Magnet, induction coil, master controller, motor, load, signal conversion detection circuit, alarm module etc..Pass through electromagnetic induction principle
Realize that load occurs the abnormal state detections such as deviate, load and motor rotation are asynchronous with motor axis connection.
Example shown in referring to figure 1, figure 2 and figure 3 is load and motor shaft link position among induction coil, other each
The Action Specification of component is as follows.Gray scale sector portion mainly illustrates magnet shape, special-shaped magnet relative motion meeting in Fig. 2 and Fig. 3
Lead to magnetic flux change.
Permanent magnet staggered relatively：Magnetic field is established, when load occurs not with motor axis connection abnormal phase to permanent magnet is placed
It is synchronous, the available magnetic flux change of induction coil.
Induction coil：Detect changes of magnetic field.
Master controller：Detect induction coil induced voltage (or electric current) variation；Judge whether motor and load connection are normal；

Alarm：Prompting feedback is carried out to abnormal conditions, user is notified to handle.
Specifically, the application environment and machine system that motor and load need to dismantle are as long-time service bring loads not
Be reliably connected, specific to configuration aspects show as fixed structure failure, connecting portion there is relative displacement etc., can divide following several
State：
Normal operation state：Connecting portion is good, and load links with motor coaxle.
Run semi-connection state：Connecting portion is abnormal, and appearance position is mobile, and there are asynchronous with motor rotation for load.
Run trip status：Connecting portion is abnormal, and load does not link with motor coaxle.
From the law of electromagnetic induction：What when being changed by the magnetic flux of coil, whether become caused by reason
Change, induced electromotive force will be generated at coil both ends.And flux change is faster, and induced electromotive force is bigger, i.e. induced electromotive force
Size be proportional to the change rate of magnetic flux.For N circle coil, induced electromotive force calculates as follows：
E=N* Δ φ/Δ t.
Wherein, Δ φ/Δ t indicates the flux change amount in the unit time.Magnet A follows motor shaft to rotate, and magnet B is followed
Load-side rotation, it is as follows by coil flux situation：
Normal condition：It is unchanged by coil flux, coil influence electricity kinetic potential.
Half-connection：Magnet A changes with magnet B spacing L, and asynchronous rotation occur in same magnet A and magnet B, passes through
Coil flux changes, and there are induced electromotive force E1 for coil.
Trip status：Magnet A changes with magnet B spacing L, magnet A rotation asynchronous with magnet B, coil exist compared with
Big induced electromotive force E2.
By rectifying enhanced processing to coil-induced electromotive force, be converted into can collection voltages, master controller is acquired.It is logical
It crosses detection conversion voltage and judges that connection, logic are as follows：
Normal condition：Detect voltage UOperationWhen=0, it is defined as normal condition.
Semi-connection state：Detect voltage USetting 1≤UOperation≤USetting 2When, it is defined as half-connection.
Trip status：UOperation> USetting 2When, it is defined as threading off.
After master controller obtains coil-induced voltage change information, if there is half-connection, trip status, control alarm mould
Block issues prompt information, reminds user to handle, alarm module can be made of sound components, display element, issue specific sound
Ring and show specific fault code.
Optionally, magnet shape staggered relatively can be changed.Wherein, magnet shape staggered relatively shown in Fig. 2, Fig. 3
It can be circle, rectangle etc..
Such as：Staggered relatively to limit magnet positions, magnet shape can be changed.
Optionally, magnet staggered relatively can be adjusted with induction coil relative motion state, wherein the 1st shown in Fig. 1
Magnet can choose not to be servo-actuated with motor shaft rotation or fixation.
As it can be seen that the above processing method can carry out identification judgement in real time to motor transmission system key position；Load is needed
The application environment to be dismantled, transmission system are measured in real time with bring reliability is used for a long time reducing problem, to can not
It is distinguished in real time by state, improves system operation reliability.
As a result, by initiating prompt information when the connection status exception between motor and load, to prompt user timely
Processing, timeliness is good, and hommization is good.
Optionally, the alarm module 6 may include：At least one of sound components, display element.
Wherein, the sound components can be used for issuing the prompt information of the setting sound；And/or the display element,
