Calibration method according to the present invention schematically explains in Fig. 4.The top half figure of Fig. 4 is with mechanical degree solution
Say rotary transformer position, and the lower half portion figure of Fig. 4 illustrates the corresponding power supply to each phase.It is noted that
Term " mechanical degree " refers to that rotor is orientated (as unit of degree) relative to the position of full rotation (from 0 degree to 360 degree).Scheming
In 4, each phase 12-15 is powered in order first, by this method, motor 1 by rotor 3 relative to the silent of stator 2
Recognize in position and starts.This is in Fig. 4 by sequentially to phase(13), phase(14) and phase
(15) power supply is to reach.In the lower half portion figure of Fig. 4, phase 13 is powered by signal 41.Power supply signal 42 arrives phase
The line that turns of the power supply in stage 14 is explained in the lower half portion figure of Fig. 4 by 41 '.After power supply signal 42, phase
(15) it is powered by power supply signal 43.Thus, phase 13,14 and 15 is powered according to priority respectively, and rotary transformer
Position is explained in the top half figure of Fig. 4.As can be appreciated that, because rotor 3 is opposite when starting calibration method
In the relative position of stator 2 may be unknown, so the magnetic pole of the stator 10 of very possible rotor 3 will complete misalignment or with quilt
The magnetic pole of the stator of power supply phase is at least deficiently aligned, so that rotor 3 will not be by phase rank relative to the position of stator
The influence or almost unaffected of the power supply of section.This is explained in Fig. 4 by position 51.Power supply signal 41 is applied to the second phase
The position stage 13.The second phase stage 13 is equally again powered signal-powered period by power supply signal 45 later.It is corresponding
In the position of power supply signal 45 be the position 55 explained in the top half figure of Fig. 4.As can be seen, rotary transformer
The initial position 51 and rotary transformer position 55 presented when the second phase stage 13 is powered via power supply signal 41
Entirely different, rotary transformer position 55 corresponds to the power supply signal 45 being equally powered to same phase 13.In Fig. 4
In, this is because calibrating sequence start during rotor 3 rotor-position be it is unknown and with correspond to the second phase stage
The fact that the insufficient alignment of 13 magnetic pole of the stator, is caused.Therefore, by via power supply signal 41 to the second phase stage power,
Rotor-position will not move and rotary transformer provides back position 51 to controller.As can be appreciated that, position 51 is not
It will accurate location associated with any phase.In order to overcome the problems, such as the position 51 about inaccuracy explained in Fig. 4,
The first part of calibration method includes the power supply signal sequence of the sequence of power supply signal 41,42 and 43.By with indicated sequence
Column are to execute, phase、With(respectively 13,14 and 15) are powered by power supply signal 41,42 and 43.This will lead to
Always position of appearing 53 of rotor 3 when receiving power supply signal 43.Therefore, by using the homing sequence, with the 4th phase
Stage 15, associated position 53 was considered reliably.
As another optional feature, as in power supply signal 43 it can be seen that, signal include for about 0.5 second the
One low level of current (30 amperes) is the high current signal 43 " (about 100 amperes) for continuing short duration (such as 0.1 second) later.It is high
Short current signal after current impulse not only ensures that rotor 3 is firmly fixed and the 4th phase during position measures
Magnetic pole of the stator alignment position (during power supply signal 43), a possibility that it can also provide detection electrical fault.For example,
It is assumed that since there may be rotors 3 relative to, there are certain additional friction, passing through at a certain position of stator 2 for any unknown cause
Via short current impulse 43 " to the 4th phase(reference label 15) power supply, such failure can be detected, because in height
At current impulse, additional friction can be overcome and rotor can be presented and low current arteries and veins in response to high-current pulse 43 "
Rush 43 different positions.It therefore, include the first low current signal and subsequent high-current pulse for telecommunications by providing
Number 43-50, can more easily detect the possible breakdown of motor.
The calibration method explained in Fig. 4 continues to carry out lag verification.During lagging verification, if rotor 3 exists
It is rotated in either direction, determines whether rotor 3 will be presented same position.For example, in phaseIt is supplied by power supply signal 43
Phase after electricityIn the situation powered by power supply signal 44, rotary transformer 20 is by position of appearing 54.If phase later
The position stageIt is powered via power supply signal 45, stator is aligned with the magnetic pole of the stator in second phase stage, i.e., from rotary transformer
20 return positions 55.Then, if phaseIt being powered via power supply signal 45, then rotor 3 will be moved into another location,
As explaining rotary transformer position 55.If to phaseAfter 13 power supplies, phaseAgain via
Power supply signal 46 is powered, then 20 position of appearing 56 of rotary transformer, and position 56 should correspond to and phase12 is related
The position 54 of connection.If position 54 and 56 is different from each other, it is determined that in phase (clockwise) or second party in a first direction
Rotor-position 3 is significantly different in the situation sequentially powered in (counterclockwise).In this case, exist depending on 3 phase of rotor
For the lag of the direction of rotation of stator 2, this is also the failure of motor 1.
As explained in Fig. 4, in lag verification lag, calibration method is by the full rotation across rotor 3 relative to stator 2
Each alignment position in phase sequentially power, such as with the position readings that obtain each position and they are deposited
Storage continues in the memory of controller.This by Fig. 4 correspond to read-out position 57,58,59 and 60 power supply signal 47,
48, it 49 and 50 explains.The complete power-up sequence for executing calibration explains in Fig. 5.Fig. 5 is actually and the phase that explains in Fig. 4
With figure, but Fig. 5 includes that all positions to rotor 3 relative to stator are powered.All positions all by time
It goes through and after the reading of rotary transformer 20 stored, rotor 3 has been completed complete rotation.As can be appreciated that, because
Complete rotation is completed for rotor, so there is the angle of the first coil 28 determined from rotary transformer 20 at certain point
Spend the zero crossing of position.This is for example explained at position 70.Position 70 can for example return close to 360 degree position readings or
Position readings more than or equal to 0 degree.The zero crossing of rotary transformer position is recorded to prevent the rotary transformer in
Reading error is important.
