Abstract
The utility model discloses a novel direct-current power generator which is provided with a stator and a rotor, wherein the stator consists of a first stator winding and a second stator winding that are arranged in parallel; the first stator winding adopts the exciting winding structure of a direct-current motor; the second stator winding adopts the structure of a rotor winding of a direct-current motor without a brush handle of a carbon brush commutator; and the rotor consists of a first rotor winding and a second rotor winding that are arranged in parallel, respectively adopt the rotor winding structure of an alternating-current motor and are connected in series with each other. Compared with the prior art, the novel direct-current power generator is not provided with the commutator and the electric brush device in the existing direct-current power generator, is characterized by being simple in structure, rapid to start, high in efficiency, balanced in running process, hard to be abraded and long in service life, meets the energy-saving policy, has wide application prospect, and can be used for replacing the automobile alternating-current power generator directly.
Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of Novel DC generator.
Background technology
The DC generator major function is to realize the conversion of direct current energy and mechanical energy, the mechanical energy of input DC generator, with the magnetic field in the motor is that intermediary realizes energy converting between mechanical, at last could obtain direct current energy, corresponding structure has complex structure, efficient is on the low side, need unfavorable factors such as frequent maintenance, therefore substituted by the solid rectifying device gradually, the DC power supply of low capacity is often replaced by various storage battery again, so the importance of DC generator and range of application are restricted.The structure of existing DC generator mainly is made of main pole, magnet exciting coil, armature, commutator, brushgear etc., wherein be arranged in cylindrical shape in the V-shaped groove of commutator employing commutator segment embedding metal sleeve, use mica insulation between sheet and between sheet and sleeve, or make commutator segment be fixed as commutator with the plastic hot compression technology.Brush is generally made with carbon-graphite, and brush is inserted in the brush carrier, and brush connects the binding post of motor by the multiply flexible wire, and brush has excellent contact with the commutator requirement, can exist like this both press tension and cause wearing and tearing.So existing direct current machine exists the commutating structure complexity, the problem that brush is easy to wear.
The utility model content
Be to solve the above-mentioned defective that prior art exists, the purpose of this utility model be to provide a kind of simple in structure, starting rapidly, efficient is high, the operation balance, not easy to wear, the Novel DC generator of long service life.
For achieving the above object, the technical solution adopted in the utility model is: this Novel DC generator, have stator and rotor, it is characterized in that: described stator is made of first stator winding that is arranged side by side and second stator winding, described first stator winding adopts the excitation winding structure of direct current machine, second stator winding adopts the structure of rotor DC machine winding, described rotor has two the first rotor windings that are arranged side by side and the second rotor winding constitutes, described the first rotor winding, the second rotor winding adopts the rotor winding structure of alternating current machine, the first rotor winding, the second rotor winding is connected mutually.
Adopt the beneficial effect of technique scheme: the stator of this Novel DC generator is made of first stator winding that is arranged side by side and second stator winding, described first stator winding adopts the excitation winding structure of direct current machine, the first rotor winding adopts the rotor winding structure of alternating current machine, in the excitation winding of generator, form the AC magnetic field of constant direction, on the first rotor winding, induce AC electromotive force, because the second rotor winding is connected mutually with the first rotor winding, so the second rotor winding also has the alternating current impression electromotive force, under the rotation of the second rotor winding drives, produce the magnetic field of constant direction, because second stator winding adopts the structure of the rotor DC machine winding behind the removal carbon brush commutator brush carrier, so induce direct voltage on second stator winding.Compared with prior art, this Novel DC generator has saved commutator, the brushgear in the existing DC generator, has simple in structurely, starts rapidly, the efficient height, the operation balance, not easy to wear, the long service life characteristics meet energy saving policy, will have wide practical use.
Description of drawings
Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is second stator, rotor winding position electromagnetic induction schematic diagram.
