Scooter integrated brushless DC motor device
Technical field:
The used for vehicle Power Drive Unit that the present invention relates to lie fallow, is specifically related to a kind of scooter integrated brushless DC motor device.
Background technology:
The existing drive system that is applied to this field, motor and controller are split type, and motor is traditional inner rotor core, is partly comprised of front and rear cover, casing, rotor, position feedback etc., controller and motor are by connector and cable transmission power and signal; The shortcoming of this kind of structure is that to take the volumetric spaces of car load large, gains in weight, and has reduced course continuation mileage, and the connection of cable simultaneously affects car load outward appearance, and signal is easily influenced.
Summary of the invention:
The object of this invention is to provide a kind of scooter integrated brushless DC motor device, it is made of one motor and controller, makes compact conformation, reliable, and operating maintenance is convenient.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: scooter integrated brushless DC motor device, described device comprises motor shaft, described motor shaft is provided with bearing, on described bearing, be fixed with stator support, described stator support is provided with stator, in the outside of described stator, is provided with rotor, and described rotor and motor shaft are fastenedly connected; The side of described stator support is provided with position feedback assembly; Side at described position feedback assembly is provided with controller radiator, and a side of described controller radiator is provided with power model and control module; Described power model and control module are connected with plug connector.
Further concrete, described stator support rear end is provided with the screw hole for being connected with controller radiator.
Further concrete, described functional module is close on controller radiator.
Further concrete, described controller radiator and stator support are provided with wire hole.
Further concrete, described device is provided with for fixing ring flange.
The present invention has following beneficial effect: it reduces weight and the volumetric spaces of car load by the design of integral structure, has increased car load course continuation mileage, by ring flange, is facilitated with car load and is installed.In addition, the appropriate design of electric system electromagnetic circuit, has improved the power density ratio of motor, has increased motor overload ability, meets car load in the operation of various road conditions, reaches energy-efficient object.Meanwhile, the ingenious layout of structure has also facilitated the installation and maintenance of electric system, is applicable in enormous quantities, machineization production.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: scooter integrated brushless DC motor device, described device comprises motor shaft 3, described motor shaft 3 is provided with bearing 4, on described bearing 4, be fixed with stator support 5, described stator support 5 is provided with stator 2, in the outside of described stator 2, is provided with rotor 1, and described rotor 1 is fastenedly connected with motor shaft 3; The side of described stator support 5 is provided with position feedback assembly 6; Side at described position feedback assembly 6 is provided with controller radiator 7, and a side of described controller radiator 7 is provided with power model 8 and control module 10; Described power model 8 and control module 10 are connected with plug connector 9; Described stator support 5 rear ends are provided with the screw hole for being connected with controller radiator 7; Described functional module 8 is close on controller radiator 7; Described controller radiator 7 and stator support 5 are provided with wire hole; Described device is provided with for fixing ring flange.
During the assembling of this embodiment, rotor 1 and motor shaft 3 are fastenedly connected to composition rotating part, then stator 2, position feedback assembly 6, bearing 4 are fixed on stator support 5, by bearing 4 inner support motor shafts 3, form motor body structure.Screw hole is left in stator support 5 rear ends, is connected by screw controller radiator 7, and power model 8 is close to 7 installations of controller radiator, and controller radiator 7 and stator support 5 all leave wire hole, for interconnector.After motor and controlling composition one, by ring flange and car load location and installation, output shaft transmitting torque, power and signal transmit by space flight connector.
This embodiment, by the design of integral structure, reduces weight and the volumetric spaces of car load, has increased car load course continuation mileage, by seam and ring flange, conveniently installs with car load.In addition, the appropriate design of electric system electromagnetic circuit, has improved the power density ratio of motor, has increased motor overload ability, meets car load in the operation of various road conditions, reaches energy-efficient object.Meanwhile, the ingenious layout of structure has also facilitated the installation and maintenance of electric system, is applicable in enormous quantities, machineization production.
