<p>PROBLEM TO BE SOLVED: To eliminate the need for a waterproof casing for a dynamotor for the reduced number of parts and cost reduction by providing flexible resin coating covering the coil of a stator disposed on the outer periphery of a rotor annularly, and fixed to a case. SOLUTION: Twelve stators 30, each of which is formed so that a plurality of discoidal members formed by connecting thin iron cores disposed annularly may be overlapped are disposed on the outer periphery of a rotor 26 annularly. Resin having satisfactory water proofing and insulation properties is used for the stators 30 for potting 32 the coating having flexibility capable of operating slightly. The resin is charged into parts other than an base end disposed on the outer periphery side of the stators 30, and a rotor facing end disposed on the inner periphery side of the stators 30, so that a plurality of stators 30 are integrally coated. It is thus possible to reduce entire length of an engine, a dynamotor, and a transmission, and increase insulation performance, thereby narrowing a clearance between the stator and the case of the dynamotor.</p> |
