Description
Technical field
The utility model relates to technical field of motor accessories, especially a kind of minisize dc formula motor.
Background technology
Direct current machine refers to the electric rotating machine that direct current energy can be converted to mechanical energy or mechanical energy be converted to direct current energy.It to realize the motor that direct current energy and mechanical energy changes mutually.Be DC motor when it makes motor running, convert electrical energy into mechanical energy, be DC generator when making generator operation, mechanical energy is converted to electric energy.Traditional DC motor structure is complicated, and volume is large, complex operation, and operation stability is poor, and output performance is poor, and useful life is short simultaneously, needs often maintenance and renewal part, adds use cost.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, stable minisize dc formula motor.
The utility model solves the technical scheme that its technical problem adopts: a kind of minisize dc formula motor, comprise support, support two ends are provided with end cap, described support center is built-in with rotating shaft, armature core is arranged with outside rotating shaft, armature core external peripheral surface offers groove, and groove is embedded in and is provided with armature winding; Described inboard wall of base is arranged at intervals with main pole and commutating pole, is arranged with excitation winding outside main pole, is arranged with commutation winding outside commutating pole; Be arranged with commutator outside described rotating shaft, commutator is positioned at armature core side, is provided with brush above commutator, and commutator is connected with armature winding; Described support is built-in with the fan for dispelling the heat.
Commutating pole is arranged between two adjacent main poles, is screwed on support, is used for improving the commutation of direct current machine; The effect of brushgear is the sliding contact of the commutator face by brush and rotation, and the armature winding rotated and external circuit are coupled together; For generator, the effect of commutator is that the alternating electromotive force in armature winding is changed into direct electromotive force. externally output dc voltage, and for motor, it is that the alternating current that the direct current of external world's supply changes in winding is rotated to make motor.
Further, described brush is fixedly mounted on inside end cap by brush holder.It is insulation system between brush and brush holder.
Further, described support outer wall is provided with terminal box, and terminal box is by being wired to brush holder.
Further, described end cap is provided with the bearing for supporting revolving shaft.
