Description
Technical field
The utility model relates to a kind of electric machine stand of brushless dual-feed motor, belongs to the technical field of motors of brushless dual-feed motor.
Background technology
The support mainly flange-cooled version of double feedback electric engine in the market, which is applicable to the draft type of IP44, heat drains on inboard wall of base by internal fan by the heat that namely motor produces, heat is drained into external by fin again, the double feedback electric engine of not speed change uses this support to be feasible.But the brushless dual-feed motor of our factory research and development is variable-speed operations, when motor speed declines, the power of motor is still very large, the heat produced in motor is caused to gather increase like this, now the rotating speed of internal fan declines along with motor speed and declines, the abatement of wind, if use flange-cooled support, radiating effect is very poor.Therefore, how the draft type of support designs the wind path that inner loop wind path could be changed into axial ventilation, solves heat radiation contradiction during brushless dual-feed motor variable-speed operation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides the electric machine stand that a kind of good heat dissipation effect, compact conformation, volume are little, meet the high brushless dual-feed motor of power of motor density.
For achieving the above object, the technical scheme of the utility model sampling is: the electric machine stand of a kind of brushless dual-feed motor of the present utility model comprises machine base body, front end face, rear end face, machine base body is the cylinder of hollow, the front end face of machine base body is provided with joint hinge hole before two symmetries, rear end face is provided with joint hinge hole after two symmetries, on front end face, endoporus stretches a front boss, rear end face endoporus stretches a rear boss, for installing end cap, in the machine base body of closing on front end face, two symmetrical square Inner eycle ventilating openings are established in the left and right sides, two square Inner eycle ventilating opening peripheries outwards have ventilating opening boss, machine base body top rear establishes air inlet of centrifugal fan, terminal box is established in front side, the axial spoke muscle of the six roots of sensation is established in machine base body inside, upper and lower four spoke muscle all connect front/rear end, the two spoke muscle in left and right only connect rear end face and Inner eycle ventilating opening edge.
Width S=the 30mm of described front boss and rear boss.
The axial spoke muscle equal circumference angle of the described six roots of sensation is evenly distributed on machine base body inwall, and the height of spoke muscle is identical with the height of rear boss with front boss, is 36 ~ 37mm, the wide H=60mm of spoke muscle; It is interior air duct between spoke muscle.
Described machine base body outer surface is provided with axial support bar.
The utility model has the following advantages:
1, respectively to stretch a boss at the front end face of machine base body and rear end face, add the rigidity of whole support;
2, left and right Inner eycle ventilating opening, for motor provides circulation canal, can help motor radiating better, the desirable high value of heat load of motor, thus improves the power density of motor;
3, six roots of sensation spoke muscle is evenly distributed on inboard wall of base, can base frame stiffness be increased, be beneficial to again stator core and winding overhang heat radiation, because stator core cylindrical is equal with spoke muscle inner circle, after such press-in iron core by it with machine base body every sky, thus the air channel that ventilates in forming with ventilating opening;
4, air inlet of centrifugal fan is located on rear side of support, thus can well cold wind water conservancy diversion be gone over, and reduces iron core and the winding overhang temperature of motor;
5, machine base body outer surface is provided with support bar, the lead-in wire of rigid bearing temperature element on support bar, and lead-in wire can be avoided to be scattered and to damage, and extends device useful life.
