Abstract
The utility model relates to a multi-function motor which relates to a dynamic force motor and a direct current-alternating current high voltage-low voltage changing device. A direct current coil and an alternating current coil are arranged on a rotor of the motor simultaneously. Simultaneously, a commutator segment and a sliding ring are arranged on the motor. Each coil is composed of a plurality of windings. Leading wires on the ends of the windings are led out. The coil and the sliding ring are connected through a converting switch by various selecting modes. The commutator segment makes the motor become a generator, an electric motor, a direct current motor, an alternating current motor, a direct current converter and an alternating current converter. The multi-function motor can be used for different voltages and has various functions.
Description
A kind of multi-function motor relates to power motor and direct current and exchanges, the equipment of conversion between high pressure and the low pressure.
Prior motor, function all are single, and direct current machine can only be used for direct current.Alternating current machine can only be used for exchanging, and generator can only be used for generating electricity, and motor can only be worked as motor and be used.Produce and life in have to purchase the motor of many various simple functions when needing these functions, equipment investment is bigger, it is many to take up room, and since non-while of Ren And and use various functions incessantly cause the idleness of equipment time long.
Task of the present utility model provides a kind of motor with following various basic functions: the function of (one) AC and DC generator, promptly under the impressed torque situation, can send alternating current and direct current at the same time or separately; (2) DC motor function promptly makes its rotation with dc powered; (3) the alternating current generator function of DC driven, i.e. direct current, AC converter; (4) alternating current motor function, promptly alternating current drives and makes its rotation.
The same with general motor all have stator 16 and a rotor 17, different is that the utility model is equipped with two cover coils on same rotor, use for AC and DC respectively, and on same rotor, be provided with slip ring 15 and commutator segment 14, each winding of coil and commutator segment, all leaded contact of receiving change over switch 18 of slip ring, change each contact with change over switch and connect situation, just can control between the winding and between winding and slip ring or the connecting mode between winding and commutator segment, different connecting modes makes motor have different functions.
As can be seen, the utility model rotor coil has two covers from accompanying drawing, i.e. the dc coil of the AC coil of 3-10,4-9 formation and 5-8,6-7 formation.Every cover coil can be made of simplex winding or two above windings.Two cover coils are contained on the same rotor, are in the magnetic field of same stator, and two cover coils can be made of its winding parallel connection or series connection.When dc coil two termination commutator segments, during AC coil two termination slip rings, the utility model has just become a double current generator, if to rotor with torque, dc terminal just produces direct electromotive force., exchange to hold and just to produce AC electromotive force.This connecting mode can also be used as DC motor and direct-current-alternating-current converter, as long as apply direct voltage in dc terminal, then rotor rotates immediately.Simultaneously produce alternating voltage exchanging end, can connect external circuit and use, also can not connect external circuit, do not use alternating current and a rotor that rotates is used as motor.
If load onto a rectification circuit in dc terminal of the present utility model, just DC motor function of the present utility model has been become the alternating current motor function, can regard alternating current machine, boost or step-down transformer usefulness.
The function of the original motor of function ratio of the present utility model is many, and it can also can be used as a DC generator as a DC generator and/or an alternating current generator usefulness.Behind rectifier of direct current termination, can also use as alternating current motor or transformer.Realize a tractor serves several purposes, reduce equipment investment, improve capacity utilization.
