Guide board structure of centrifugal switch for single-phase induction machine

Abstract

The invention relates to a guide plate structure of a centrifugal switch for a single-phase induction motor. The guide plate structure is mainly composed of a rotating shaft, a sleeve, a slider and a centrifugal cone. The guide plate of the sleeve is formed along its length direction with a The groove of the guide plate has a certain curvature and is concave, and one side of the installation hole of the guide plate of the centrifugal cone is formed with a raised portion of the guide plate corresponding to the groove of the guide plate. In addition, the groove portion of the guide plate has the same curvature as the moving locus of the above-mentioned centrifugal cone. The guide plate structure of the centrifugal switch for a single-phase induction motor of the present invention can prevent the wear of the guide plate due to frictional force, and at the same time enable the centrifugal cone to move flexibly, thereby improving the reliability of the product. The invention is a guide plate structure of a centrifugal switch for a single-phase induction motor which is easy to assemble, prevents wear of components and can prolong life.

Description

technical field [0001] The present invention relates to a single-phase induction motor in the electrical field, in particular to a guide plate structure (CENTRIFUGAL SWITCH FOR SINGLE PHASE INDUCTION MOTOR) for a centrifugal switch for a single-phase induction motor, in particular to an easy-to-assemble, prevent-zero Centrifugal switches for single-phase induction motors where parts wear out and life is extended. Background technique [0002] Generally speaking, a motor is a device that converts electrical energy into mechanical energy. According to the type of power source used, it can be divided into DC motor and AC motor, and AC motor can be subdivided into induction motor, synchronous motor and commutation motor. [0003] Induction motors can be divided into three-phase induction motors and single-phase induction motors. Among them, single-phase induction motors are widely used in households, offices, industries and agriculture because of their simple structure and firmn...
