Description

Pure electric automobile permanent-magnetic synchronous motor rotor initial alignment method

Technical field

The present invention relates to the localization method of the rotor after the permagnetic synchronous motor assembling is accomplished, relate to pure electric automobile permanent-magnetic synchronous motor rotor initial alignment method specifically.

Background technology

At present, when pure electric automobile is controlled with permagnetic synchronous motor, be the direction vector of controlling stator three-phase current resultant magnetic field through controller.In order effectively to control stator flux vector, need accurately measure to rotor-position.Existing permanent-magnetic synchronous motor rotor initial position confirms that method is through to the energising of motor phase current, confirms initial position of rotor again after reaching the accurate location of motor rotor position; The deficiency of its existence is that control system is comparatively complicated and need Control Software to cooperate.Also having a kind of method is to utilize the saliency of permagnetic synchronous motor; Through being added the high frequency pumping electric current, motor windings realizes accurately distinguishing of original position of electric motor's rotator; But can't being applicable to, such method do not have the surface-mount type of saliency permagnetic synchronous motor; Poor for applicability to different types of motor precision, and checkout gear is complicated.

Summary of the invention

The object of the invention be to provide a kind of simple and practical, detect accurately pure electric automobile permanent-magnetic synchronous motor rotor initial alignment method efficiently

For realizing above-mentioned purpose, order of the present invention is taked following technical proposals:

Pure electric automobile permanent-magnetic synchronous motor rotor initial alignment method of the present invention may further comprise the steps:

The first step, detect permagnetic synchronous motor under six kinds of level states, the deviate between the zero-bit that is installed on the resolver on the motor shaft and the mechanical zero of motor installation;

Second goes on foot, deviate in the first step is judged: if less than preset error, the mean value of asking for six deviates is as original position of electric motor's rotator; If greater than preset error, inspection permagnetic synchronous motor outlet order repeats above step again.

Beneficial effect of the present invention and advantage mainly are presented as:

1, detection method is simple and practical, only need install the resolver that can send U phase, V phase, W phase signals additional and can solve the AC permanent magnet synchronous motor control system and power on for the first time and can not accurately measure the problem of rotor-position;

When 2, detecting, motor need not test-bed, just can detect;

3, checkout equipment is simple, as long as switch and contactor group need not frequency converter and electric machine controller and just can detect;

4, accuracy of detection is high, utilizes this method initial alignment error maximum to be no more than ± 5 degree electrical degrees;

5, judge through certain logical relation, can detect in proper order the motor outlet.

Description of drawings

Fig. 1-1, Fig. 1-2, Fig. 1-3, Fig. 1-4, Fig. 1-5, Fig. 1-the 6th, the U phase of motor, V phase, the state diagram of W phase signals.

Fig. 2 is that the initial position of motor detects schematic diagram.

Embodiment

Pure electric automobile permanent-magnetic synchronous motor rotor initial alignment method of the present invention is at first installed resolver in advance when motor is made, detect with its output U phase, V phase, W phase status signal.During monitoring, the U phase that resolver is seen off, V phase, W phase status signal one have six level states, like Fig. 1-1 to shown in Fig. 1-6; 01X, 0X1, X01,10X, 1X0, X10, it is interval between six grades characterizing the electrical angle of motor rotor position, each interval is 60 ° of electrical degrees; Among Fig. 1; 1 represents high level, and 0 represents low level, and the X representative is unsettled.

Shown in Fig. 1-1; State 01X representes that the U of resolver is connected with the negative pole of DC power supply is, and V is connected with the positive pole of DC power supply is, and W is mutually unsettled; The electric current 20A-50A of DC power supply is; Conduction time<10s, treat that the permagnetic synchronous motor axle stops operating after, measure the motor rotor position value.

Detection method is as shown in Figure 2.At first detect six position deviations under the level state, should equate in theory, but because the asymmetry of motor operation has deviation between six values, within predefined error range, then averaged is the motor initial position as if deviation; If deviation outside predefined error range, is then measured failure, inspection motor outlet order is carried out initial position again and is measured.

For the motor that has only a pair of utmost point, the electrical degree that rotor turns over equates that with mechanical angle for the extremely right motor of N, the electrical degree that rotor turns over equals N times of mechanical angle.Therefore, when adopting this method to carry out rotor electrical degree location, for the extremely right motor of N, the mechanical angle that rotor turns over before accurately locating is not more than N/one of 60 degree.
