Operation principle, while implementing this programme as needs, first start this control system, whole speed regulating device are in standby condition, according to working machine, need to send instruction by control cabinet, starting main motor drives splined shaft to rotate by shaft coupling 9, it is arranged on the first sliding conductor dish 50 in the conductor disc 5 on splined shaft, the second sliding conductor dish 51 is gone up also run-in synchronism in situ, now conductor disc 5 is away from magnet disk 4, the rotating speed that main motor detected when second speed transducer 18 is when no-load running is to the rated speed of motor, control cabinet sends the instruction that starts servomotor, starting servomotor 16 drives the double threaded screw sprocket wheel 8 and 11 of the left-right rotary on air gap adjusting device 6 to rotate by master's the first sprocket wheel 8 being arranged on the reductor 15 on servomotor 16, now due to the rotation of screw rod, cause the first sleeve 60 and the second sleeve 61 to make axial separating action, its first sleeve 60 drives the second sliding conductor dish 51 in conductor disc 5 to draw close to magnet disk 4 along axis, and the second sleeve 61 also pulls to magnet disk 4 by pull bar by the first sliding conductor dish 50 rim axis in conductor disc 5, when two conductor disc 5 are synchronously drawn close and when more and more nearer to magnet disk 4, the magnetic line of force due to the first sliding conductor dish 50 of conductor disc 5 and the copper dish of the second sliding conductor dish 51 do cutting magnet disk 4 magnets, thereby can correspondingly produce induced current on the first sliding conductor dish 50 of conductor disc 5 and the second sliding conductor dish 51, the magnetic field interaction of the magnet of installing in the induced field that this induced current produces on the first sliding conductor dish 50 of conductor disc 5 and the second sliding conductor dish 51 and magnet disk 4 can produce electromagnetic torque, when electromagnetic torque increases to when being enough to overcome working machine and starting required torque, magnet disk 4 starts slowly to rotate, along with the first sliding conductor dish 50 of conductor disc 5 and the air gap of the second sliding conductor dish 51 and magnet disk 4 more and more less, the electromagnetic torque interacting can be more and more stronger, its shaft coupling being connected with load end 1, supporting disk 2, the combination of magnet disk 4 can at the uniform velocity accelerate to the specified speed of working machine, according to the starting characteristic instruction of control cabinet, control the running speed of double threaded screw and just can control the speed that conductor disc 5 moves, thereby just controlled the rate of change of the coupling air gap of conductor disc 5 and magnet disk 4, magnet disk 4 on load end working machine main shaft just can accelerate to the speed that working machine needs flexibly like this, thereby met the characteristic of large rotating inertia equipment requirement soft start, the vibration equipment of avoiding large rotating inertia equipment to cause due to instantaneous acceleration, the infringement that during with startup, impulse current causes motor winding.
Be arranged on First Speed transducer 17 on load end and in time monitoring the speed of mainshaft of load end working machine, after load end has moved, in the time of the speed of mainshaft of the working machine of load end need to being adjusted to a certain speed as technique, can be by the transducer of being responsible for monitoring process parameter on electric cabinet (as pressure, flow sensor) by control signal (the technological parameter upper lower limit value presetting), from trend servo controller, assign the instruction of this speed governing velocity amplitude, now servomotor 16 starts to start according to instruction, according to aforesaid action, conductor disc is done to suitable axial displacement (or drawing close or separation), to magnetic induction air gap is adjusted to suitable distance, to change the speed of magnet disk 4, reach the demand of process parameter value, when its speed being detected and reached the required speed of technological parameter as load end First Speed transducer 17, when sensors A has reached the required rate signal of technological parameter (parameter franchise is adjustable) to electric cabinet output speed, servomotor quits work, between conductor disc 5 and magnet disk 4, remaining the required suitable magnetic coupling air gap of technological parameter, thereby keeping the speed of load end in stable state.
While working as stopped load end working machine, can carry out in two ways, can be with the stop button manually booting on electric cabinet, also can by the interface transmission on electric cabinet, assign the signal that shuts down by Central Control Room, when electric cabinet is received stop signal, servo controller is controlled servomotor 16 and is started, by the drive sprocket on reductor 15 output shafts, the sprocket wheel on the screw rod of two double end left-right rotaries 8 and 11 is rotated, sleeve B on air gap adjusting device 6 pushes the C dish in conductor disc 5 to leave to the left direction of magnet disk 4 by pull bar, and the first sleeve 60 on air gap adjusting device 6 pulls to right side by the second sliding conductor dish 51 in conductor disc 5, leave magnet disk 4, in this process, the first sleeve 60 and the second sleeve 61 are mutually close, and conductor disc is left gradually, the air gap that is now coupled can become large gradually, magnetic flux density dies down gradually, the torque that magnetic induction produces also diminishes thereupon, the speed of magnet disk 4 also decreases, until load end working machine speed reduces to zero or the needed speed of technological parameter while meeting, when the speed that load end detected by being arranged on the speed monitoring sensors A of load end has dropped to set point, electric cabinet starts the execution instruction out of service of main motor, by control system, controlling main motor stops.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and scope are limited; do not departing under the utility model design concept prerequisite; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model; all should fall into protection range of the present utility model, the technology contents that the utility model is asked for protection is all documented in claims.
