Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-3, a small-sized motor assembly includes:

the motor end cover 1 is arranged on the small motor;

the heat dissipation strip 5 plays the radiating effect, wherein:

two sides of the motor end cover 1 are provided with three first grooves 4, and the heat dissipation strips 5 are fixedly inserted into the first grooves 4;

the ends of the first groove 4 and the heat dissipation bar 5 are both in a "T" shape.

As shown in fig. 2, the wall of the first groove 4 is provided with a ventilation slot 6.

Through adopting above-mentioned scheme, the heat on motor end cover 1 and heat dissipation strip 5 can be taken away to the air that flows in ventilation groove 6, improves the radiating efficiency.

As shown in fig. 3, a gap is left between the end of the heat dissipation strip 5 and the wall of the end of the first groove 4, and the gap between the end of the heat dissipation strip 5 and the first groove 4 is communicated with the ventilation groove 6.

By adopting the scheme, a gap is reserved between the end part of the heat dissipation strip 5 and the first groove 4, so that air in the ventilation groove 6 can flow better.

As shown in fig. 2, a second groove 7 is formed in a wall of the ventilation groove 6 on a side away from the heat dissipation strip 5, and the cross section of the second groove 7 is a semicircular arc.

By adopting the scheme, the contact area between the second groove 7 and the air is increased, and the heat dissipation effect is better.

As shown in fig. 1, a shaft hole 2 is formed in the center of a motor end cover 1, and supporting arm lugs 3 are arranged at four corners of the edge of the motor end cover 1.

Through adopting above-mentioned scheme, utilize the screw to see through the screw hole on the support arm ear 3, can be with this motor end cover 1 fixed mounting on the motor.
