Abstract
The utility model relates to a coreless motor. The coreless motor comprises a casing (1), a central magnet (2), commutators (3,4) arranged at an outer bearing diameter and a rotor (5), wherein a back end of the rotor (5) is fixed on a first bearing (9). The coreless motor is characterized in that a front end of the rotor (5) is connected with a shaft (6), and the shaft (6) penetrates through a second bearing (10) fixed on the casing (1). The coreless motor realizes double-bearing support of a coil, solves problems of low stability and low reliability caused by single-bearing support in a coil in the prior, improves reliability and stability of a structure, moreover, the coreless motor employs dual magnets and makes the motor generate a stronger magnetic field and have a greater torque.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of drag cup direct current machine.
Background technology
More use drag cup motor in the present electronic product, the drag cup motor typically refers to a kind of structure of brush direct current motor.The drag cup motor has housing, is provided with brush at an end of housing, is provided with motor stator and the rotor be made up of axle, commutator assembly, drag cup coil, magnet steel, bearing etc. in housing.Existing drag cup motor profile is cylinder or cylindrical shape, and brush direct current motor is by magnets of stator, rotor line bag, and commutator, brush, axle, bearing, end cap, parts such as shell are formed, as figure one.
Traditional rotor line bag is around to tin steel lamination.So-called drag cup motor, shown in figure two, the only wired bag of its rotor does not have tin steel lamination.Magnet is positioned at the center, and is fixed on the shell.The front end of line bag is unsettled.There is bearings the rear end of line bag, and so-called " rear end " has been meant phase changer, that end of brush, and so-called " front end " is meant there is not phase changer, that end of brush that is to say that the line bag is single bearings.The line bag stability of this structure, reliability is difficult to reach requirement.
Summary of the invention
The utility model has designed a kind of drag cup motor of new construction, with the line bag that solves prior art hollow core cup motor is that the front end of rotor is unsettled, there is bearings the rear end of line bag, that is to say that the line bag is single bearings, the line bag stability of this structure, reliability is difficult to the problem of meeting the requirements of, and the purpose of this utility model is to provide a kind of novel hollow cup motor, is used to improve the stability and the reliability of drag cup motor.
The technical scheme that the utility model adopted is a kind of drag cup motor, comprise shell 1, centring magnet 2, be positioned at the commutator 3 at bearing outside diameter place, 4, rotor 5, rotor 5 rear ends are fixed on the bearing one, the front end that it is characterized in that rotor 5 is connected with axle 6, and axle 6 passes the bearing two that is fixed on the shell 1.So-called " rear end " has been meant phase changer, that end of brush, and so-called " front end " is meant there is not phase changer, that end of brush.
Described bearing one is outer transition, and promptly shell rotates;
Described bearing two can with gear box or miscellaneous part, such as load, shared bearing;
Described internal diameter of outer cover place is provided with magnet 7,8, and rotor is positioned between centring magnet 2 and the magnet 7,8, producible magnetic field, and moment of torsion is bigger;
Adopt the drag cup electric machine structure of the utility model design, realized that the duplex bearing of line bag supports, overcome in the prior art coil single shaft and held and support the stability of bringing, the defective that reliability is not high has improved the reliability and stability of structure.Further, the utility model adopts dual magnet, and the magnetic field that motor is produced is stronger, and moment of torsion is bigger.
