10. the static speed governing protection type of the whole interior radiation ring type permanent magnet clutch course of work:
The static speed governing protection type of interior radiation ring type permanent magnet clutch is non-contact type coupling, replaces motor with air gap and is connected with the entity between load, thereby diaxon is separated fully, allows the larger error of centralization.During electric motor starting, the rotation of conductor external rotor I and motor synchronous high-speed, because conductor external rotor I and permanent magnetism internal rotor II are contactless shaft coupling, permanent magnetism internal rotor II can not be rotated immediately.In the electric machine rotation process, the whole magnet ring of the interior radiant type of the outer conductor ring in conductor external rotor I magnetic conductor list annulus inductor and permanent magnetism internal rotor II permanent magnet produces relative rotation, alternating magnetic field produces eddy current on the sensor conductor ring outside by air gap, eddy current produces the permanent magnetic field interaction of induced field and the whole magnet ring of interior radiant type simultaneously, due to the load torque effect, passive permanent magnetism internal rotor II is still in static, after active conductor external rotor I turns over an angle, respond to the induced field in conductor loops outside it and have certain slip angle between the permanent magnetic field of dynamic load permanent magnetism internal rotor II, according to the magnetic pole two like magnetic poles repel each other, the principle that there is a natural attraction between the sexes, thereby make static poised state be broken, the size of the angle that initiatively conductor external rotor I turns over depends on the size of load torque, now from dynamic load permanent magnetism internal rotor II, can be subject to the effect of electromagnetic torque, electromagnetic torque is along with active electric machine conductors external rotor I increases with increase from the slip angle of dynamic load permanent magnetism internal rotor II, when electromagnetic torque surpasses load torque, from dynamic load permanent magnetism internal rotor II, start to rotate.Whole process starting current peak value greatly reduce and start-up time very short, realized electric machine soft starting, reduce the starting power consumption of motor and avoid causing larger rush of current.Be particularly useful for frequent motor starting and load variable load the connecting of motor and load under operating mode frequently.
After this, under the driving of motor, initiatively electric machine conductors external rotor I will with keep certain slip angle synchronous operation from dynamic load permanent magnetism internal rotor II.Thereby with dynamic load permanent magnetism internal rotor II along the direction rotation identical with electric machine conductors external rotor I.Result produces torque on the load-side output shaft, thereby the band dynamic load rotates.Realize the non contact transmission of power.Realize the moment of torsion transmission between motor and load.In when the load variable load, the static speed governing permanent magnet clutch of radiation ring type self-regulating rotary declinate, guarantee that the moment of torsion transmission is smooth.
Utilize efficient radiating apparatus simultaneously, reduce the temperature of the whole magnet ring 5 of conductor loops 4 and radiant type, guarantee that the system magnetic working is stable.
Requirement according in good time load output variable, under static state, regulate conductor external rotor I and the relative position of permanent magnetism internal rotor II on axis direction by field of conjugate action adjusting mechanism III, manual rotation internal thread adapter sleeve, due to the restriction that is subject to slide key, outer silk adapter sleeve can only move axially, thereby pulls permanent magnetism internal rotor II axially to relatively move.To change the magnetic force area of contact size between conductor external rotor I and permanent magnetism internal rotor II, realize changing the size of transmitting torque between electric machine conductors external rotor I and load permanent magnetism internal rotor II.The static speed governing protection type of interior radiation ring type permanent magnet clutch is to realize speed control by regulating moment of torsion, and area of contact is large, and the moment of torsion of transmission is large, and load speed is high; Area of contact is little, and the moment of torsion of transmission is little, and load speed is little; Motor outputs to the moment of torsion of the static speed governing protection type of interior radiation ring type permanent magnet clutch and moment of torsion that the static speed governing protection type of interior radiation ring type permanent magnet clutch outputs to load equates.Like this, we can regulate magnetic force area of contact size according to the size of output variable in the load actual moving process, change the transfer of torque size, and load torque is little, and the motor output torque is little, and corresponding power output is also little.Realize significantly energy-conservation and raising motor working efficiency of motor.
The maximum load torque that the static speed governing protection type of interior radiation ring type permanent magnet clutch can bear is determined by the peak torque of static torque characteristic, when load torque values surpasses this peak value size, will produce the step-out phenomenon.Due to the slippage principle, stall does not appear in motor.Realized the overload protection to motor.Namely permanent-magnetic outer rotor II stalling load stall, but the conductor loops 4 in conductor external rotor I still can keep motor speed constant with the radially fixedly magnetic line of force of the whole magnet ring 5 of the radiant type of air gap cutting permanent-magnetic outer rotor II, motor overload work simultaneously.Now the speed probe in intelligent protection system IV 19 can gather a process signal and pass to signal processor 20 on signal code-disc 18, through the signal processor single-chip microcomputer, processes, and then gives control signal of motor power, cuts off the electricity supply and makes motor stalling.In stoping, the static speed governing protection type of radiation ring type permanent magnet clutch is when the high speed slippage, and system heats up too high and has a negative impact.After the load overload is eliminated, reset the moment of torsion transmission that motor is realized next process.Control assurance is provided for remote motor.
The static speed governing protection type of interior radiation ring type permanent magnet clutch package unit has been realized completing smoothly of Contactless power transmission, variable speed energy saving and the action of intelligent overload protection.
Conductor loops adopts the material of magnetic conduction conduction such as copper, aluminum are done all can.
