Abstract
A double-rotor differential speed DC motor comprises a stator installed in metal shell and two rotors. One end of two rotors of the same parameters can form concentric connection in the rotary way, and another two ends are taken as the transmission shaft after drilling through the bearing and extending outside the shell. Two rotor coils are in serial connection with each other through brush. When their moments are the same, the rotation speeds of the motors are the same as well. When the moment at one end is increased, the speed will decline. The voltage at the two ends of the rotor will decline because of the reduction of inductance. Since the two rotors are in serial connection, the voltage at the two ends of another rotor will rise quickly. With stable performance and low energy consumption, the utility model can be used to drive electric vehicles and robots directly.
Description
Affiliated field
The utility model relates to a kind of power set that are used for Drive for EV, especially adopts the birotor both-end to export in the same way or oppositely, and regulates the DC motor that power distribution realizes differential according to actual needs automatically.
Background technology
At present, known for electric automobile provides the DC motor of power all to need additional differential gear and can only export in the same way, any device all can increase the weight of energy consumption and production cost and car load.
Summary of the invention
Do the deficiency of driving device for electric vehicle in order to overcome existing direct current machine, the utility model provides a kind of direct current machine, and this direct current machine can realize that without any need for attachment device automatic adjusting differential, the constant speed of two concentric driving shafts reach in the same way or oppositely output.
The technical scheme that the utility model technical solution problem is adopted is, in the metal object.The end that two identical rotors of parameter do not have commutator segment is made rotatable concentric connection back public same armature (being stator), and two ends are passed bearing respectively and done power transmission shaft in addition, and two rotor coils are connected by brush.Rotating speed of motor is identical when moment is identical, rotating speed can descend when an end moment strengthens, the voltage of two ends of rotor can reduce to descend because of its induction reactance, because of so two rotors are another two ends of rotor voltage of series connection faster rotational speed that can rise, so can not rise De Taigao because the D.C. resistance of coil can not reduce the voltage difference of two rotors.Change two rotor coils connections and can realize reverse output.Reach automatic adjusting differential, constant speed and export purpose in the same way or oppositely.
The beneficial effects of the utility model are, can realize the output of differential moment in power conversion, also have twin shaft and export changeable in the same way or oppositely.Directly can be used for fields such as electric automobile, robot; Energy savings, promotion prospect is extensive.
