Description

A structure for simultaneously dissipating heat from the motor and the controller

technical field

The utility model relates to the technical field of motor cooling, in particular to a structure for simultaneously cooling a motor and a controller.

Background technique

Understanding: The main ways for the motor to dissipate heat are: natural cooling through air convection and radiation cooling; fan on the rotor blowing heat to dissipate heat; cooling teeth of the motor housing to dissipate heat.

However, the existing motor can only dissipate heat inside the motor, but cannot dissipate heat from the controller and driver on the outer casing.

However, most of the existing motor casings are single-walled, and the built-in fan can only dissipate heat from the inside of the motor, but cannot dissipate heat from the external controller.

There are also air ducts on the inner wall of some motor casings, but the fan is placed inside the motor, and the air ducts mainly provide heat dissipation for the motor body.

Retrieval: Search the relevant field in the patent database, and a total of hundreds of related patents have been retrieved, of which the following two are relatively similar to the technical problems solved by this application.

Citation: For the utility model patent with the patent number of 202120390269.0, a servo motor housing that is convenient for heat dissipation is disclosed, including the main body of the motor housing. One end of the main body of the motor housing is provided with a front cover mechanism. A heat dissipation mechanism is arranged between them, and an output shaft is connected to the internal rotation of the main body of the motor casing. The beneficial effect of the utility model is that the airflow blown by the fan blades can dissipate heat on the main body of the motor casing, so that the gas on the outer surface of the main body of the motor casing can circulate. , to facilitate heat dissipation, the output shaft drives the second gear to rotate, the second gear drives the first gear to rotate, the inner gear ring of the first gear rotates, the inner gear ring drives the outer ring of the wide-diameter bearing to rotate, and the outer ring of the wide-diameter bearing drives the fan blade When assembling the cooling mechanism, insert the plug into the slot first, then close the main body of the front cover, the main body of the front cover is against the inner ring of the wide-diameter bearing, and finally fix the main body of the front cover with bolts. It is very convenient to install.

Summary: For this related patent, the inventor thinks that this patent dissipates heat from the main body of the motor casing through the airflow blown by the fan blades, which is convenient for heat dissipation, but its structure is relatively complicated, and it can only dissipate heat from the inside, but cannot dissipate heat from the outside .

Citation: For the invention patent with the patent number of 201711093916.6, an energy-saving heat-dissipating motor is disclosed, including a motor casing, a rotor is interspersed on the motor casing, and a ventilation sleeve is fixedly connected to one side of the motor casing. And there are two first driving wheels sleeved on the outside of the motor casing, the first driving wheels are connected to the first driven wheel through the first belt, the first driven wheel is sleeved with a rotating rod, and the two One end of the rotating rod respectively penetrates the upper and lower sides of the motor casing and extends into the ventilation sleeve, and three ventilation openings are opened at equal distances from the top and bottom of the motor casing. In the present invention, through the improvement of the first fan blade, the rotor cooperates with the use of the driving bevel gear and the driven bevel gear to drive the first fan blade to rotate, so that the kinetic energy of the motor itself can be used to dissipate heat, and the effect of energy saving and heat dissipation can be achieved. The second driving wheel and the second driven wheel drive the movable rod to rotate, so that the second fan blade on the movable rod will rotate accordingly.

Summary: For this related patent, the inventor thinks that although this patent achieves internal heat dissipation, the patent is equipped with a large number of transmission fans and transmission mechanisms to achieve heat dissipation on the side wall, which has a complex structure and relatively high cost. High, the transmission of parts is easy to be damaged.

On this basis, the utility model provides a structure for simultaneously dissipating heat from the motor and the controller to solve this problem.
