Abstract

The invention relates to a motor. The motor comprises a stator component, a rotor component, end covers and a shell, wherein the stator component and the rotor component are arranged in the shell; the end covers are arranged at the two ends of the shell; a rotating shaft of the motor is supported on bearing chambers of the end covers through bearings; a plurality of plug holes are reserved on the side wall surfaces, close to the end covers, of the shell along the circumference; plug pieces are arranged on the plug holes; the plug pieces comprise plug parts and support parts; the plug parts are buckled into the plug holes; the support parts are closely adhered to the outer wall surface of the shell; screw holes are reserved on the plug parts; mounting holes corresponding to the positions of the screw holes are reserved on the end covers; and bolts pass through the mounting holes and are screwed into the screw holes of the plugs parts to lock the shell with the end covers. In the motor, by configuring special plug pieces and bolts, the shell and the end covers are locked together without any contact to the stator component in the motor or influencing the electromagnetic performance of a motor stator winding; the motor is convenient to install and position; the assembly efficiency is high; the structure strength is high; and the stability and the reliability are high.

Description

Technical field: [0001] The invention relates to an electric machine. Background technique: [0002] At present, the vast majority of drum motors still directly adopt the traditional connection structure - through the bolt and nut mechanism passing through the front and rear end covers of the motor and the stator yoke, the motor armature assembly, the casing and the front and rear end covers are connected together. The use of this installation structure causes the bolts to occupy the space of the stator yoke, which will adversely affect the electromagnetic performance of the motor stator assembly, and is limited by the internal space structure of the motor, making installation and positioning difficult, installation accuracy difficult to guarantee, and assembly efficiency low. In addition, there are common problems such as insufficient connection structure strength and poor heat dissipation effect of the whole machine. [0003] With the rapid development of motor technology...
