Describe in detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention,
It is not intended to limit the present invention.
A kind of rotor magnetic detection method of the present invention, as it is shown in figure 1, include:
Step S10, will magnetize after rotor be installed on rotary apparatus.
Typically now the rotor of external rotor electric machine is by iron-clad and iron-cased magnet ring, in order to survey
Whether magnetizing of preliminary operation meets the requirements, and need to magnetize the rotor after magnetizing test, first
First the rotor of the number of filling magnetic is installed on the rotary apparatus of test machine, and rotor is fixed.
Step S20, rotary apparatus rotor driven rotate, and make induction system produce faradism
Kinetic potential, and induced electromotive force signal is passed to controller.
Concrete, rotor to be installed after being fixed on rotary apparatus, rotary apparatus detects,
Detecting that rotor has been installed in place, will send control signal to controller, controller receives control
Signal processed, and as displacement commands, rotary apparatus is displaced to suitably, and rotary device is selected in drive
Rotating, according to law of magnetic induction, corresponding induction installation can produce induction electromotive force, sense
Answer device that induced electromotive force signal is passed to controller.
Step S30, controller, according to the signal of the induction electromotive force received, generate faradism
The numerical value of kinetic potential, and compare judgement with the scope of standard figures, whether magnetizing reaches
Requirement, and will determine that the output system that result exports.
The signal of induction electromotive force that concrete controller will receive, is processed computing, raw
The induction electromotive force becoming each magnetic pole of rotor must be worth, and enters with the standard value of setting in controller
Row compares, and described standard value is a value range, such as, standard can be set to 3.5v-4.5v
Such value range, and the big I of standard value is next according to concrete product according to staff
Set.Further, controller judges according to the result of comparison, and will determine that result passes
It is delivered to output system.
The testing result of controller is judged knot by display screen output by step S40, output system
Really.
Concrete, described output system is by being processed output result, and will process
After result by display screen display output to staff, staff sentences according to display result
Whether rotor magnetizes meets the requirements.
Concrete, described rotor magnetic detection method, wherein, step S2 as shown in Figure 2
Specifically include:
Induction apparatus on step S21, rotary apparatus senses rotor installation, will give control
Device processed sends rotor installation signal.
After staff mounts the rotor on rotary apparatus, on rotary apparatus induction apparatus
Sense that rotor to after being installed on rotary apparatus, and is simply locked by rotor,
Then the signal of rotor installation is sent to and rotary apparatus communication connection by rotary apparatus
Controller.
Step S22, controller receive rotor installation signal, will send rotary apparatus
Movable signal.
When controller receives what rotary apparatus passed over, the signal fixed installed by rotor
After, controller can send corresponding displacement signal to rotary apparatus, and preferred displacement signal is arteries and veins
Rushing signal, described pulse signal is usually used in driving the actuator such as motor or servomotor, logical
Cross control pulse frequency and can control the parameters such as the rotating speed of actuator, the anglec of rotation easily,
Owing to pulse signal control mode is simple and reliable, it is widely used.
After step S23, rotary apparatus receive displacement signal, with rotor movement to sensing dress
The correspondence position put, subsequent signal is to controller.
After described rotary apparatus receives the pulse signal that controller sends, the execution of rotary apparatus
Mechanism is according to identifying pulse signal, and the rotor being rotated on device according to pulse signal is carried out
Displacement, after being displaced to the position that system is arranged, rotary apparatus can send to controller, rotor
It is moved into specifying position to obtain signal, it is simple to controller carries out the determination of next step action.
Step S24, controller receive rotary apparatus move to induction installation move to sensing dress
After the correspondence position signal put, the electric rotating machine rotor driven on rotary apparatus is driven to rotate.
After controller receives the position signalling that rotor arrives system setting, rotation dress can be sent
Put the control instruction carrying out rotating, the actuator rotor driven on rotary apparatus select
Dress, described rotation instruction is pulse command.
Step S25, magnetize after rotor sense of relative induction device under the drive of rotary apparatus
Answering coil to rotate, induction coil produces induction electromotive force, the induction electric that induction installation will produce
Gesture passes to controller.
The position arranged in system when rotor rotates, and the position that system is arranged just makes rotor
With induction coil mutually can answer line and produce induction electromotive force, now by rotation by cutting magnetic induction
The rotor turned mutually rotates with fixing induction coil, produces induction electromotive force, induction electromotive force
Sensed device, is sent to controller with the form of electromotive force signal.

C specifically includes:
Step S31, controller, according to the signal of the induction electromotive force received, generate rotor
The induction electromotive force numerical value of each magnetic pole.
Controller is according to the induced electromotive force signal received, by the public affairs of controller internal reservoir
Formula computing draws the induction electromotive force of each magnetic pole of rotor, the mistake due to rotor and when magnetizing
Difference, can cause the induction electromotive force of each magnetic pole also to have difference.
Step S32, controller are by the induction electromotive force numerical value generated and the mark of setting in controller
The electromotive force numerical value contrast of quasi-value, and judge whether the numerical value of the induction electromotive force of rotor meets
Whether requirement, i.e. magnetizing meet the requirements.
The standard value that controller will be arranged in the induction electromotive force of each magnetic pole of rotor, with controller
Compare one by one, according to comparing result, controller judges whether magnetizing of rotor conforms to
Ask.
Step S33, controller will determine that consequential signal output system.
The result of determination of rotor test is exported defeated with high level and low level mode by controller
Going out system, wherein, high level represents test result and meets the requirements, and low level represents and do not meets
Requirement.
Concrete, described rotor magnetic detection method, wherein, the most described step
D specifically includes:
Step S41, output system receive the judging result signal of controller output, if judging
Consequential signal is satisfactory high level signal, then output system is by satisfactory high level
Signal, is converted into the OK pattern that display shows.
Step S42, output system receive the judging result signal of controller output, if judging
Consequential signal is undesirable low level signal, then output system is by undesirable low
Level signal, is converted into the NG pattern that display shows.
In sum, the having the beneficial effect that by filling of a kind of rotor magnetic of present invention detection method
The induction electromotive force that magnet rotor produces with induction coil, and automatic and the electromotive force value preset model
Enclosing and compare, and whether this rotor of automatic decision magnetizes no and requirement, this method of testing is simple
Fast, it is suitable for batch testing, and tests accuracy rate height, overcome prior art and rotor is filled
The shortcoming that magnetic tester is complicated, it is possible to increase the yield magnetized, and then improve motor product quality,
Reduce enterprise and do over again the loss brought because of the bad customer complaint caused that magnetizes.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
