The invention provides a wiring structure of a single-phase capacitance running motor. The wiring structure comprises a main winding set, an auxiliary winding set and a capacitor. The capacitor and the connecting end of the main winding set are moved into the main winding set in a phase shifting mode, compared with a T-type connection mode and an L-type connection mode, the turn number of the main winding set serving as a working winding is reduced, magnetomotive force of the winding is reduced, so that the induction electromagnetism of the auxiliary winding set is reduced, namely voltage of the capacitor end is reduced. Meanwhile, when the single-phase capacitance running motor runs at a high gear, the turn number of the induction winding is smaller than that of the T-type induction winding, namely induction voltage is correspondingly reduced. The wiring structure can effectively reduce the phenomena that the induction voltage exceeds standard, and the voltage of the capacitor end exceeds standard, and work reliability of the single-phase capacitance running motor is improved.
Description
technical field [0001] The present invention relates to the technical field of single-phase capacitor-operated motors, and more specifically, relates to a wiring structure of single-phase capacitor-operated motors. Background technique [0002] In order to meet different usage requirements, single-phase capacitor running motors generally adopt multi-gear speed regulation. At present, the single-phase capacitor-operated motors used in the industry mainly have T-type and L-type connections. For details, see figure 1 with figure 2 . When the T-type connection is adopted, the main winding is provided with winding taps SH1, winding taps H1, winding taps M1 and winding taps L1, the power lines are connected to different winding taps, and the motor runs in different gears. But the T-type is easy to induce voltage exceeding the standard for multiple gears. The reason is that the induction voltage limit is based on the high-end operation of the T-type. When the speed regulating w...
