Variable-frequency integrated three-phase asynchronous motor

Abstract

The invention discloses a frequency conversion integrated three-phase asynchronous motor, which comprises a motor body, a frequency converter and a motor cooling device, and is characterized in that the motor body and the frequency converter are connected through a dismounting and mounting structure; an input end wiring terminal frame is arranged on the motor body, a frequency converter is fixedly installed in the input end wiring terminal frame through a detachable installation structure, the detachable installation structure comprises an installation block and a fixing column which are fixedly installed in the input end wiring terminal frame, and the outer side of the fixing column is sleeved with a supporting spring; the dismounting and mounting structure further comprises fixing sleeves arranged at the bottoms of the front side face and the rear side face of the frequency converter, guide blocks are fixedly mounted on the left side and the right side of each fixing sleeve, spring grooves are formed in the guide blocks, and positioning pins penetrate through the guide blocks and extend into inner cavities of the fixing sleeves. The frequency converter is convenient to dismount through the dismounting and mounting structure; the motor cooling device improves the heat dissipation performance of the motor body and prolongs the service life of the motor; the arrangement of the wire storage box body avoids the disordered wiring of the motor and the frequency converter, and the frequency converter can be dismounted for inspection and maintenance without dismounting a wire.

Description

technical field [0001] The invention relates to the technical field of frequency conversion motors, in particular to a frequency conversion integrated three-phase asynchronous motor. Background technique [0002] Frequency conversion motor referred to as frequency conversion motor is a general term for motors driven by frequency converters. The motors can achieve different speeds and torques under the drive of frequency converters to adapt to changes in load demand; the existing frequency conversion motors are used in harsh environments and dissipate heat. In poor conditions, variable frequency motors often fail due to high operating temperature for a long time; and for variable frequency integrated three-phase asynchronous motors, since the frequency converter is directly fixed on the motor body, when the frequency converter fails, the frequency converter needs to be disassembled. Maintenance, the traditional bolt installation method, the bolts are easy to rust when used fo...
