Abstract
The utility model discloses an integral brushless motor. The integral brushless motor is characterized by comprising a housing, and a front coil bracket, a stator core, a rear coil bracket, a rotor magnet and a printed circuit board (PCB), which are arranged on the same rotating shaft in the housing, wherein a rotor core is arranged in the rotor magnet; and the stator core is arranged between the front and rear coil brackets. The integral brushless motor is simple in structure, convenient to mount, environment-friendly and energy-saving, and has high popularization value.
Description
Technical field
The utility model relates to technical field of motors, relates to a kind of brushless electric machine in particular.
Background technology
Brshless DC motor is made up of motor body and driver, is a kind of typical electromechanical integrated product.Because brushless DC motor is with autocontrol operation, on rotor, do not add the startup winding so can not resemble in addition the synchronous machine of heavy load starting under the frequency control, can when load changing, not produce yet and vibrate and step-out.Like one Chinese patent application number is CN201010190780.2, and denomination of invention is for comprising: stator, and it comprises stator core and winding, and said stator core has some utmost points that inwardly stretch out, and said winding is wound into the said utmost point; And rotor, the magnet that said rotor comprises rotating shaft, is fixed to the rotor core of rotating shaft and is fixed to said rotor core, said magnet is at the some magnetic poles of circumferential formation of said rotor core; Said rotor is pivotally mounted to said stator through said rotating shaft, and the salient pole of said stator has the pole shoe that stretches along periphery of rotor, and the polar arc face of said pole shoe and said rotor core separate relatively and by an air gap; On the radial section of said motor, the effective width of the magnet of each magnetic pole (W) equals 0.85 to 1.2 times of chord length (L) of said polar arc face.The brushless electric machine of this patent can reduce leakage field, improve motor properties, but manufacturing cost is higher, and power consumption is big.
Summary of the invention
The purpose of the utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, low cost of manufacture, and the integral type brushless electric machine of environmental protection and energy saving.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of integral type brushless electric machine; It is characterized in that; It comprises shell and in be arranged on coil fore-stock, stator core, coil after-poppet, rotor magnet and the pcb board in the same rotating shaft; Be provided with rotor core in the rotor magnet, stator core is arranged between coil fore-stock and the coil after-poppet.
As further specifying of such scheme: said shell is a plastic casing, comprises that fore shell and band wave the support back cover.
The contact-making surface outer rim of said fore shell and back cover stretches out and is flange, and flange is provided with the screw more than three, has securing member that fore shell and back cover are fixed as one on the screw.
The two ends of said rotating shaft are respectively arranged with bearing, and this bearings at both ends is individually fixed in fore shell and the back cover.
Said stator core ringwise, its set inside has several utmost points that extends internally, and is wound with coil on extremely.
Said pcb board is ring-like, is fixed in the bottom of back cover.
The bottom of said fore shell is bolted with vertical shaft.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts incorporate brushless motor structure, and the shell of motor made of plastic, reduces production costs significantly, and it can be applied on the electric fan, and can design the size of stator coil, environmental protection and energy saving according to the requirement of different capacity.
