    • An induction motor capable of obtaining a high power characteristic in a wide range without producing induced voltage. A winding for each phase is composed of a plurality of winding components having the same number of turns. When high torque is needed with low speed rotation, a Y-connection in which winding components for each phase are connected in series is formed as shown in FIG. 2a. For medium low speed rotation, a &Dgr;-connection in which winding components for each phase are connected in series is formed as shown in FIG. 2b. For medium high speed rotation, a Y-connection in which winding components for each phase are connected in parallel is formed as shown in FIG. 2c. For high speed rotation, a &agr;-connection in which winding components for each phase are connected in parallel is formed as shown in FIG. 2d. Using the entire winding for each phase, the number of turns is decreased stage by stage to switch from low speed rotation to high speed rotation. Since there is no unused part of windings, there is no problem of induced voltage. A fall in power at the time of switching the winding formation can be restrained, so that a high power characteristic can be obtained in a wide range.
    • 一种能够在不产生感应电压的情况下在宽范围内获得高功率特性的感应电动机。 每相的绕组由具有相同匝数的多个绕组部件组成。 当低速旋转需要高扭矩时,如图3所示,形成其中各相的绕组部分串联连接的Y形连接。 2a。 对于中低速旋转,如图3所示,形成其中各相的绕组部分串联连接的DELTA连接。 2b。 对于中等高速旋转,如图3所示,形成并联连接各相的绕组部件的Y形连接。 2c。 为了高速旋转,如图3所示,形成其中各相的绕组部件并联连接的α连接。 2d。 对于每个相,使用整个绕组,匝数逐步减少,从低速旋转切换到高速旋转。 由于没有未使用的绕组部分,所以没有感应电压的问题。 可以抑制切换绕组形成时的功率下降,从而可以在宽范围内获得高功率特性。

    • A stator (10) for an induction machine for a vehicle has a cylindrical core (12) with inner and outer slots (26, 28) extending longitudinally along the inner and outer peripheries between the end faces (22, 24). Each outer slot is associated with several adjacent inner slots. A plurality of toroidal coils (14) are wound about the core and laid in the inner and outer slots. Each coil occupies a single inner slot and is laid in the associated outer slot thereby minimizing the distance the coil extends from the end faces and minimizing the length of the induction machine. The toroidal coils are configured for an arbitrary pole phase modulation wherein the coils are configured with variable numbers of phases and poles for providing maximum torque for cranking and switchable to a another phase and pole configuration for alternator operation. An adaptor ring (36) circumferentially positioned about the stator improves mechanical strength, and provides a coolant channel manifold (34) for removing heat produced in stator windings during operation.

    • An ac spindle motor (10) for driving a spindle motor of a machine tool provided with a rotor (14) having an output shaft (12) connected to the spindle, and a stator (16) surrounding the rotor and having a laminated core (20) serving as a yoke, and stator winding assemblies of three phases (U-phase, V-phase, W-phase). The stator winding assembly of each phase (18u, 18v, 18w) has: windings (C.sub.2, C.sub.4) of a first group which are energized for a rotation of the spindle in both a low-speed range not higher than a given speed, and a high-speed range above the given speed; windings (C.sub.1, C.sub.3) of a second group energized only for a rotation of the spindle in the low-speed range; and electrical contact means (S1, S2, S3, S4) controlled so that the windings (C.sub.1, C.sub.2, C.sub.3, C.sub.4) of the first and second groups are energized to generate a first multipolar revolving magnetic field for the rotation of the spindle in the low-speed range, and so that only the windings (C.sub.2, C.sub.4) of the first group are energized to generate second multipolar revolving magnetic field having magnetic poles less than those of the first multipolar revolving magnetic field for the rotation of the spindle in the high-speed range. The operating mode of the ac spindle motor is changed between a high-speed mode and a low-speed mode by changing the ampere-turn of the windings and the number of poles of the revolving magnetic field.

    • A pole change type motor has armature windings wound around an iron core in a coaxial fashion with a P (for example 2) number of poles for a high speed operation, which armature windings provide a Q (for example 20) number of poles for a low speed operation by changing the external connections of the windings.
