Description
Technical field
The present invention relates to a kind of electric locomotive, especially a kind of permanent-magnet brushless DC electric machine stringing formula bi-motor car.
Background technology
Permanent-magnet brushless DC electric machine is a kind of New Type of Direct-current Machine got up with the development of electronic technology；Permanent magnetism
Brshless DC motor has the classical threephase stator similar to induction machine, and its rotor surface is equipped with permanent magnet, and commutation is turning
Electronically completed on sub- position of magnetic pole, therefore magneto is alternatively referred to as electronic commutation motor；Stator is generally thin by silicon steel
Piece is made, and in stator winding insertion groove, makes distributed stator winding；Because motor gas-gap magnetic field is produced by rotor permanent magnet
Raw, so rotor field is constant；Magnetizing and its being distributed on rotor for permanent magnet is, by selection, can to cause anti-
Electromotive force（The voltage that stator winding senses by rotor rotation）Waveform be it is trapezoidal, thus can use have square wave
（Square wave）Electric current motor, generate high torque (HT) rotating excitation field.
The square wave applied due to permanent-magnet brushless DC electric machine（Square wave）Voltage is easily produced with respect to other control modes, institute
Also easily realized with the control of motor and driving, but must be known by rotor magnetic pole position at some（Electricity）Angle, could allow institute
The square-wave voltage of application aligns with counter electromotive force, realizes the drive control to motor, from this point of view permanent magnet brushless dc
Machine is properer PM Square Wave torque motor.
Counter electromotive force and commutation action align be it is very important, only in this way, motor could as direct current generator with
Highest efficiency is run.
The basic structure of permanent-magnet brushless DC electric machine：Permanent-magnet brushless DC electric machine is main by motor body, electric machine controller
（The electronics commutation circuit of voltage-type DC-AC inversions driving running control circuit composition）With the three part groups such as rotor-position sensor
Into.Permanent-magnet brushless DC electric machine body：The main motor by stator core, stator winding, p-m rotor, rotating shaft and supporting stator
Shell is constituted.Electric machine controller：The effect of electric machine controller is the driving operational control for receiving motor（Startup, speed governing, commutation,
Stop, braking）Signal, with drive control motor, and the rotor magnetic pole position signal that rotor-position sensor is exported is solved
Tune, pre-amplification, power amplification, then go to trigger final power transistor, armature winding is powered by certain logical program, protect
Demonstrate,prove the reliability service of motor.Rotor-position sensor：Rotor-position sensor be realize the important component of contactless commutation, be nothing
One key component of brushless motor.Rotor-position sensor plays measure rotor magnetic pole position letter in brshless DC motor
Number and tach signal effect, provides correct commutation information for logic switching circuit, i.e., by the position letter of rotor permanent magnet magnetic pole
Number electric signal is converted into, goes to control stator winding commutation.
Permanent-magnet brushless DC electric machine typical feature：（1）Motor rotary inertia is small, response fast, with torque per unit volume it is high,
Torque ratio of inertias is small；（2）Without electrical excitation, with higher efficiency and power factor；（3）P-m rotor does not generate heat, heating part
Divide on stator, radiating condition preferably, relative can take higher electromagnetic load；（4）Air gap main flux is by rotor permanent magnet
What body was produced, the electric current of stator winding can design linear with the torque produced, and control performance is more preferable；（5）There is no carbon
Brush and mechanical reversing mechanism, improve the reliability of motor；（6）Three-phase fully-controlled（Inversion）Running control circuit changes direct current
Powered into alternating current to motor, different from general inverter, its output frequency is not separately adjustable, and is controllable by rotor
Position of magnetic pole signal, equivalent to one " autocontrol inverter ", due to the rotating speed using rotor magnetic pole position signal control motor,
The frequency and motor speed of permanent-magnet brushless DC electric machine input current is set to remain synchronous, motor and inverter will not be produced and shaken
