Abstract

The utility model relates to a control circuit for improving the starting torque of a single-phase electromotor, which is characterized by comprising a main winding, a secondary winding A, a secondary winding B and an operating capacitor, wherein the secondary winding A is connected with the main winding in parallel after connecting with a normally-closed contact of a centrifugal switch, the secondary winding B and the operating capacitor in series, one end of the secondary winding B, which is connected with the operating capacitor, is provided with the normally-closed contact of the centrifugal switch, and two ends of the main winding are connected with the single-phase power supply. The control circuit is beneficial for improving the starting torque of a single-phase motor, which solves the problem that a starting capacitor in a single-phase motor is easy to damage, thereby greatly improving the service span of the integral body of a motor.

Description

Improve the control circuit of single-phase motor starting torque
Technical field
The utility model relates to a kind of control circuit that improves the single-phase motor starting torque.
Technical background
Single-phase motor is a kind of simple in structure, cheap, sturdy and durable, convenient maintenance, the reliable motor of utilization, can be applicable to most of power-equipments such as various pump class, detachment machine, air blast and Transport Machinery etc.As being to disclose a kind of asynchronous motor in 200420033976.0 the Chinese patent at one piece of application number with heat protection; it comprises main winding, auxiliary winding, working capacitor and starting capacitance; in parallel with working capacitor after starting capacitance is connected with centrifugal switch and thermal protector successively, connect with auxiliary winding: auxiliary winding circuit and main winding are connected in the power supply again.This scheme helps making in monopole asynchronous motor starting and the operation process, realizes being switched on or switched off automatically of starting capacitance, makes its running reach efficient effect automatically.But, thereby cause the useful life of motor complete machine low owing to starting capacitance is damaged easily.
Summary of the invention
The purpose of this utility model provides a kind of control circuit that improves the single-phase motor starting torque, this circuit helps improving the starting torque of unit motor, solve the flimsy problem of starting capacitance in the single-phase motor, thus the useful life of improving the motor complete machine greatly.
The technical solution of the utility model is achieved in that it comprises main winding, auxiliary winding A, auxiliary winding B and running electric capacity, described auxiliary winding A is in parallel be in series back and main winding of centrifugal switch, auxiliary winding B and running electric capacity successively, the end that described auxiliary winding B is connected with running electric capacity is provided with the normally opened contact of centrifugal switch, the other end of described auxiliary winding B is provided with the normally-closed contact of centrifugal switch, and the two ends of described main winding are connected with the two ends of single phase poaer supply.
The utility model has the advantages that reasonable in designly, simple structure helps improving the starting torque of unit motor, solves the flimsy problem of starting capacitance in the single-phase motor, thus the useful life of improving the motor complete machine greatly.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Embodiment
Below, in conjunction with the accompanying drawings embodiment of the present utility model is further elaborated.
As shown in Figure 1, this circuit comprises main winding (2), auxiliary winding A (3), auxiliary winding B (5) and running electric capacity (4), described auxiliary winding A is in parallel be in series back and main winding of the normally-closed contact (b) of centrifugal switch, auxiliary winding B and running electric capacity successively, the end that described auxiliary winding B is connected with running electric capacity is provided with the normally opened contact (c) of centrifugal switch, and the two ends of described main winding are connected with single phase poaer supply (1).
When energized, because the normally-closed contact closure of centrifugal switch, auxiliary winding A and auxiliary winding B are in series, and make total auxiliary winding number of turn bigger, are beneficial to improve the starting torque of unit motor.After electrical motors arrives predetermined rotating speed, the centrifugal switch action, normally-closed contact disconnects, and the normally opened contact closure is excised auxiliary winding B, finishes the starting process of motor.
In order to help adjusting the starting torque of single-phase motor, can adjust the number of turn of auxiliary winding B.
