摘要： A starting circuit for a single-phase AC motor, comprising a main winding, a detecting circuit, a rectifying and filtering circuit, a triggering circuit, a switching circuit and a starting winding. The detecting circuit is connected in series to the main winding for transforming current parameters thereof into detecting signals. The switching circuit is connected in series to the starting winding. The rectifying and filtering circuit processes the detecting signals and the processed detecting signals to the triggering circuit. The triggering circuit enables or disables the switching circuit according to the detecting signals, so as to energize or deenergize the starting winding. The starting circuit features high reliability, long lifetime, simple circuit structure, low cost, and small size.
摘要翻译： 用于单相交流电动机的启动电路，包括主绕组，检测电路，整流和滤波电路，触发电路，开关电路和起动绕组。 检测电路与主绕组串联连接，将其电流参数变换为检测信号。 开关电路与起动绕组串联连接。 整流滤波电路将检测信号和经处理的检测信号处理到触发电路。 触发电路根据检测信号启动或禁用开关电路，以使启动绕组通电或断电。 启动电路具有可靠性高，寿命长，电路结构简单，成本低，体积小的优点。

摘要： Provided is a motor case, comprising a body, a pair of endshields disposed on both ends of the body, a cavity formed inside the body, and a pair of flangings extending from the center of the endshields; wherein the flangings extend into the cavity to form a bearing house with two opening ends; and a space is formed between the cavity and the bearing house. The invention has small distance between bearings so as to reduce vibration and noise of a motor, and features a small radial size and volume so as to make the motor case compact and simple.
