Embodiment
Embodiment 1:
As shown in Figure 1, coaxial reactivation drives bending moment DC motor, comprises support, support is provided with housing 11, housing 11 is provided with end cap 3, installs two DC motor: the first DC motor, the second DC motor on housing 11.First DC motor comprises the first armature portion 6, first stationary part, and the first armature portion 6 is provided with the first commutator 4, first stationary part and is provided with the first change field pole 5, first brushgear 3.Second DC motor comprises the second armature portion 8, second stationary part, and the second armature portion 8 is provided with the second commutator 9, second stationary part and is provided with the second change field pole 7, second brushgear 10.The rotating shaft of the first armature portion 6 and the rotating shaft of the second armature portion 8 are on same output shaft 1.The armature winding of the first armature portion 6, second armature portion 8 is adopted to power respectively, by respectively to the control in the foundation of the first DC motor, the second DC motor excitation field separately, size and direction, realize the moment of torsion of the corresponding direction of rotation of each DC motor, by same output shaft 1, moment of torsion is merged compound and export.
The moment of torsion way of output 1: after accessing DC power supply to respectively the first armature portion 6, first change field pole 5 or the second armature portion 8, second change field pole 7, two coaxial motors all can independently drive, by output shaft 1 output torque, its output torque is the moment of torsion of single electric motor.
The moment of torsion way of output 2: after accessing DC power supply to the first armature portion 6, first change field pole 5 or the second armature portion 8, second change field pole 7, voltage control is carried out to input power, motor is pure series excitation operating state (adjustment voltage can change motor speed), because series excitation DC motor rotating speed is relevant with load, therefore two coaxial series excitation DC motors are synchronized running all the time.And moment of torsion merged compound by same output shaft 1 and export and drive, its output torque is two coaxial motor output torque sums.
The moment of torsion way of output 3: when motor is subject to outer force reaction, as: when having potential energy reaction, the first change field pole 5 or the second change field pole 7 disconnect series excitation magnetic pole and access his field pole simultaneously.DC motor is operated in pure DC motor with separate excitation state.The utility model DC motor becomes separate excitation DC generator, and when his field pole becoming field pole 5 or the second change field pole 7 to first carries out the control of exciting current size respectively, two motor towing astern rotating speeds and output electric energy can be adjusted respectively.
Embodiment 2:
Coaxial reactivation drives bending moment DC motor, and comprise multiple DC motor, each DC motor comprises armature portion and stationary part, and described multiple direct-current motor armature part installs same output shaft 1.The rotating shaft of multiple direct-current motor armature part is connected on same output shaft 1 by shaft coupling.
The moment of torsion way of output of multiple DC motor is with reference to the mode in embodiment 1.
When two or more DC motor is driven by different electric power source, the technical parameters such as the electric pressure of its different electric power source can be identical, also can be different.Namely two motors can adopt same levels power supply as being designed to same electric pressure. and two motors also can be designed to different electric pressure, and namely high-tension electric motor can by mains-supplied, and low-voltage motor can by battery pack or other Power supply.
The watt level of two or more DC motor can be identical, also can be different.Namely, after the gross power of motor is determined, two motor proportionings can be that 1:1 may also be other proportionate relationships such as 2:1.Scale is determined by the plant machinery characteristic driven.As: 100KW motor can be made up of the motor of two 50+50KW or 75+25KW.
When two or more DC motor has a potential energy reaction, motor converts separately excited dynamo to by series-wound motor, can realize generator function respectively, exports electric energy.
