Abstract
The utility model discloses a brushless starting magneto for a motorcycle. The starting magneto mainly comprises a flywheel which is arranged on a crankshaft; magnetic steel is arranged in the flywheel, and a stator iron core, a starting winding and a generating winding are arranged on a motor base which is arranged on a crankshaft housing. The utility model is characterized in that magnetic steel of a Hall sensor is uniformly distributed on the bottom plane of the flywheel, and the Hall sensor is arranged on a base at a position corresponding to the track of a rotating shaft of the flywheel. The utility model can overcome the defects of large starting noise, short service life, etc. caused by a carbon brush and a commutator, and can improve the performances of ignition and lighting of a motorcycle at low speed.
Description
The utility model relates to a kind of motorcycle and starts, generates electricity with brushless, permanently and igniting integrated magnetoelectric machine.
The operation principle of starter magneto is that starting and generating winding are fixed together, and rotor directly is connected with the bent axle of engine.Owing to save transmission mechanism and freewheel clutch, thereby effectively simplified the structure of electric starting system and lubricating system, reduced the transmission power loss, improved system reliability, engine structure also is optimized.Yet the starter magneto that uses is still continued to use traditional working principle at present, and starting is realized by carbon brush one commutator, thereby has shortcomings such as noise is big, carbon brush serious wear.
The purpose of this utility model is to provide a kind of motorcycle started with no brush magneto.This starter magneto has not only overcome a series of problems of being brought by carbon brush and commutator, and can make engine and light, safety signal system performance be improved significantly.
For achieving the above object, the utility model is realized by following proposal.Mainly comprise the flywheel that is installed on the bent axle, its inwall is provided with magnet steel, being contained on the motor base on the crankcase under the flywheel shell stator core is installed, be wound with starting on the iron core, the generating winding, and be installed in sensor circuit board and external control circuit above the base, the started with no brush magneto of the electronic circuit board of drive circuit, it is characterized in that: the magnet steel that evenly is distributed with Hall element in the whole lower surface of flywheel shell, rotational trajectory place, flywheel casing lower end corresponding with it on the base of motor is provided with Hall element, the starting winding is three-phase to six phase, and the generating winding is single-phase or three-phase; Drive circuit is full-bridge or half-bridge control.
Above-mentioned Hall element magnet steel number is three to six, and corresponding Hall element is three to six.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model reversing control system schematic diagram.
1 bent axle among the figure, 2 stator coils, 3 stator cores, 4 triggers, 5 trigger supports, 6 line trigger signals, 7 motor bases, 8 sensor circuit boards, 9 Hall elements, 10 transducer magnet steel, 11 magnetic steel of motor, 12 flywheel shells, 13 control circuits, 14 drive circuits.
The utility model realizes that the course of work of started with no brush is:
After the driver presses starting button, the Hall element that is positioned at a certain transducer magnet steel magnetic field is exported a level signal to corresponding with it control circuit, this phase control circuit is exported a voltage control signal immediately, make this start the winding energising mutually by power driving circuit, make motor begin to rotate.In the rotation process because three Hall elements alternately are under the magnetic field that the transducer magnet steel produced, therefore control each start winding wheel flow-thru electrode mutually, thereby make motor continue to rotate.Because control circuit has interlock function, make any time that the energising of one phase winding only be arranged.
The utility model can overcome not only that the cranking noise that brought by brush and commutator is big, electromagnetic interference, commutation spark, wear of brush are serious, a series of problems such as poor reliability, and igniting and illumination performance can effectively improve motorcycle low speed the time.
