Description
Technical field
the utility model relates to technical field of motors, specifically a kind of four pole direct current permanent magnet motors be applied on automobile power back door strut.
Background technology
Four current pole direct current permanent magnet motors are applied on electric tail gate strut, the four pole magnet rings adopted are without location structure, N, a small gap is had as the mark of geometric center lines between S magnetic pole, also be magnetic pole line of demarcation, blocking small gap by fixture is installed in metal shell, such magnet ring easy deviation angle or anti-loaded, also be the easy deviation angle of geometrical neutral line and carbon brush position or reverse, because the motor on electric tail gate strut all requires rotating, carbon brush is just needed to be placed in the geometric center lines of motor, if carbon brush departs from geometric center lines, the main field that the armature field that the rotor windings then contacted with it produces will make stator magnetic ring produce distorts, by generation two kinds of armature reactions: i.e. d-axis armature reaction and quadrature axis armature reaction, thus distorted in resultant magnetic field in space, affect motor normally to work, lower efficiency, change motor performance.Due to armature reaction, reverse and machine operation magnetic flux can be made to reduce to deviation angle, cause motor speed to raise, have demagnetizing effect.Clockwisely machine operation magnetic flux can be made to increase to deviation angle, cause motor speed to reduce, help magnetic action.If deviation angle is excessive, can produce abnormal commutation spark, also there is different changes in current of electric, and electrical machinery life is shortened, and produces electromagnetic interference etc., can burn out commutator and brush, even motor damage time serious.
Just because of the angle of carbon brush position and geometric center lines is so important, the angle accuracy just needing to avoid motor magnet ring to install and 180 degree of anti-loaded possibilities, cause occurring that motor steering is anti-, commutation spark is large and the life-span is short, produce electromagnetic interference, rotating speed height, size of current is inconsistent to be waited extremely.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of four pole direct current permanent magnet motors, installs simple, easy to operate, there will not be and fill inclined or anti-loaded hidden danger, have structure simple, simple to operation, has good error-disable function.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of four pole direct current permanent magnet motors, comprise end cap, stators and rotators, rotor is contained in stator, and end cap is contained in stator one end, and described stator comprises shell and is fixed on four pole magnet rings of this outer casing inner wall; The rotor core that rotor comprises cased rotating shaft and is fixed in this rotating shaft, rotor core is wound with winding, rotor core is fixed with commutator, and winding is connected with commutator and conducts electricity, and rotating shaft is set with bearing; End cap comprises cover plate and is contained in the carbon brush arm group on this cover plate, and this carbon brush arm group is equiped with carbon brush, and this carbon brush and commutator sliding contact are conducted electricity; Four pole magnet rings are provided with groove, and outer casing inner wall is provided with boss, and boss when in the enclosure wall being installed four pole magnet rings on shell snaps fits in the groove of four pole magnet rings.
The groove that described four pole magnet rings are arranged at least one, the quantity of the boss on shell and the quantity of groove are consistent.
Described shell is metal shell.
Described cover plate is Jiao Gai.
Described rotor core surface-coated has insulating barrier.
Described carbon brush arm group comprises two carbon brush arms.
Described rotating shaft is also set with axle sleeve.
The utility model by arranging groove on four pole magnet rings, and arranges boss on metal shell, can be arranged in metal shell by four pole magnet rings easily, and there will not be and fill inclined or anti-loaded hidden danger, there is structure simple, simple to operation, there is good error-disable function, ensure that motor steering, commutation spark, life-span, electromagnetic interference, rotating speed, the consistency such as electric current are high.
