Abstract
The utility model discloses an integral brushless motor comprising a controller circuit board, a rear end cap and a stator with notches, the controller circuit board is fixed in a space between the stator and the rear end cap through a connecting device, the controller circuit board is also provided with a plurality of heat radiation sheets, and heat radiation surfaces of the heat radiation sheets are connected with an inner wall of the rear end cap. The integral brushless motor employs a mode in which the heat radiation sheets arranged on the controller circuit board are attached with the motor rear end cap, the heat on the controller circuit board is transmitted to a motor metal housing with a large area for heat radiation, sealing property of the whole motor is ensured, and heat radiation problem of members on the controller circuit board is solved. The integral brushless motor is simple in structure, easy in installation, high in efficiency, long in service life and safe in usage, and the brushless motor can be used in house electric equipment and industrial products with different requirements.
Description
Technical field
The utility model relates to brshless DC motor and makes the field, relates in particular to a kind of integral type brushless electric machine that can be applicable to aspirate in the household electrical appliance such as lampblack absorber, refrigerator, air-conditioning, washing machine.
Background technology
Brshless DC motor is because it has speed-regulating range width, and low-speed performance is good, operates steadily, and noise is low, and the efficient advantages of higher has very widely application in industry and civil area.Yet, in the prior art, brshless DC motor realizes that the controller of start-stop control, forward and reverse control, rotational speed regulation control etc. all is the individual components with respect to the motor main body, controller is arranged on outside motor usually, between the lead-out wire of coil windings and the wiring board adopt to be welded and fixed be connected.This connected mode not only globality is poor, the wiring trouble, and need to reserve specially installing space, it is very inconvenient to use, particularly in fields such as some household electrical appliance, industrial sites, affect extremely easily associative perception and the stability of electrical equipment, and long-time the use also easily because connectivity problem causes device damage.In order to address the above problem, proposed among the Chinese patent ZL201220125359.8 a kind of controller to be installed in brushless electric machine in the motor body, the infringement that is subject at work for reducing controller can be carried out whole embedding to controller in use.Yet, after the embedding on the controller heat radiation situation of each electronic component can be had a strong impact on again, and because one of them electronic devices and components damages, whole controller is scrapped, can not safeguard and repair, be unfavorable for the use of complete machine.
The utility model content
The integral type brushless electric machine that provides a kind of heat that can guarantee that sealing can guarantee that again each electronic component distributes on the controller to be released is provided the purpose of this utility model.
This integral type brushless electric machine that the utility model provides, comprise controller circuit board, rear end cap and with the stator of notch, described controller circuit board is fixed in the space between stator and the rear end cap by jockey, some fin also are installed on described controller circuit board, and the radiating surface of this fin links to each other with the inwall of rear end cap.
Be connected with controller circuit board for avoiding that the three-phase stator winding phase line was intersected line, reduce the situation of phase fault, can directly be welded on the controller circuit board when making things convenient for the stator winding phase line of motor body to draw from notch, also be provided with the some wiring holes corresponding with notch on the stator on the described controller circuit board.
For safe and reliable and do not damage in the situation of stator and controller circuit board, each element of disassembling, assembling and replacing, described controller circuit board adopt screw and the nut of plastics to be mounted on the stator.
The utility model is by installing the pattern that fin and back end cover for motor amplexiform at controller circuit board, heat on the controller circuit board is delivered on the large-area motor metal chassis dispels the heat, both guarantee the sealing of complete machine, solved again the heat dissipation problem of each element on the controller circuit board.The utility model is simple in structure, installs simple and easyly, and efficient is high, and the life-span is long, uses safety, can be adapted in the products such as the household appliances of different requirements, industrial class.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 K-K place partial structurtes schematic diagram.
Fig. 3 is assembly structure schematic diagram of the present utility model.
Embodiment
Can find out from Fig. 1 to Fig. 3, this integral type brushless electric machine that the utility model provides, comprise controller circuit board 1, rear end cap 2, with stator 3 and some fin 4 of notch, controller circuit board 1 is mounted on the stator 3 of rear end cap 2 one sides by screw and the nut of plastics, be provided with the some wiring holes corresponding with notch on the stator 3 at this controller circuit board 1, comprise that fin 4 is installed on the controller circuit board 1 and its radiating surface links to each other with the inwall of rear end cap 2.
It can also be seen that from Fig. 1 wiring hole comprises A, B and C three phase winding head end wiring holes in the utility model, A', B' and C' three phase winding common port wiring holes.
The utility model in use, the winding phase line of stator 3 is drawn rear directly being welded on the wiring hole corresponding with notch position from notch, when outer bound pair power line energising, controller circuit board 1 will directly carry out the electric power conversion, and its signal will be input on the winding of stator 3.
