Motor

Abstract

The invention relates to a motor, which comprises a shell, a base, a rear end cover, a stator and a rotor, wherein the stator and the rotor are accommodated in the shell; the rear end cover is fixedly connected with the rear end of the shell to close the rear end of the shell; the base comprises bottom studs and a connecting plate; the connecting plate is vertical to the axis of the motor and is fixedly connected with the front end of the shell; the connecting plate has shaft holes; a bearing is arranged at the position of the shaft hole on the rear side of the connecting plate; the rear end cover also has a rear shaft hole, and a bearing is also arranged on the inner side of the position of the rear shaft hole; and the rotating shafts on two ends of the rotor passes through the bearing and rear holes on the connecting plate and the rear end cover respectively. The shell of the motor has a high bearing capacity; the motor and the base are reliably connected; and the structure is simple. The motor has the characteristics of small volume, desirable radiation and large output torque.

Description

technical field [0001] The invention relates to an electric machine. Background technique [0002] Motors are common equipment in daily industry and daily life. The current motors mainly include shells, bases, front covers, rear covers, stators and rotors. Now many motors use aluminum shells to improve the heat dissipation performance of the motors. Aluminum Although the shell is light in weight and good in heat dissipation, it is soft in texture. Since the base is directly fixed on the lower part of the outer surface of the aluminum shell, the connection between the base and the aluminum shell, which is the main support point of the motor, will be damaged when the load is heavy. Therefore, the motor with aluminum shell cannot be used in high-power and high-load motors, while the motor with cast iron shell is heavy and has poor heat dissipation, and the shell will still appear under high load conditions. body deformation.
