Abstract
The invention provides a special rotor with an improved Hall output waveform for a motor of an electric tricycle and relates to a motor. The rotor comprises two kinds of rotor silicon steel sheets, a plurality of dovetail-shaped magnetic shoe fixing parts are uniformly distributed and manufactured on the outer circumference of one kind of the rotor silicon steel sheets and used for fixing permanent-magnet shoes, the rotor silicon steel sheets of the other kind are rotor silicon steel sheets without magnetic shoe fixing parts, a cylindrical rotor is arranged at one end of a Hall and formed by stacking the rotor silicon steel sheets without magnetic shoe fixing parts, and a clutter isolation space is formed among the rotor silicon steel sheets without magnetic shoe fixing parts and the Hall. When a rotor component of the motor rotates in a stator component, only permanent-magnet shoes different in polarity slide through the Hall, output signals of the Hall are generated by the permanent-magnet shoe, clutter generated in the output signals of the Hall due to the dovetail-shaped magnetic shoe fixing parts disappears, three-phase current inputted into a winding coil by the controller is stable, the motor works stably, the service life of the motor is prolonged, and repair of the motor is reduced.
Description
Technical field
The present invention relates to a kind of motor, be specifically related to a kind of electro-tricycle motor special and there is the rotor that improves Hall output waveform.
Background technology
The cylindrical rotor that electro-tricycle Special motor rotor assembly is made by rotor silicon steel sheet stack pressing formation and the permanent magnetic tile of different magnetic poles form, (outer edge of permanent magnetic tile is respectively N and the S utmost point); Epitrochanterian dove-tail form magnetic shoe fixture is fastened on a watt type magnet steel on rotor, rotor assembly is arranged in stator module, when rotor assembly rotates, permanent magnetic tile is when turning over Hall, Hall can produce a signal and be input to the controller of motor, the signal that controller produces according to opposed polarity permanent magnetic tile, respectively to the three different electric currents in phase winding output phase angle of motor, runs well motor.Because dove-tail form magnetic shoe fixture material is silicon steel, can be magnetized by ferromagnetic permanent magnetic tile, when the dove-tail form magnetic shoe fixture after magnetization turns over Hall, Hall also can produce a strong noise signal that is different from magnetic shoe signal, this strong noise signal is input to after controller, controller, owing to being subject to the interference of strong clutter, is given motor winding output non normal phase electric current; The input current of motor winding is unstable, causes motor abnormality shake, affects the power output of motor, greatly reduces motor useful life.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of electro-tricycle motor special and there is the rotor that improves Hall output waveform, the one end that cylindrical rotor is positioned to Hall is formed by the rotor silicon steel sheet stack without magnetic shoe fixture, without forming clutter insulating space between the rotor silicon steel sheet of magnetic shoe fixture and Hall, stop to produce strong noise signal.
The present invention is achieved through the following technical solutions: a kind of electro-tricycle motor special has the rotor that improves Hall output waveform, and the rotor of motor is comprised of rotor silicon steel sheet, permanent magnetic tile and armature spindle.Described rotor silicon steel sheet has multi-disc, after the stack of multi-disc rotor silicon steel sheet, with bearing pin, fixes, and goes into cylindrical rotor, and described cylindrical rotor endoporus is fixed on armature spindle.Many dove-tail form magnetic shoe fixtures of the uniform making of rotor silicon steel sheet cylindrical, described permanent magnetic tile is inserted between adjacent two dove-tail form magnetic shoe fixtures.The stator silicon steel sheet of motor is the tubular body that has the silicon steel sheet stack of stator line embedding groove and rule notch to form with multi-disc punching press, and rotor is arranged in the endoporus of described tubular body.Winding wire bag embeds in line embedding groove, and then carves the shutoff of rule notch with groove.Hall is arranged on one end of tubular body endoporus by Hall support; Hall and permanent magnetic tile are adjacent.It is characterized in that: described rotor silicon steel sheet has two kinds, many dove-tail form magnetic shoe fixtures of the uniform making of a kind of rotor silicon steel sheet cylindrical wherein, another kind of rotor silicon steel sheet is the rotor silicon steel sheet without magnetic shoe fixture.One end that described cylindrical rotor is positioned at Hall is formed by the rotor silicon steel sheet stack without magnetic shoe fixture, without forming clutter insulating space between the rotor silicon steel sheet of magnetic shoe fixture and Hall.
Good effect of the present invention is: the one end that is positioned at Hall due to cylindrical rotor is superposeed by the rotor silicon steel sheet without magnetic shoe fixture, without forming clutter insulating space between the rotor silicon steel sheet of magnetic shoe fixture and Hall, while turning over Hall without the rotor silicon steel sheet of magnetic shoe fixture, only have the magnetic shoe of opposed polarity to slip over Hall, the output signal of Hall also can only be produced by magnetic shoe, in Hall output signal, do not have because of dovetail generation clutter, the three-phase current of controller input motor is stable, the useful life of improving motor.
