Description
Technical field
The utility model belongs to direct current machine field, particularly a kind ofly increases stator tap and can have double dynamical series DC machine.
Background technology
DC motor has the advantages such as controlling electromagnetic torque characteristic good, speed governing is convenient, control technology is ripe, cost is lower.Series excitation DC motor, as the one of DC motor, has its general character, but due to square being directly proportional of the detent torque of series excitation DC motor and armature supply, larger than other types DC motor moment, be widely applied in drilling machinery and electric locomotive.
Series DC machine of the prior art in use, when occurring when overwork, can cause coil windings excess Temperature, is easy to damage motor, extremely wastes user's use cost, and changes motor and return user and caused many troubles.
Utility model content
Technical problem to be solved in the utility model has been to provide and has a kind ofly increased stator tap and can have double dynamical series DC machine, can in the time that overwork motor reaches uniform temperature, change the power of motor, is not easy to cause the damage of motor.
Technical scheme is as follows
A kind of stator tap series DC machine, comprises stator and rotor, and described rotor is arranged in stator, and described stator comprises the pole core being symmetrical set, around left and right excitation winding and patchboard on pole core, in described left excitation winding, there is connecting line a1, a2, has connecting line b1 in right excitation winding, b2, described connecting line a1, b1 parallel connection, connecting line a2, b2 parallel connection, and be connected in the terminals on patchboard, it is characterized in that, in the excitation winding of described left and right, extract respectively left tap and right tap out, connecting line a3 is extracted in described left tap out, a4, connecting line b3 is extracted in described right tap out, b4, described patchboard is provided with A1 terminals, A2 terminals, D1 terminals, D2 terminals and F terminals, connecting line a1, after b1 parallel connection, connect described A1 terminals, connecting line a2, after b2 parallel connection, connect described A2 terminals, connecting line a3, after a4 parallel connection, connect described F terminals, connecting line b3, after b4 parallel connection, connect described terminals F, described terminals D1 is connected a pair of carbon brush with D2, and described carbon brush contacts with described rotor.
As further improvement, between described any one group of excitation winding and pole core, be provided with an attemperating unit, the sensing point of attemperating unit, near excitation winding, is convenient to measure the temperature of excitation winding.
As further improvement, the tap of described left and right is all extracted out from excitation winding center, left and right.
Beneficial effect
The utility model is utilizing tap in excitation winding, and also just having formed left tap and right tap in excitation winding is (fast) powered by conventional energy, and a2, b2 increase umber of turn and increased power (underspeeding).Attemperating unit can be changed the power of motor after connecting transducer in the time that overwork motor reaches uniform temperature, and then increase moment strength (the large motor speed of moment strength is slow) thus reduce electric current, reduce electric machine temperature rise and reduced motor spoilage simultaneously, lacked unnecessary loss for user reduces.
Brief description of the drawings
Further illustrate the utility model below in conjunction with accompanying drawing and case study on implementation.
Fig. 1 is structural representation of the present utility model;
Number in the figure: 100, stator 110, pole core
120, excitation winding 130, patchboard
200, rotor 300, carbon brush
400, attemperating unit
Embodiment
For making that architectural feature of the present utility model and effect of reaching are had a better understanding and awareness, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of stator tap series DC machine, comprises stator 100 and rotor 200, and rotor 200 is arranged in stator 100, and stator 100 comprises the pole core 110 being symmetrical set, around left and right excitation winding 120 and patchboard 130 on pole core, in left excitation winding, there is connecting line a1, a2, has connecting line b1 in right excitation winding, b2, connecting line a1, b1 parallel connection, connecting line a2, b2 parallel connection, and be connected in the terminals on patchboard 130, in the excitation winding of left and right, extracting respectively a winding wire out is that left tap and a winding wire are right tap, left tap forms two connecting line a3 after extracting out, a4, right tap forms two connecting line b3 after extracting out, b4, patchboard 130 is provided with A1 terminals, A2 terminals, D1 terminals, D2 terminals and F terminals, connecting line a1, after b1 parallel connection, connect A1 terminals, connecting line a2, after b2 parallel connection, connect A2 terminals, connecting line a3, after a4 parallel connection, connect F terminals, connecting line b3, after b4 parallel connection, connect terminals F, terminals D1 is connected a pair of carbon brush 300 with D2, and carbon brush 300 contacts with rotor.Because motor can produce heat in the process of running up, the too high motor that will cause of heat damages, therefore the utility model has been done further improvement, between any one group of excitation winding and pole core, be provided with an attemperating unit 400, attemperating unit 400 is for testing the temperature of stator, it connects the transducer of series DC machine outside, while making it reach uniform temperature, exchanges power, reach motor can be because of excess Temperature impaired object.Because left tap and right tap are (fast) powered by conventional energy, connecting line a2 and b2 are that the number of turn that increases excitation winding increases power (lowering speed), and two connecting lines of each formation are preferably extracted in the tap of therefore extracting out out from the center of left and right excitation winding.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the shape described in the utility model claim scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present utility model.
