Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1 and 2, the utility model provides an air cooling motor, including motor body 1, housing 2 and radiator fan 3, housing 2 is the tube-shape, housing 2 cover is in outside motor body 1, and with motor body 1 is connected fixedly, housing 2 with the clearance has between motor body 1, radiator fan 3 installs on housing 2, and its flabellum 301 is located in the clearance.

A plurality of cushion blocks 101 are arranged in a gap between the motor body 1 and the housing at intervals, the cushion blocks 101 are fixedly connected with the motor body 1, the housing 2 is supported outside the motor body, and the housing 2 is fixed on the cushion blocks 101 through screws.

The side wall of the housing 2 protrudes outwards, a groove 201 is formed at the position of the protruding part inside the housing 2, the heat dissipation fan 3 is installed at the protruding part, and the fan blades 301 are located in the groove 201.

The rear end of the housing 2 is close to the rear end of the motor body 1, and the front section of the housing 2 is located in the middle of the motor body 1.

The motor further comprises a handle 4, and the handle 4 is mounted on the front section of the motor body 1 and/or the housing 2.

The handle 4 is n-shaped, one end of the handle 4 is fixedly connected with the front section of the motor body 1, and the other end of the handle 4 is fixedly connected with the housing 2.

The number of the handles 4 is two, and the two handles 4 are respectively arranged on two sides of the motor body 1 and the housing 2.

As shown in fig. 3, the cooling fan further comprises a temperature sensor 5 and a controller 6 (a single chip microcomputer stm32 series single chip microcomputer can be adopted), the temperature sensor 5 is arranged on the shell of the motor body 1, the cooling fan 3 and the temperature sensor 5 are both electrically connected with the controller 6, and the controller is externally connected with a power supply to supply power to the cooling fan. The controller may be integrated within the enclosure.

Therefore, a temperature threshold value can be set through the controller, if the temperature sensor senses that the temperature of the surface of the motor body is higher than the threshold value (the threshold value is a range according to the sensitivity or the error of the temperature sensor, but not a point value, if the threshold value can be set to be 70 ℃, but is specifically understood to be a range value around 70 ℃), the controller controls the cooling fan to start to dissipate heat, and if the temperature sensor senses that the temperature of the surface of the motor body is lower than the threshold value, the controller controls the cooling fan to stop running.
