Abstract
The invention relates to a suction fan cooled open motor. A suction fan is arranged in the internal cavity of the motor and fixed at the rear end of the rotor of the motor, and an air guide plate fixed on an open base is installed behind. The position, which is close to an open front end cap, of the open base is provided with multiple air inlet holes, the internal wall of the open base is provided with a ventilating slot, and the open front end cap is provided with multiple air inlet holes. An open rear end cap is provided with multiple air holes which are circumferentially distributed. When the motor is electrified to rotate, the suction fan rotates along the rotor of the motor, the fan blades suck air from the internal cavity of the motor and discharge air out of the ventilating part of the rear end cap; and the air is sucked into the internal cavity of the motor from the motor shell and the ventilating holes of the front end cap, and the air is compressed by the air guide plate and then flows to the rear cap from the internal part of the suction fan and is discharged out of the motor from the ventilating holes of the rear cap. An effective cooling cycle is formed around the use environment of the motor. Surface temperature of the stator winding and the rotor in operation of the motor can be radiated by rotation of the suction fan so that the motor is enabled to be fully cooled.
Description
Technical field
The present invention relates to a kind of open motor, particularly a kind of fan cold type open motor certainly.
Background technology
Open motor is typically provided with support 11, open-type end cap 10, open-type rear end cap 12, refrigerating fan 13 etc..
As shown in figure 5, existing open motor is usually used general type bleed type aerofoil fan（Fig. 6,7）, it is fixed on motor and turn
Sub 9 front ends or rear end；When electrical power rotates, fan 13 can be followed rotor 9 and be rotated, according to the installation side of fan 13
To motor other end air draft, now fan 13 is the cold air draft of fan in bleed type；Due to there is no good air ducting and structure,
It is easily caused the outer of fan 13 and is with air leakage phenomena, so that blast diminishes, motor can not obtain strong cooling.
Content of the invention
For defect present in above-mentioned prior art, the technical problem to be solved is to provide for a kind of air draught
From fan cold type open motor.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of air draught is electric from fanning cold type open-type
Motivation, including open-type support, open-type drive end bearing bracket, open-type rear end cap, induced draught fan, wind deflector, stator, electric rotating
Son, described induced draught fan is placed in motor cavity, is fixed on rotor rear end, and induced draught fan postpones face equipped with being fixed on out
Open the wind deflector on formula support；Described open-type support is provided with some fresh air inlets, open-type at open-type drive end bearing bracket position
Inboard wall of base carries ventilation slot, and described ventilation slot should be more than stator core external diameter；Described open-type front end be covered with some enter
Air holes；Described open-type rear end is covered with some air holes being circumferentially distributed.
Described induced draught fan has outer ring and inner ring, is provided with blade between outer ring and inner ring.The internal diameter of described wind deflector
It is close with induced draught fan air inlet external diameter.
The invention has the beneficial effects as follows：This motor be provided with open-type support, the forward and backward end cap of open-type, induced draught fan,
Deep bead etc..Induced draught fan is placed in motor cavity, is fixed on rotor rear end；When electrical power rotates, air draught type wind
Fan can follow rotor rotation, due to the special construction of induced draught fan, fan leaf sector-meeting from motor cavity air draught, from rear end
Also place discharges for lid ventilation；Air will suck motor cavity from casing with drive end bearing bracket disposed at air vent, after wind deflector compression, from suction
The inside of wind formula fan flows to bonnet, discharges outside motor from the disposed at air vent of bonnet.Formed around the use environment of motor
One effectively cooling circulation.During the rotation of this induced draught fan, blast is larger, stator winding when can take away motor operation well
With rotor surface temperature, motor is made to be adequately cooled.
