Novel air compressor asynchronous motor

Abstract

The invention relates to a vehicle-use air compressor variable frequency asynchronous motor, in particular to a novel air compressor asynchronous motor, which solves the problems of poor use effect and short service life of the air compressor motor, caused by unreasonable internal structure design of the existing air compressor motor. The novel air compressor asynchronous motor comprises a machine seat, a stator iron core, a stator coil and a rotor, wherein the stator iron core is fastened by a stator press ring and a buckle sheet, a stop opening positioning step matched with the stator iron core is arranged on the inner surface of the machine seat, one end of the stator iron core, fastened by the stator press ring and the buckle sheet, is positioned at the stop opening positioning step, the other end of the stator iron core is welded on the machine seat, a groove used for fastening and connecting the buckle sheet is uniformly arranged on the outer end surface of the stator press ring, the buckle sheet is buckled in the groove, and the stator coil has three turns at the head part and the tail part, and is additionally sheathed with fiber glass sleeve pipes. The invention can better adapt to the special use requirements of the air compressor motor, and can meet the requirements of frequent starting, large motor overload times, small size and good heat radiation effect of the air compressor motor.

Description

technical field [0001] The invention relates to a frequency-variable asynchronous motor for an air compressor used in locomotives, in particular to a novel asynchronous motor for an air compressor. Background technique [0002] Due to the limitation of the application field of the air compressor motor in the existing locomotive air compressor, the structure and working characteristics of the air compressor motor have special requirements: the starting performance of the air compressor motor must be able to meet the requirements of frequent starting Requirements, and require the motor to have a large overload multiple, small size, and good heat dissipation. [0003] At present, in the frequency conversion asynchronous motors used in locomotive air compressors, the stator core is generally fastened axially through the buckle and spot welded firmly, and then shrunk onto the machine base. The stator core and the machine base are fixed by spot welding; the stator core is fixed by...

Problems solved by technology

[0008] In order to solve the problems of unreasonable design of the internal structure of the frequency conversion asynchronous motor of the existing air compressor used in locomotives, resulting in poor use effect and short service life of the air compressor motor, the present invention specifically relates to inaccurate positioning of the stator core of the motor and the initial positioning of the stator coil. To solve the problem that the last three turns are easy to age, a new type of asynchronous motor for air compressors is provided
