Abstract
The utility model discloses a multiple functional motor which can be used as a motor, a generator, or an electric welding machine. The inner part of the existing metal motor casing is provided with a stator winding; the casing is additionally provided with a composite structure of a harmonic winding, a damper winding, an excitation winding, an electric welding winding, and a rotor with salient poles; the out part is provided with a distribution box. When the stator winding is switched with three phase electricity, the motor is operated; when the electric welding machine needs using, the motor load can be disassembled. When the generator is used, the generator is driven by a diesel engine, when the rotary speed reaches 1500 revolutions per minute, the harmonic winding can electrically induct a harmonic electromotive voltage, the electricity generating purpose can be achieved, and the electric welding machine can also be operated.
Description
It is the device of one that the utility model relates to a kind of generator, electric welding machine, motor.
At present, known motor, generator, electric welding machine all use with single function, but when the non-transformer operation, really need the equipment of multiple function.
It is the multifunctional equipment of one that the purpose of this utility model provides a kind of generator, energy-saving electric welding machine, motor, has distribution box to finish the function of using this equipment separately outward.
The utility model is achieved in that when using motor; Three-phase electricity on stator winding is logical relies on the effect of starting damping winding and rotating magnetic field, and motor has just been started working.When using electric welding machine; Three-phase electricity on stator winding is logical, rely on starting group Buddhist nun's winding and rotating magnetic field effect just slowly to turn over, when rotor revolution number during near synchronous revolution 95% through the double end switch motor seat of closing, there are 380 volts of voltages to enter adjustable rectifier transformer, rectifier is started working, pass through adjustable resistance again, add the DC excitation electric current for the rotor-exciting winding, power factor be transferred to 1 more before, at this moment rotating magnetic field will be rotor pull-in step revolution, the electric welding winding produces induced electromotive force, through the reactor current limliting, and electric welding machine can work (unloading induction-motor load when using electric welding machine).When using generator; Be used as power with 15 horsepower diesels, the rotation of drive generator, when revolution reaches specified (1500 rev/mins), field spider remanent magnetism will induce the harmonic wave electromotive force in humorous wave winding, start working through the switch generator seat rectifier that closes, through adjustable resistance, add the DC excitation electric current for the field spider excitation winding, at this moment three-phase stator winding and electric welding machine winding have produced induced electromotive force, have just sent electricity, also can be used as electric welding machine and use, so just played the effect of a tractor serves several purposes.
Owing to adopt such scheme, can in environment separately, play the function of generating, electric welding, motor.
Below in conjunction with drawings and Examples the utility model is further specified.
Figure of description is the utility model circuit theory diagrams.
Among the figure: 1, stator winding 2, body fuselage 3, the humorous wave winding 4 of field spider, damping winding 5, adjustable resistance 6, double end switch 7, adjustable rectifier transformer 8, excitation winding 9, electric welding winding 10, reactor 11, rectifier 12, electric welding 13, distribution box
In the accompanying drawings, when motor is worked; In the logical three-phase electricity that goes up of stator winding (1), rely on the effect of starting damping winding (4) and rotating magnetic field, motor has just been started working.When using electric welding machine; Deciding the logical three-phase electricity that goes up of winding (1), rely on starting damping winding (4) and rotating magnetic field effect, rotor has just started, when rotor revolution number during near synchronous revolution 95%, through double end switch (6) the motor seat of closing, there are 380 volts of voltages to enter adjustable rectifier transformer (7), rectifier is started working, through adjustable resistance (5), add the DC excitation electric current for rotor-exciting winding (8), power factor be transferred to 1 more before, at this moment rotating magnetic field will be rotor pull-in step revolution, electric welding machine winding (9) produces induced electromotive force, through reactor (10) current limliting, and electric welding (12) can work (unloading induction-motor load when using electric welding machine).When using generator; Be used as power with 15 horsepower diesels, the rotation of drive generator, be 1500 rev/mins when reaching rated revolution, field spider remanent magnetism will (3) induce the harmonic wave electromotive force in humorous wave winding, through double end switch (6) the generator seat of closing, rectifier is started working, add the DC excitation electric current for field spider (8) excitation winding through adjustable resistance (5), at this moment three-phase stator winding (1) and electric welding winding (9) produce induced electromotive force, have just sent electricity, also can use as electric welding machine separately.So just played the function of a tractor serves several purposes.
