Description
Technical field
The utility model relates to a kind of motor, especially relates to a kind of from fanning cooling motor.
Background technology
For the electric drive system that has motor to participate in, all need the speed feedback of motor.Control system is controlled motor by the feedback speed signal receiving and is driven.Resolver, because it is sturdy and durable, reliability is high and resolution is high, can provide high-precision rotor-position signal simultaneously, is used in more and more control precision is required in high electric drive system, is used to provide the speed feedback of motor.
The rotor of resolver and stator need be arranged on respectively rotary part and the static position of motor.And in traditional cooling motor of fan certainly, the rotor of its resolver is fixed in rotating shaft.Because resolver integral installation space requirement is larger, therefore current rotating transformer structures can increase the axial length of motor greatly, thereby increases the volume and weight of motor, to design of electrical motor, brings larger difficulty.Meanwhile, because resolver is arranged on motor internal, it is nearer apart from motor winding, thereby easily produce magnetic field induction, affects output signal of rotary transformer.Also have, resolver is arranged on motor internal, is also unfavorable for safeguarding and debugging.Due to stator and the rotor of resolver, its air gap is less again, mounting process is had relatively high expectations, and can not bear larger impact, vibrations when operation.
Utility model content
For above-mentioned problem, the utility model aims to provide a kind of from fanning cooling motor.It has simple in structure, axial dimension is relatively little, stable output signal, the advantage such as maintain easily.
According to of the present utility model a kind of from fanning cooling motor, comprise rotary main shaft, fan that be fixedly connected with rotary main shaft and that be arranged on motor tail end, the end cap that is arranged on motor tail end, and resolver, resolver comprises stator and rotor, stator is fixedly installed on end cap, and rotor is fixedly installed on fan.This set has avoided rotor to be arranged on rotary main shaft, thereby has reduced axial length, the volume and weight of motor.
Preferably, fan outer rim is provided with for the erecting bed of rotor is installed, and rotor is fixedly connected with erecting bed.This set has been realized rotor has been fixedly mounted on fan.
In one embodiment, rotor utilizes screw to be fixedly connected with erecting bed.Adopt this conventional part of screw, reduced production cost, simultaneously convenient for assembly.
In another embodiment, rotor utilizes shaft block ring to be fixedly connected with erecting bed.
In one embodiment, end cap madial wall week is upwards provided for laying the seam of stator, is provided for the pressing plate of spacing described stator at the first end of seam, and pressing plate is fixedly connected with end cap.In assembling process, stator is arranged in seam, utilize being fixedly connected with of pressing plate and end cap, limit the position of stator.
Preferably, the axial dimension of seam and the axial dimension of stator mate.Therefore, this set has guaranteed spacing to stator of pressing plate.
Preferably, pressing plate utilizes screw to be fixedly connected with end cap.Adopt screw to connect and meet when being fixedly connected with, make simple in structure, convenient for assembly.
First end at rotary main shaft arranges fan pressing plate, and fan is arranged between rotary main shaft and fan pressing plate, utilizes screw that fan pressing plate is fixedly connected with rotary main shaft.By above-mentioned the fixed installation that has realized fan is set.
In this application, described " first end " refers to one end identical with the tail end of motor, and described " axially " refers to the axial identical direction with rotary main shaft.
Compared with prior art, the utility model has the advantage of, because resolver position is at motor afterbody, and its rotor is fixed on fan, and stator is fixed on end cap, can shorten motor axial length, thereby has reduced motor volume, has alleviated motor weight; Simultaneously resolver from motor winding away from, can prevent that motor winding from producing and disturbing signals of rotating transformer, thus stable output signal; Because resolver is contained in motor afterbody, it keeps in repair, debugs equal handled easily, can not affect motor miscellaneous part because of changing resolver; Again because resolver rotor is fixed on fan outer rim, so its stator, rotor diameter are larger, its air gap can be done relatively largely, therefore the antijamming capability of resolver can get a promotion, can in running, bear larger impact, vibrations, and because air gap is larger, relatively low to its matching requirements, more meet engineering demand.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.In the drawings:
Fig. 1 has shown and has certainly fanned cooling motor.
Accompanying drawing is not according to actual scale.
