  • Permanent-magnet six-pole synchronous electrodynamic machine
    Patent number: 4709179
    Abstract: The machine includes a rotor of the flux concentration type. Six permanent magnets of the high-energy type are mounted on a shaft. Between the magnets are placed pole pieces made of ferrosilicon magnetic sheets. A stator is composed of ferrosilicon magnetic material in which are formed a plurality of half-closed slots which receive inducted windings. An air gap is formed between the rotor and the stator. The ratio r.sub.1 of the height of the section of the magnets through which the induction flux passes to the width of the air gap is between 0.281 and 0.344.
