Abstract

The present invention discloses a polygon prism motor cylindrical shell. The motor cylindrical shell is provided with a cavity, a hood connection piece is arranged at the outer surface of the motor cylindrical shell, and the outer contour of the motor cylindrical shell is a polygon prism. The outer contour of the cross section of the motor cylindrical shell is a polygon, the machinery performance and the rigidity of the motor cylindrical shell are obviously improved and the production is easy. Compared with the thickness increasing of the shell, the consumption of the shell materials is decreased, and the production cost is reduced. When the motor cylindrical shell is fixed at the inner wall of the device, thermal conduction happens between the shell and the fixed surface so as to ensure the thermal conductivity of the motor cylindrical shell.

Description

technical field [0001] The invention relates to the electromechanical field, in particular to a polygonal column motor casing. Background technique [0002] The heat energy generated by the stator and rotor in the motor is transferred to the casing through heat conduction, and dissipated into air, water, oil and other fluids in the form of heat radiation. In the prior art, aluminum is usually selected as the housing material of the motor, because aluminum has low density, excellent thermal conductivity, convenient processing and manufacturing, and low cost. However, the mechanical strength of aluminum is significantly lower than that of other metals such as cast iron, which cannot meet the requirements of motors with a higher center height. In the prior art, the method of increasing the wall thickness of the motor casing is generally used to improve the mechanical strength, but this will reduce the heat dissipation performance of the casing, and at the same time increase th...
