles on the inner circumferential side and are magnetically coupled at the outer circumferential wall so that the magnetic poles face each other with a predetermined gap therebetween; In the stator structure of a step motor consisting of a ring-shaped coil whose terminal wire is drawn out from an opening provided in an outer circumferential wall, a flexible coil having a conductive portion formed on its surface and a protrusion that can be inserted through the opening is arranged in series. A stator structure for a step motor, wherein a terminal plate made of a printed wiring board is provided on the coil, and a terminal wire of the coil is connected to the conductive part.
