Abstract
The utility model relates to an external rotor type brushless DC motor for vehicle power, which comprises a motor shaft. The motor shaft is provided with a bearing. The bearing is provided with a stator rack where a stator is disposed. The external part of the stator is a rotor which is fixedly connected with the motor shaft. The bottom of the stator rack is provided with a position feedback component. Compact in structure, safe and reliable to operate, the motor is also convenient to maintain, easy to mount and suitable to be produced in batches.
Description
Technical field:
The utility model relates to Vehicular direct-current technical field of motors, is specifically related to a kind of vehicle-mounted power external-rotor-type brushless DC motor.
Background technology:
Existing external rotor brushless DC motor mostly is traditional cantilever design, motor is made up of parts such as rotor, stator, motor shafts, the fastening one of motor shaft and stator is as the support of complete machine, rotor yoke one side leaves the installation of bearing chamber for bearing, refill and be placed in rotor driven partial rotation on motor shaft, together with stator is fastening with axle, install basic by fixed electrical machinery axle two ends, mounting means is more single, is not easy to large-scale promotion and uses.Meanwhile, rotor portion, by single-cantilever version, easily causes the phenomenons such as motor oscillating abnormal sound, bearing damage, requires machining accuracy high, and the dynamic resonance analysis of Standard is correct, and these all bring a lot of difficult problems to manufacturing and designing of motor.
Utility model content:
The purpose of this utility model is to provide a kind of vehicle-mounted power external-rotor-type brushless DC motor, its compact conformation, and security of operation, reliable, operating maintenance is convenient, and assembling simple possible, is applicable to batch production.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: a kind of vehicle-mounted power external-rotor-type brushless DC motor, comprise motor shaft, described motor shaft is provided with bearing, described bearing is provided with stator support, described stator support is provided with stator, and described stator outside is provided with rotor, and described rotor is fixedly connected with motor shaft; Described stator support bottom is provided with position feedback assembly.
Further concrete, described motor the tip of the axis is provided with transducer magnet steel.
Further concrete, described stator support is provided with hole and line outlet groove.
The utlity model has following beneficial effect: compact conformation, can effectively utilize locus, change single-cantilever structure, improve the Stability and dependability of motor operation.The installation form that is effectively utilized as motor of stator support structure provides variation, is convenient to the use of every field external rotor electric machine.In addition, motor simple in structure, maintenance convenient for assembly, is applicable to batch production.
Brief description of the drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: a kind of vehicle-mounted power external-rotor-type brushless DC motor, comprise motor shaft 6, described motor shaft 6 is provided with bearing 8, described bearing 8 is provided with stator support 2, described stator support 2 is provided with stator 5, and described stator 5 outsides are provided with rotor 7, and described rotor 7 is fixedly connected with motor shaft 6; Described stator support 2 bottoms are provided with position feedback assembly 1; The end of described motor shaft 6 is provided with transducer magnet steel 3; Described stator support 2 is provided with hole and line outlet groove.
This embodiment operation principle: by bearing 4 and bearing 8 inner support motor shafts 6, rotor driven 7 parts are steadily rotated, position feedback assembly 1 is installed on stator support rear end, sample from motor shaft tip sensor magnet steel 3, for motor feedback position signal, stator support 2 rear ends can be according to interface requirements, adopts form and the assembling of other parts in axle or hole.
This embodiment has following beneficial effect: compact conformation, can effectively utilize locus, and change single-cantilever structure, improve the Stability and dependability of motor operation.The installation form that is effectively utilized as motor of stator support structure provides variation, is convenient to the use of every field external rotor electric machine.In addition, motor simple in structure, maintenance convenient for assembly, is applicable to batch production.
