Abstract

The invention relates to an efficient air cooling structure applied to a motor. The efficient air cooling structure comprises a shell, a stator fixedly arranged in the shell, a front end plate and a rear end plate which are connected to the two ends of the shell, and a rotor coaxially arranged in the stator. The front end of a rotating shaft of the rotor penetrates through the front end plate and extends out of the shell, and the rear end of the rotating shaft penetrates through the rear end plate and extends out of the shell. A plurality of cooling fins with n-shaped or inverted-V-shaped sections are evenly distributed on the outer wall of the shell in the circumferential direction, the two sides of each cooling fin are welded to the outer wall of the shell in a sealing mode respectively, and any cooling fin and the shell form an air channel. The rear end of the rotating shaft is fixedly connected with a fan located outside the shell, and the outer edge of the rear end of the shell is connected with a protective cover covering the fan. A large number of air holes are formed in the rear end of the protective cover, and the protective cover is connected with the rear end of the shell through an annular connecting plate. The front end of the connecting plate is welded to the rear end face of the shell and the rear end faces of the cooling fins. The front end of the protective cover is welded to the outer edge of the rear end of the connecting plate. Through holes in one-to-one correspondence with the air channels are formed in the connecting plate.

Description

technical field [0001] The invention relates to a high-efficiency air-cooling structure applied to a motor. Background technique [0002] The motor and its servo system are widely used in the fields of industrial drive and servo control because of their small size, high efficiency, and good dynamic response characteristics. When the frequency converter controls the motor to operate with variable frequency, the operating frequency of the motor changes at a frequency of 50 Hz or below, and the speed of the motor corresponds to its frequency. [0003] However, the built-in cooling fan of the motor will also change with the speed of the motor, and the exhaust air volume of the motor will also change accordingly. When the motor is running at low frequency, the speed of the motor is low, and the speed of the fan is also low. As a result, the flow rate of the cooling airflow used to cool the motor decreases, which in turn causes the cooling airflow to spread radially outward along...
