Description

Technical Field

[0001] The utility model belongs to the technical field of electric motors, and more specifically relates to an electric motor housing which is easy to dissipate heat. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses the principle of electromagnetic induction to form electromagnetic torque. The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the current-carrying conductor in the magnetic field is related to the direction of the current and the magnetic flux lines (direction of the magnetic field). The working principle of the electric motor is that the magnetic field acts on the force of the current, causing the motor to rotate. Electric motors play a vital role in people's production and life.

[0003] Electric motors often need to be equipped with motor casings during use. The motor casing is mainly used to concentrate the internal components of the motor and provide protection. At the same time, during the installation of the motor, it is also necessary to assemble and fix the motor with external equipment through the motor casing. However, since the holes of the mounting plate on the motor casing are fixed in position, the hole positions of the mounting plate may deviate from the positions of the mounting holes on some equipment when the motor casing is installed with external equipment, thereby affecting the assembly of the motor with the external equipment. Utility Model Content

[0004] The main purpose of the utility model is to provide a motor housing which is easy to dissipate heat.

When the circular hole block moves to the position where the inner wall coincides with the inner wall of the mounting hole on the external device, the screw hole ring is manually rotated to make the screw hole ring move left and right along the surface of the screw. When the screw hole ring moves to the position of extruding the surface of the rectangular frame, the position of the circular hole block is fixed. At this time, the personnel screws into the mounting holes of the circular hole block and the external device through tools to fix the rectangular frame, thereby achieving the fixation of the base and the shell, reducing the situation where the shell cannot be installed and fixed with the equipment due to the incompatibility of the hole position during installation, and improving the convenience and flexibility of personnel in installing the shell.
