Abstract
The utility model relates to the technical field of motors, and discloses an asynchronous motor middle plate structure. The asynchronous motor middle plate structure comprises a motor housing and a middle plate. The inner circle of the motor housing is a cylindrical stator space. The middle plate is fixedly arranged in the stator space. The middle plate is used to divide the stator space into two portions. A spindle hole is formed in the middle portion of the middle plate. A plurality of bearing seats are arranged around the spindle hole. An annular groove is arranged in the stator space. A plurality of locating pins are arranged in the annular groove. A plurality of locating grooves are formed in the circumferential surface of the middle plate. After the middle plate is arranged in the annular groove, the locating pin cooperates with the locating groove to fix the middle plate. According to the utility model, structures, such as the bearing seats, etc., are directly arranged on the middle plate, so the subsequent installation steps of parts can be reduced, the accuracy can be improved, and through the through hole in the middle plate, not only the weight of the middle plate can be reduced, and the consumption of raw materials can be reduced.
Description
Technical field
The utility model relates to motor technology field, relates in particular to a kind of middle plate structure of asynchronous machine.
Background technology
Asynchronous motor claims again induction motor, is to be interacted and produced electromagnetic torque by air-gap rotating magnetic field and rotor winding induced current, thereby realizes a kind of alternating current machine that energy converting between mechanical is mechanical energy.Asynchronous motor is divided into two kinds of forms according to rotor structure: have squirrel-cage and wire wound asynchronous motor.Make the asynchronous machine of motor operation.Because its rotor winding current is that induction produces, claim again induction motor.Asynchronous motor be most widely used in all kinds of motor, that requirement is maximum is a kind of.Take in the machinery that electricity is power of various countries, approximately having 90% left and right is asynchronous motor, its small and middle induction motors accounts for more than 70%.In the total load of electric power system, the power consumption of asynchronous motor accounts for sizable proportion.In China, the power consumption of asynchronous motor accounts for more than 60% of total load.In band, the different motor of plate can be realized the acting in conjunction of two groups of rotors by middle plate, realizes effective output of power.
Referring to accompanying drawing 1, the middle plate of existing asynchronous machine is disk-like structure, when practical application, also will assemble different parts and realize its function, and dish assembling structure weight is large, and cost is high.
