A heat resistant and explosion-proof permanent magnetic synchronous motor having a stator which includes an armature iron core made by piling up steel plates with surface covered with a mineral insulation material and disposed on an inner peripheral surface of a pressure case, an armature coil made by winding a wire covered with a mineral insulation material around a slot of the armature iron core, a can hermetically sealing the armature iron core, a back-up sleeve supporting the can at a portion where the armature iron core is not provided, and a slot piece of a mineral insulation material supporting the can at an opening portion of the slot. The motor also includes a rotor including a magnetic yoke connected to an outer peripheral surface of an actuating shaft provided to penetrate the pressure case and rotatably supported thereon, a plurality of rotor magnetic poles disposed on an outer peripheral surface of the magnetic yoke, and a non-metallic case covering an outer peripheral surface of the rotor magnetic pole.
