Background technology
At present, automobile-used electric-spraying fuel pump mainly to drive fuel pump work using permanent magnetic brush DC motor both at home and abroad
Make, electric-spraying fuel pump permanent magnetic brush DC motor is changed using the machinery that radial or end-surface type phase changer and brush are formed
Phase, its principle is：Make unidirectional current pass through brush and phase changer entrance armature winding, produce electric current, armature mmf and main field phase
Interaction produces torque, drives the pump housing to run up, however, due to there is depositing of these contact part brushes and phase changer
There is following defect in this motor：Complex structure, unstable, fault is many, short life（The electric oil jetting pump longevity best at present
Life is at most at 8000 hours about）, due to phase changer and brush, the carbon dust producing and copper powder in operation friction have a strong impact on
The cleaning of fuel, reduces the service life of vehicular engine, and the current whole world all for saving petroleum-based energy, reduces automobile row
The pollution of air of being rivals in a contest gives people the harm that class is brought, and with mixed type fuel instead gasoline, but mixed type fuel is straight to there being brush permanent magnetism
There is larger corrosion in the diverter in stream motor and shunt welding.Also minority automobile is had to adopt the brushless EFI of position sensor at present
Oil pump, position sensor is brushless, and electric oil jetting pump is the phase meta being necessarily mounted at stator winding using rotor-position sensor
Put, the position signalling of rotor magnetic steel magnetic pole could be converted into the signal of telecommunication, then go to control stator winding commutation, therefore, rotor
Position sensor is necessarily mounted inside direct current generator, and the presence of position sensor increased weight and the size of motor, no
Beneficial to miniaturization, and position sensor also requires that precisely with the alternate position of stator, otherwise can cause the on-stream deadlock of motor, and
Brushless fuel pump rotor wiring only has a kind of mode, if reverse wiring, leads to fuel oil air pump inoperative it is therefore necessary to provide one
Kind can positive and negative wiring fuel pump.
