摘要:
Three partial coils are accommodated in inphase slots arranged successively in the circumferential direction and also accommodated in the same conductor accommodation position set. Each layer coil is constituted by serially connecting these partial coils. Respective layer coils are connected in parallel to each other to form a phase winding.

An accessory device driving apparatus is disposed between an internal combustion engine and an accessory device of a vehicle. The driving apparatus is constructed as a coaxial dual rotor-type electric motor/generator that has two electromagnetically induction-coupled rotors to operate as a motor and a generator. One rotor is coupled with the engine to rotate at a speed higher than that of the engine, and the other rotor is coupled with the accessory device to rotate at a speed higher than that of the accessory device. The rotors are restricted from rotating in a reverse direction opposite a direction of forward rotation of the engine by one-way clutches, respectively.
摘要:
A rotational power converter is composed of a stator fixed to a cylindrical housing and a first rotor and a second rotor rotatably supported in the housing. The first rotor is driven by an internal combustion engine, and electric power is supplied to the stator from a battery, forming a rotating magnetic field in the stator. Rotational power is electromagnetically transferred from the first rotor to the second rotor that is connected to driving wheels of a vehicle. The amount of the rotational power of the second rotor is adjusted by controlling electric current supplied to the stator. The battery either supplies power or receives power according to the amount of the rotational power of the second rotor. Since the electric current is supplied only to the stator fixed in the housing, no electric feeder having slip-rings and brushes is necessary. Accordingly, the rotational power converter is made small in size and its reliability is improved.
