摘要： A hybrid single-phase variable reluctance motor (31) has a stator (33) having a plurality of inwardly salient teeth (41A-41D) terminating at a central bore (37). The teeth are arranged in generally diametrically opposed pairs of teeth and are generally evenly spaced around the bore. A phase winding (43) is operatively associated with one pair of the stator teeth. The winding, when energized, causes a temporary magnetization of the stator teeth. A rotor (35) is disposed for rotation in the bore and has outwardly salient teeth (45A, 45B) generally diametrically opposed to each other. A permanent magnet (53) is disposed adjacent the bore at the end of one tooth (41D) of a second pair (41C, 41D) of stator teeth. One tooth (41D) of the second pair of stator teeth is offset with respect to a longitudinal axis (A.sub.1) of the second pair of teeth. This offset acts to eliminate a stable detent position in which the rotor could otherwise "park" itself when it stops running. Parking in such a position makes it difficult to restart the motor.
摘要翻译：混合单相可变磁阻电动机（31）具有定子（33），其具有终止于中心孔（37）的多个向内凸齿（41A-41D）。齿通常沿径向相对的齿排布置，并且通常围绕孔均匀间隔开。相绕组（43）与一对定子齿可操作地相关联。绕组在通电时会导致定子齿的暂时磁化。转子（35）设置成用于在孔中旋转并且具有通常沿径向相对的向外凸出的齿（45A，45B）。在第二对定子齿（41C，41D）的一个齿（41D）的端部处邻近孔处设置永磁体（53）。第二对定子齿的一个齿（41D）相对于第二对齿的纵向轴线（A1）偏移。该偏移用于消除稳定的制动位置，其中转子可以在其停止运行时以其它方式“停放”自身。在这样的位置停车使得难以重启电动机。

摘要： A reluctance motor comprises a stator (S) provided with coils (W1, W2), and a rotor (R). The rotor R has pairs of positions of stable equilibrium and pairs of positions of unstable equilibrium. The reluctance motor is started by first bringing the rotor into a first position of stable equilibrium (.theta.=-.theta.ms) by means of a first energizing current and subsequently rotating it towards a second (.theta.=0) of stable equilibrium by means of a second energizing current.

摘要： A domestic ice-cream maker comprises a refrigerated bowl-shaped container for an ice-cream mass; a rotatable stirring tool associated with such container for scraping off ice-cream freezing at a refrigerated surface of the container; and a single-phase synchronous motor for rotating the stirring tool, such motor having a maximum permissible operating temperature for making the ice-cream. A transmission path including a reduction mechanism extends between the synchronous motor and the stirring tool. Backlash is provided in the reduction mechanism as overload protection for the synchronous motor, the backlash acting in both directions of rotation of the motor and corresponding in each such direction of rotation to at least 10 revolutions of the motor, the motor, upon being blocked in either direction of rotation, reversing its direction of rotation and passing through the range of the backlash without exceeding its maximum permissible operating temperature.

摘要： A synchronous motor which has a ring-shaped stator with a radially magnetized ring-shaped permanent magnet and an external housing of a material of high permeability to complete the magnetic circuit. At the inner side of this ring-shaped stator lies a rotor having a central core provided at its ends with pole rings of a material of high permeability. The coil of the motor is provided in the center of the stator and mounted between the pole rings. This construction gives rise to a high magnetic flux in the permanent magnet in the region of the poles of the rotor, which in turn, provides a high driving torque; while the rotor is made exclusively of material of high permeability, having a low weight and a low moment of inertia. Such motors, even when constructed to operate at relatively high power, are thus assured of positive starting.

摘要： A stator arrangement for a small motor, particularly of the claw-pole type. The stator arrangement is provided with first and second stator subassemblies which are formed from respective pairs of pole laminations which are contained within a common housing. The common housing is provided with axial slots having predetermined circumferential width and axial depth for engaging radial protrusions of the pole laminations. In this manner, the axial and rotative orientation of the pole laminations, and the stator subassemblies, are advantageously predetermined within the cylindrical housing.

摘要： A disc machine has a stator from which teeth and a central boss project axially in the same direction with the central boss projecting beyond the teeth. An AC winding is wound through the slots between the teeth while a DC winding surrounds the central boss. A bar-like rotor has a central aperture and is mounted for rotation so that the boss passes through the central aperture with an axial gap between the rotor and the teeth.
