Description
Technical field
The utility model relates to a kind of pair of combinatorial DC electrical motor.
Background technology
Direct current machine is to be the motor of power supply with the direct current.Because direct current machine has advantages such as detent torque is big, operating noise is little, control is convenient, on various mobile devices, use as power set, use very general.On at present popular gradually electric automobile, direct current machine more is absolutely necessary and mainly disposes.At present, the employed motor of known electric automobile generally comprises housing, is rotatablely equipped with rotor on the housing, and the rotor winding is installed on the rotor, is provided with the stator winding corresponding with the rotor winding in the housing.The weak point of tradition direct current machine is; One, owing to receives power output to increase the influence that requires; General stator winding is provided with thicklyer; Therefore radially volume is bigger for direct current machine, certainly will cause rotor winding making materials like this and make the increase in man-hour, has also just caused the significantly lifting of cost.With regard to the DC motor more than three kilowatts, its production cost and selling price are generally all more than several thousand yuan.And supporting with it DC motor control system, owing to be controlled the influence of power, production cost also is high.For powerful electric automobile, must more powerful direct current machine of configuration and control system.Use traditional direct current machine and control system thereof, not only can cause cost to raise, and occupation space is also bigger on automobile.Two, under the control of control system; No matter power output is much; Whole rotor winding is in the energising operating state always, and the acting of rotor winding, heating are also being carried out always, therefore is unfavorable for the job stability and the useful life of rotor winding and even whole direct current machine.
The utility model content
The technical problem that the utility model will solve is to provide a kind of rational in infrastructure to above-mentioned deficiency, and volume is moderate, make save time, cost is low, and helps two combinatorial DC electrical motors of increasing the service life.
For solving the problems of the technologies described above; This pair of combinatorial DC electrical motor comprises housing; Be rotatablely equipped with rotating shaft on the housing; Its design feature is: main rotor winding and secondary rotor winding are installed in the rotating shaft vertically at least; The rotating shaft both ends are equipped with main converter that is connected with the main rotor winding electric and the secondary rectifier that is connected with secondary rotor winding electric respectively, and housing is provided with the main carbon brush mechanism that cooperates with main converter and secondary rectifier respectively and secondary carbon brush mechanism, is provided with the main stator and the secondary stator that cooperate with main rotor winding and secondary rotor winding respectively in the housing.

As improvement; Also comprise the controller that is electrically connected with main carbon brush mechanism and secondary carbon brush mechanism; The input of controller is electrically connected with the signal converter that the actuating signal of pedal or handgrip is converted into the control signal of telecommunication, and the signal converter is worked or time-sharing work through controller control main rotor winding and secondary rotor winding simultaneously.
Be electrically connected controller in main carbon brush mechanism and secondary carbon brush mechanism input, can control automatically, help to ensure control precision and functional reliability the power supply and the concrete operating state of main carbon brush mechanism and secondary carbon brush mechanism.The controller input connects the main effect of signal converter, is the operating pedal or the actuating signal of rotating the handgrip input are converted into analog electrical signal or the digital electric signal that controller can receive.Like this, people just can make controller to main combination and secondary array output different voltages with different or electric current through press degree of pushing pedal or the degree of rotation of rotating handgrip, thereby reach the control of different output power, and are very convenient.
As further improvement, controller comprises the main controller that is electrically connected with main carbon brush mechanism and the joystick controller that is electrically connected with secondary carbon brush mechanism, and the input of main controller and joystick controller is electrically connected with same signal converter or is electrically connected with a signal converter respectively.
Connect main controller and connect joystick controller at main carbon brush mechanism input at secondary carbon brush mechanism input; Can control separately main combination and secondary combination respectively through main controller and joystick controller; Like this; Not only help to improve control reliability, and can also reduce the function of control system, also just played the effect that reduces cost.Be electrically connected same signal converter at main controller and joystick controller input, can realize unified control main combination and secondary combination.Be electrically connected a signal converter respectively at main controller and joystick controller input, not only realized the independence of main combination and secondary combination, and control system be also independent, helps to realize the output of this pair combinatorial DC electrical motor different capacity from mechanical structure.
In sum, adopt two combinatorial DC electrical motors of this structure, rational in infrastructure, volume is moderate, and manufacturing saves time, cost is low, and helps to increase the service life, and is particularly suitable on electric automobile, using.
