Description
Technical field
The invention belongs to starting, technical field of generators, be specifically related to a kind of two-in-one permanent magnet brushless electomotor with internal rotor that on motorcycle, uses.
Technical background
The starting of the starter magneto that uses on the motorcycle all is to realize by carbon brush one commutator at present, has shortcomings such as noise is big, electromagnetic interference, commutation spark, carbon brush serious wear.Chinese patent 00242041.4 discloses a kind of " motorcycle started with no brush magneto ", though can overcome the shortcoming that brush and commutator bring, but also come with some shortcomings: mainly be to adopt external rotor internal stator structure, the number of turn of coil windings is subjected to spacial influence, can not design arbitrarily, exist starting current big, commentaries on classics is turned round little, has the stall phenomenon during starting.Therefore the big type of high-power compression ratio need be provided with depressurized system, complex structure.In addition, its rotor is the conventional structure that adopts, and the magnetic field of formation is not too even, influences the outer mechanical property of motor.
Summary of the invention
The present invention is directed to the prior art above shortcomings, purpose is to provide a kind of two-in-one permanent magnet brushless electomotor with internal rotor, adopts the internal rotor outer stator structure, realize brushless commutation, simple in structure, starting torque is big, starting current is little, eliminates cranking noise, and is safe and reliable.
Technical scheme of the present invention is as follows:
Two-in-one permanent magnet brushless electomotor with internal rotor comprises rotor, stator, actuating coil and power coil, external control circuit and drive circuit.Rotor is installed on the bent axle of engine, and rotor is installed stator core outward, actuating coil CD, CE, CF and power coil A, B is arranged, external control circuit and drive circuit in the stator core.The skeleton shell of stator core is connected with engine, and the outer face of skeleton shell is equipped with firing pulse transducer U
0, corresponding to the ignition timing projection of installing with rotor coaxial, skeleton shell inner face is installed Hall element G, H, I successively with circumferencial direction 120 degree angles, and the face that rotor is corresponding is with it installed Hall element magnet.
The initiating signal of this motor divides two-way; one the tunnel connects starter relay and current foldback circuit, is connected to the C end of actuating coil CD, CE, CF, and one the tunnel connects controller; connecting Hall element G, H, I, power coil A, B power to electrical equipment or storage battery after connecing switchmode rectifier.
The magnetic pole of the rotor of this motor is the beak shape, is made of pressing magnet steel in the middle of two corresponding beak-like magnet, and one side is that the N utmost point simultaneously is the S utmost point.
The operation principle of this motor is as follows:
When pressing the motorcycle starting button, initiating signal divides two-way: the one tunnel connects starter relay, makes electric current arrive the C end of actuating coil CD, CE, CF, and one the tunnel connects controller, makes Hall element G, H, I energising.When epitrochanterian Hall element magnet pointed to certain Hall element, certain transducer was subjected to magnetic field induction, produced a signal simultaneously, passed to controller, and corresponding actuating coil and ground are connected, and actuating coil produces magnetic field and makes rotor rotation.Because Hall element G, H, I with 120 jiaos of arrangements, so after rotor has changeed 120, make and face certain Hall element connection mutually, after the adjacent thereupon actuating coil energising, continue to promote the rotor rotation on circumference, so drive engine crankshaft and rotate starting continuously.
After engine start, because rotor is that permanent magnet makes, it rotates cutting magnetic field, makes power coil A, B produce electric current, and electric current is converted to direct current after being sent to switchmode rectifier, supplies with storage battery and the use of other electrical equipment.
Advantage of the present invention is:
1, this motor has used the internal rotor outer stator structure, makes the coil windings number of turn on the stator not be subjected to spacial influence, can be designed into as required can make engine smoothly the required power of starting, change and turn round and reach the electric current that is mated.Therefore guaranteeing under the prerequisite simple in structure that the starting torque of motor is increased, and starting current reduces.
2, cancel carbon brush one commutator of traditional structure, eliminated the starting noise, safe and reliable, prolong working life.
3, the magnetic pole of the rotor of this motor is designed to the beak shape, can make the magnetic line of force between stator and rotor, become Sine distribution in the air gap, form approximate uniform magnetic field, make the AC electromotive force of stator coil be similar to sinusoidal waveform, optimized the outer mechanical property of this motor.
