Description
Technical field
What multi-purpose electric motor of the present invention related to is a kind of multi-purpose motors such as electricity starts, generating igniting, charging that have.
Background technology
Usually, it is motionless that permanent magnet DC motor is generally permanent magnet, and armature rotates.At present, motor vehicle igniter, Blast Furnace Top Gas Recovery Turbine Unit (TRT) such as motorcycle, motor tricycle, minicar are separated, and some motorcycle does not also have electricity to open function.Motor vehicle fly-wheel type permanent magnet ac generator devices such as motorcycle drive flywheel by bent axle and rotate, generate electricity in flywheel, supply with charge in batteries, light a fire to Motronic control maps.Starting drive generally has two kinds, a kind of is to start by recoil to adopt foot-operated the startup, another kind of electricity starts to be supplied with the starter motor electric current by storage battery and drives the reduction gearing mechanism freewheel clutch and help bent axle and rotate ato unit work, and its complex structure, cost height, noise are big.
Summary of the invention
The objective of the invention is provides a kind of multi-purpose electric motor at above-mentioned weak point, and multiple uses such as electricity startup, generating, charging, igniting are integrated in one, mutually independent during work, do not disturb mutually.This design of electrical motor is reasonable, has changed the conventional motors structure, has easy for installation, with low cost, advantages such as volume is little, starting torque is big, toggle speed is fast, charge efficiency is high, noiselessness.
Multi-purpose electric motor takes following scheme to realize: the multi-purpose electric motor structure has motor housing, the motor permanent magnet device is in motor housing, returning apparatus has brush holder in the motor housing, loading amount has carbon brush on the brush holder, stage clip, brush holder, carbon brush, stage clip rotates with motor housing, reverser assembly is on armature core, armature core is fixed on the electric baseboard, as stator, coil winding is on armature core, commutator is housed in the motor housing, commutator has commutator bushing, commutator bushing is equipped with commutator segment, the positive supply copper ring, negative supply copper ring (negative pole) device is in the commutator segment both sides, and carbon brush is divided into two groups, one group by stage clip and commutator segment, the positive supply copper ring contacts, and another is organized by stage clip and commutator segment, the negative supply copper ring contacts.Motor housing can directly adopt flywheel.There are axis hole that power transmission shaft is installed or the crankshaft hole that bent axle is installed in motor housing or flywheel middle part.Here, iron core is made stator, and motor housing or flywheel are made rotor.Coil comprises actuating coil, igniting charge coil, power coil, and three coil windings are on same armature core, and actuating coil, power coil are independently separately.
Multi-purpose electric motor operation principle: when multi-purpose electric motor starts at electricity, battery feed imports commutator segment by positive and negative power supply copper ring and carbon brush respectively, provide electric current to motor, make motor housing (flywheel) rotation, drive engine start work by power transmission shaft (bent axle).The igniting charge coil generation current/voltage that is wound on the armature core offers the CDI ignition coil power supply, ignition igniting, engine operation.Starting power supply after the engine operate as normal withdraws, drive motor housing (flywheel) running by power transmission shaft (bent axle), motor igniting charge coil continues to provide CDI ignition coil power supply to engine, another group power coil provides illuminating lamp, indicator light, motor-operated horn, control instrument operate as normal power supply, and charges to storage battery.As do not have when starting power supply, can ride the engine start bar and drive motor housing (flywheel) and rotate, motor igniting charge coil offers CDI igniter power supply, ignition igniting, engine operation.
Multi-purpose electric motor is because armature coil comprises actuating coil, igniting charge coil, power coil, three winding techniques are on same armature core, armature core is made stator, motor housing or flywheel are made rotor, device has commutator, electricity can be started multiple uses such as generating, charging, igniting and be integrated in one, separate during work, do not disturb mutually.Multi-purpose electric motor is reasonable in design, and little, easy for installation, the electric ato unit moment of torsion of volume is big, toggle speed is fast, safe and reliable, noiselessness, output voltage stabilization, charge efficiency height.Multi-purpose electric motor can be made motor vehicle necessary electromotors such as motorcycle, motor tricycle, minicar, also can make automatic controls motor and other purposes motors.
