Description
Technical field
The utility model is related to a kind of magneto field, especially a kind of automotive window permanent-magnet brushless DC electric machine.
Background technology
In present automobile industry, automobile window glass electric up-down has become standard configuration.Automotive window is exactly to drive with motor
The power source of dynamic glass-frame riser.The quality and controllability of motor performance decide the stability of automobile window glass lifting work
And safety.
Automotive window is substantially permanent-magnet DC brush motor with motor at present, brush motor there is many drawbacks, by
In the presence for having brush-commutated device, there may be electric spark, short lifes, while this brush motor volume is big, weight is big and imitates
Rate is very low, generally only between 20%-40%.However, present permanent-magnet brushless DC electric machine technology comparative maturity, no matter
There are good development, this electric efficiency that can be up to 90% in terms of being in terms of the Design of Mechanical Structure or electronic controller
Above and long lifespan, small, weight is small, performance well equal many-sided advantage.
Invention content
The purpose of this utility model provides a kind of automotive window permanent-magnet brushless DC electric machine.The skill that the utility model solves
Art problem is ensuring that under the requirement of the operation is stable, provides on a kind of stator with installation sensor support frame and stepped rotor
The permanent-magnet brushless DC electric machine of axis, than conventional car window electric efficiency higher, volume smaller, weight is lighter.
In order to achieve the above objectives, the utility model adopts the following technical solution：A kind of automotive window DC permanent-magnetic brushless
Motor, including stationary part and rotor portion, it is characterised in that the stationary part includes：Stator core (4), mounting plate
(1), supporting rack (2), the rotor portion include：Rotor core (7), permanent magnet (3), clamp spring (6)；The stator core
(7) it is to be formed using silicon steel plate stacking, there is a groove (11) in upper surface, for installing supporting rack (2), the supporting rack
(2) change material is a kind of high-temperature resistance plastice, and hollow cylinder, thickness 2mm, there are 9 rectangular channels (10) in outer surface, are used for line
The cross-slot connection of (5) is enclosed, there be 3 cylinder steps (9) end face thereon, is used for fixed mounting plate (1), the mounting plate (1)
It is fixed that there are three cylinder steps (9) on location hole (8), with supporting rack (2), and 3 sensors and connection line, institute are installed in surface
The rotor core (7) stated is a multi-diameter shaft, lower surface of the cylinder step (13) for positioning permanent magnet (3) thereon, described
Permanent magnet (3) be surface-mount type circular ring shape, jump-ring slot rotor core (7) on fixed using high-temp glue and rotor core (7)
(12) it is used for the upper surface of fixed permanent magnet (3), prevents from being axially moved.
The utility model proposes automotive window be with permanent-magnet brushless DC electric machine beneficial outcomes：Devise a kind of rotor iron
Core multi-diameter shaft so that round ring magnet installs accurate positioning with rotor surface, simple and convenient；It devises a kind of mounted on stator
The supporting rack of iron core so that sensor is separately installed with stator punching, is convenient for installation, the repair and replacement of sensor；This practicality is new
Automotive window described in type compared with traditional vehicle window permanent-magnet DC brush motor with power, is imitated with permanent-magnet brushless DC electric machine
Rate is high by 40% or so, and volume and weight also only has 75% or so of original motor, power density greatly improves, simultaneously because not having
There is the friction electric spark of brush and commutator, also more long, structure is also simpler for service life, and manufacture is easy to assembly.
