    • An electric motor for controlling the tilt of a throttle valve is disclosed. A rotatable field magnet having at least two pairs of N and S poles is mounted on a rotary shaft carrying the throttle valve for rotation relative to a disk-shaped stator yoke having at least one armature coil formed therearound. The coil includes a first toroidal windings of conductor effective for the development of torque wound in one direction and a second toroidal windings of conductor similarly effective for the development of torque wound in the other direction and disposed away from said first toroidal windings of conductor circumferentially of the stator yoke at an angular interval which is equal to about 2n-1 times the pole-to-pole interval of said magnet, said first and second windings being electrically connected to each other. The first and second windings of conductor are phase shifted in spaced-apart relation to each other. Further, a spring is provided which act to urge the rotatable shaft in the direction which will cause the throttle valve to tilt to its "closed" position.
    • 公开了一种用于控制节流阀倾斜的电动机。 具有至少两对N和S极的可旋转磁场磁体安装在承载节流阀的旋转轴上,以相对于具有形成在其周围的至少一个电枢线圈的盘形定子磁轭旋转。 线圈包括有效用于在一个方向上卷绕的转矩的第一环形绕组和导体的第二环形绕组,其类似地有效地用于在另一个方向上缠绕的扭矩的发展,并且远离导体的所述第一环形绕组周向设置 所述定子磁轭的角度间隔等于所述磁体的极点间隔的大约2n-1倍,所述第一和第二绕组彼此电连接。 导体的第一和第二绕组彼此间隔开地相移。 此外,提供弹簧,其用于沿使得节流阀倾斜到其“关闭”位置的方向推动可旋转轴。
