Abstract
The utility model relates to a motor, and especially relates to a frequency-converting speed-regulating motor comprising a housing, a front end cover, a back end cover, a main shaft, a stator and a rotor, wherein the stator is fixed on an inner wall of the housing, the rotor is fixedly connected on the main shaft, the stator surrounds the rotor, the back end cover is provided with a fan housing, the fan housing is provided with a fan therein, and the fan is fixedly connected on the fan housing. The frequency-converting speed-regulating motor of the utility model may not increase a running resistance of the main shaft of the motor, and the main shaft of the motor can have a good heat dissipation effect either at a normal speed or at a low rotation speed.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of frequency control motor.
Background technology
Variable-frequency motor is compared with common electric machine, and mechanical automation degree and production efficiency all improve a lot.Therefore the use of variable-frequency motor more and more widely.During the variable-frequency motor operation, inner meeting produces great amount of heat, if heat is excessive; Will burn out the coil of variable-frequency motor; Therefore fan all can be installed to dispel the heat on the variable-frequency motor, the fan of the normal variable-frequency motor that uses all is installed on the motor shaft on the market, when motor shaft rotates; Fan is rotation thereupon also, thereby variable-frequency motor is dispelled the heat.But fan directly is contained on the motor shaft running resistance that can increase motor shaft, even fan can not reach the purpose of cooling when the motor shaft low speed rotation.
The utility model content
The utility model increases the running resistance of motor shaft to existing fan, the problem of fan weak heat-dissipating during the motor shaft low speed rotation, and providing a kind of can not increase the motor shaft running resistance, and the good frequency control motor of radiating effect during the motor shaft low speed rotation.
The purpose of the utility model realizes through following technical proposals: a kind of frequency control motor; Comprise housing, front end housing, rear end cap, main shaft, stator and rotor, said stator is fixed on the inwall of housing, and rotor is fixedly connected on the main shaft; Track ring is around in peritrochanteric; On the said rear end cap fan housing is installed, is provided with blower fan in the said fan housing, said blower fan is fixedly connected on the fan housing.
Adopt this programme; In the fan housing of on rear end cap, installing blower fan is set, and blower fan is fixedly connected on the fan housing, blower fan just can be independent of the variable-frequency motor main shaft like this; Needn't be again rotation through electric machine main shaft drive the fan rotation, eliminated fan and be installed in the running resistance on the electric machine main shaft.When variable-frequency motor was worked, the independent blower fan that is provided with promptly can force cooling to motor, even when the electric machine main shaft low speed rotation, still have better heat radiating effect, had effectively protected motor can not prolong the useful life of motor because of overheated and burn out.
As preferably, between described rear end cap and the described blower fan brake that main shaft is stopped operating is installed, said brake passes through bolt on rear end cap.The brake that fixed installation stops operating main shaft on rear end cap is made as one with brake and variable-frequency motor like this, does not need special brake apparatus, can realize the braking to variable-frequency motor, has reduced production cost.Simultaneously brake is arranged between rear end cap and the blower fan, blower fan both can be protected motor like this, can protect brake again.
Therefore, the beneficial effect of the utility model is: can not increase the running resistance of electric machine main shaft, no matter and motor shaft radiating effect when normal speed or low speed rotation all better.

Fig. 1 is the structural representation of the utility model.
Illustrate: 1-housing, 2-front end housing, 3-rear end cap, 4-main shaft, 5-stator, 6-rotor, 7-fan housing, 8-blower fan, 9-brake.
Embodiment
A kind of frequency control motor; Comprise housing 1, front end housing 2, rear end cap 3, main shaft 4, stator 5 and rotor 6, said stator 5 is fixed on the inwall of housing 1, and rotor 6 is fixedly connected on the main shaft 4; Stator 5 is surrounded on around the rotor 6; On the said rear end cap 3 fan housing 7 is installed, is provided with blower fan 8 in the said fan housing 7, said blower fan 8 is fixedly connected on the fan housing 7.The brake 9 that main shaft is stopped operating is installed between described rear end cap 3 and the described blower fan 8, and said brake 9 passes through bolt on rear end cap 3.
Adopt this programme; In the fan housing of on rear end cap 3, installing 7 blower fan 8 is set; And blower fan 8 is fixedly connected on the fan housing 7; Blower fan 8 just can be independent of variable-frequency motor main shaft 4 like this, needn't be again rotation through electric machine main shaft 4 drive the fan rotation, eliminated fan and be installed in the running resistance on the electric machine main shaft 4.When variable-frequency motor is worked; The independent blower fan 8 that is provided with promptly can force cooling to motor; Even when electric machine main shaft 4 low speed rotation, still have better heat radiating effect, effectively protected motor can not prolong the useful life of motor because of overheated and burn out.The brake 9 that fixed installation stops operating main shaft 4 on rear end cap 3 simultaneously is made as one with brake 9 and variable-frequency motor like this, does not need special brake apparatus, can realize the braking to variable-frequency motor, has reduced production cost.
Claims (2)
