The cooling mode of the low-voltage motor is mainly that the IC411 is cooled by a fan, air is changed by the rotation of the motor to realize cooling, the method can completely meet the cooling energy of a common motor, but the cooling cannot meet the heat generated by the loss of the motor when the individual environmental conditions are poor and the process of the motor has defects. The utility model discloses the constitution includes: the air-conditioning system comprises a motor (1), wherein an air inducing device (3) is fixed on a shell of the motor and comprises a pinch plate (4), an air collecting pipe (5) and an air outlet box (6); the buckle plate is fixed at one end of the air collecting pipe, and the other end of the air collecting pipe is fixed on the air outlet box. The utility model is used for the low-voltage motor cooling.

Description

Low-voltage motor cooling device

Technical Field

The utility model relates to a low-voltage motor cooling device.

Background

As is known, the operation of an electrical machine, i.e. the process of converting electrical energy and mechanical energy into each other, inevitably generates some losses in this process. Most of these losses are converted to heat, which causes the operating temperatures of the motor windings, core and other components to rise. Because the insulation material used by the motor limits the temperature, cooling measures must be taken for the motor, so that the heat generated by the internal loss of the motor is dissipated, and the temperature rise of each part of the motor is maintained within the range specified by the standard. The cooling mode of the low-voltage motor is mainly that the IC411 is cooled by a fan, the cooling is realized by changing air through the rotation of the motor, the cooling energy of the common motor can be completely met by the method, but the cooling cannot meet the heat generated by the loss of the motor when the individual environmental condition is poor and the process of the motor has defects.

Disclosure of Invention

The utility model aims at providing a low-voltage motor cooling device in order to make up the not enough of prior art.

The above purpose is realized by the following technical scheme:

a low-voltage motor cooling apparatus, comprising: the air-conditioner comprises a motor, wherein an air draft device is fixed on a shell of the motor and comprises a pinch plate, an air collecting pipe and an air outlet box;

the buckle plate is fixed at one end of the air collecting pipe, and the other end of the air collecting pipe is fixed on the air outlet box.

In the low-voltage motor cooling device, the air outlet box is a Y-shaped air outlet box, and a plurality of air outlet holes are formed in the arc surface at the bottom of the air outlet box.

Has the advantages that:

1. the utility model discloses be fixed with the induced air ware on the motor winding fin to establish wind channel to motor shaft end with the cooling wind of motor by the air outlet, make the cooling wind energy cool off motor body completely, never reach the effect that improves low-voltage electric machine cooling efficiency.

2. The utility model discloses set up out bellows to it is Y shape to go out bellows, and a plurality of exhaust vents are seted up to its bottom arc surface, can cool off comprehensively to the axle head, improves the cooling effect.
