Abstract

The utility model discloses a D. C. dual-purpose dynamo which combines functions of an electric motor and an induction generator, aiming to provide a D. C. dual-purpose dynamo which can not only generate the mechanical energy but also can generate the electrical energy, and namely, combining the electric motor and the induction generator. The D. C. dual-purpose dynamo is characterized in that the rotor of ordinary the DC motor is provided with a DC generator coil winding, and the other end of the shaft of the DC motor is provided with a DC generator metal slip ring, a carbon brush of DC electric generator, a spring, a lead wire for DC generator. The utility model can generate the electrical energy simultaneously when the storage battery provide power to generate the mechanical energy, the electrical energy generated is recharged into the storage battery via diodes, which can extend the power-on time of the storage battery and save energy. The utility model can be used as the electric motor and the electric generator simultaneously.

Description

Dc two-purpose motor

Technical field

The utility model relates to the hold concurrently dc two-purpose motor of induction generator of a kind of motor.

Background technology

Common DC motor mainly is made of two groups of stators, a rotor.Every group of stator is around one group of coil on silicon steel plate.Perhaps directly use two block permanent magnets.Also have two carbon brush.Be wound with many group coils on the rotor, every group of coil is connected on the corresponding metal slip ring in order.Common DC motor can only produce single mechanical energy, can not make generator simultaneously and use.

Summary of the invention

The purpose of this utility model provides a kind of dc two-purpose motor, can produce mechanical energy, and can produce electric energy again, i.e. motor and induction generator dual-purpose.The utility model is realized with following mode: a kind of dc two-purpose motor, and it has motor housing 1, and its inwall has stator 3 and

stator winding

2, or 2 block permanent magnets, and stator winding 2 connects spring 5, direct current machine carbon brush 4 by connecting line 6; Axle 15 is arranged on motor housing 1 inside center line and rotor 10 is housed, direct current machine coil windings 8 is arranged on rotor 10, one end of axle 15 is equipped with direct current machine metal slip ring 7 and connects direct current machine coil windings 8, it is characterized in that on rotor 10, also having DC generator coil windings 9, and the end in addition at axle 15 also has DC generator metal slip ring 11 and connects DC generator coil windings 9, also has generator carbon brush 12, spring 13, DC generator lead-out wire 14 at DC generator metal slip ring 11 ends; Above-mentioned direct current machine coil windings 8 inserts the positive pole of storage battery E by K switch; Above-mentioned DC generator coil windings 9 inserts the positive pole of storage battery E by diode D; Negative pole and above direct current machine coil windings 8, direct current machine coil windings 9 that lead 16 inserts storage battery E are formed the loop respectively.The utility model also produces electric energy when storage battery power supply produces mechanical energy, the electric energy that is produced recharges in the storage battery through diode, prolongs the power-on time of storage battery; Energy-conservation.The utility model makes motor and generator is dual-purpose.

Description of drawings

Fig. 1 is the utility model and storage battery E connecting circuit figure.

Fig. 2-Fig. 3 is a structural representation of the present utility model, and wherein Fig. 3 is that the A of Fig. 2 is to view.

Embodiment

Now the utility model is described in further detail in conjunction with the accompanying drawings.With reference to Fig. 1-Fig. 3, the utility model is that the other end 10 15 of the rotors of common DC motor increases by one group of DC generator metal slip ring 11, increase DC generator coil windings 9 in order again on every group of direct current machine coil windings 8 on original rotor 10, the end line of every group of coil is serially connected on the DC generator metal slip ring 11 that increases newly in order, and increases dress generator carbon brush 12.The utility model is made DC motor, generator dual-purpose.DC motor is when storage battery E power supply running produces mechanical energy, and the DC generator coil windings 9 on the rotor 10 produces induced current, and this electric current recharges in the storage battery E through diode D, thereby prolongs storage battery E power-on time.Specify and be: storage battery E from positive pole through K switch to direct current machine carbon brush 4 to direct current machine metal slip ring 7 again to direct current machine coil windings 8, get back to storage battery E negative pole, motor rotor 10 running.At this moment DC generator coil windings 9 produces induced electricity, to generator carbon brush 12, flows back to storage battery E through diode D through DC generator metal slip ring 11 again.
