    • Structure for maintaining accurate spacing between opposed pole elements of a split-field coil structure. The motor structure includes a support for supporting the armature for rotation about an axis and a field coil structure having opposed C-shaped laminated cores. Each core has a pair of legs forming motor poles, each pole being defined by an arcuate surface spaced radially from the armature and a distal end surface. The core further defines a bight portion extending between the legs. The field coil is wound about a two-piece bobbin which serves further to retain the laminations of the field coil in stacked, assembled relationship. The end surfaces of the legs of the cores are in spaced, opposed alignment, with the support portion fitting therebetween for providing the accurately maintained minimum spacing between the pole end surfaces.
    • 用于保持分离场线圈结构的相对极元件之间精确间隔的结构。 马达结构包括用于支撑衔铁以绕轴线转动的支撑件和具有相对的C形叠片铁芯的励磁线圈结构。 每个芯具有形成电机极的一对腿,每个极由与电枢径向间隔开的弧形表面和远端表面限定。 芯部还限定了在腿之间延伸的弯曲部分。 励磁线圈缠绕在两片式的线轴上,其进一步用于将磁场线圈的叠片保持在堆叠的组装关系中。 芯部的腿部的端表面是间隔开的相对的对准方式,其中支撑部分配合在其间,用于在极端面之间提供精确维持的最小间距。

    • A motor controller for a single phase induction motor (SPIM), wherein the SPIM is driven by two windings, a line winding connected to the ac line and a control winding driven by the controller. The SPIM torque and hence the speed and direction is controlled by the voltage output of the controller for all speeds below the synchronous speed (set by ac line frequency). The controller adjusts the amplitude, the phase angle relative to the line winding, and the frequency of the voltage for the desired SPIM responses. The controller can also selectively switch power to the line winding for a different operating mode with both windings at below synchronous speed. Or, the controller can open the connection to the line winding after starting, and operate the SPIM via the control winding at any speed by adjusting the amplitude and frequency of the controller voltage.
    • 用于单相感应电动机(SPIM)的电动机控制器,其中SPIM由两个绕组驱动,连接到ac线的线绕组和由控制器驱动的控制绕组。 SPIM扭矩,因此速度和方向由控制器的电压输出控制,所有速度低于同步速度(由交流线路频率设置)。 控制器调节幅度,相对于线绕组的相位角以及所需SPIM响应的电压频率。 控制器还可以在两个绕组处于低于同步速度的情况下,选择性地将功率切换到不同工作模式的线绕组。 或者,控制器可以在启动后打开与线绕组的连接,并通过调节控制器电压的幅度和频率,通过控制绕组以任意速度操作SPIM。

    • A method and apparatus for balancing of a motor armature and fan coupled thereto is disclosed. The apparatus includes a pair of spaced end brackets for supporting an armature of the motor and the fan for rotary movement. At least one motor bracket is coupled between the end brackets and includes means for detachably mounting a set of field coils for the motor thereon. The motor bracket further includes a recess therein which, when the set of field coils is detached from the motor bracket, exposes the armature to permit the armature and fan to be rotated as a unit so that the balance of the unit can be determined. The method and apparatus are particularly adavantageous for balancing a motor-fan system in which the motor is of the split-field coil type.
