    摘要: The present invention discloses an alternating current (AC) permanent magnet motor, including a stator, a rotor, and a controller. Cable troughs and some same coil windings exist on a silicon steel sheet of a stator core. Grooves exist on the stator core, and stator permanent magnets are mounted in the grooves. The groove includes two types of grooves, namely, open grooves and enclosed grooves, and the two types of grooves are alternately laminated to form the stator core. A coil unit of the stator includes stator permanent magnets mounted in grooves of two stator cores and four same coils, and some same coil units form a three-phase stator coil. The rotor includes rotor cores, enclosed squirrel cages and rotor permanent magnets. The controller outputs a three-phase power source having a same positive and negative half sine-wave or step-wave pulse.

    摘要: A rotor includes a plurality of salient poles, each of which is formed by a plurality of plate members including steel plates that are stacked together, provided extending in a radial direction and around which a coil is wound. The plurality of salient poles has auxiliary salient poles that protrude from the salient poles between two salient poles that are adjacent to one another. The auxiliary salient poles are formed by only a first plate member that is a portion of plate members that forms the salient poles.

    摘要: An induction synchronous motor includes a unitary rotor having first and second pole type rotor cores, first and second stators, a voltage phase shifting means, and DC magnetic excitation circuits. Both of the rotor cores are mounted on a common rotor axis with a predetermined space between them. The first and second rotor windings are wound on the first and second rotor cores, respectively. A plurality of diodes is each connected in parallel between series-connection nodes of the first and second rotor windings. A plurality of rotor conductors is provided on the peripheries of and extend through the first and second rotor cores. A pair of short-circuit rings short-circuits both ends of the plurality of rotor conductors. The first and second stators surround the first and second salient pole type rotor cores, respectively, and have the same number of poles as the first and second rotor cores. The voltage phase shifting means selectively produces a phase difference of 0.degree. for starting and accelerating operations and 180.degree. for synchronous operation. The DC magnetic excitation circuits face the first and second salient pole type rotor cores, and have a different number of poles from the first and second stators.

    摘要: A synchronous motor includes a unitary rotor, a first stator, a second stator and phase-changing switches. The unitary rotor has a first rotor portion formed by a first permanent magnet and a second rotor portion formed by a second permanent magnet and an induction type rotor and these first and second rotor portions are mounted on a common rotary axle with a predetermined space provided therebetween. The first stator faces the first rotor portion for producing a first rotating magnetic field. The second stator faces the second rotor portion for producing a second rotating magnetic field and is disposed such that, at the starting operation, the attracting action or the repelling action produced between the first rotating magnetic field and the first permanent magnet is canceled by the repelling action or the attracting action produced between the second rotating magnetic field and the permanent magnetic field. The phase-changing switches are associated with either one of the first stator or the second stator and set a phase difference of 0 degree or 180 degrees between the first rotating magnetic field and the second rotating magnetic field. Due to the cancellation action, any starting interference which may otherwise be caused by the permanent magnets is made negligible.
