摘要： The present invention provides a rotary motor including at least a field magnet having field winding, and an armature having armature winding with an electrically insulating coating material applied thereto, and the coating material includes at least two layers of: a lower-layer coating material including a first low-viscosity resin liquid; and an upper-layer coating material including a second low-viscosity resin liquid with at least hollow glass beads and a thermoplastic resin added thereto. Thus, a rotary motor can be achieved which achieves a balance between an efficiency improvement and reliability.
