Fig. 2 is a kind of method flow of the control method of the motoring drive system of full-rotating rudder paddle provided by the invention
Figure, the control method uses the motoring drive system in above-described embodiment, as shown in Fig. 2 the control method includes：
Three step 201, control revolution driving motors proceed by direct current band-type brake.
Wherein, direct current band-type brake refers to：Direct current is passed through in two-phase stator winding.
After stopping providing alternating current to revolution driving motor, the rotor of revolution driving motor can continue frequency converter because of inertia
Rotation, direct current band-type brake is now carried out, the input dc power in two-phase stator winding, can form stationary magnetic field, rotor is quiet immediately
Only rotated in magnetic field and produce induced-current, so as to be acted on by electromagnetic force, rotating speed is gradually reduced.
It should be noted that when three revolution driving motors of control carry out direct current band-type brake, the electric current for the direct current being passed through is big
It is small identical with the size of the rated current of three revolution driving motors respectively.
Specifically, control full-rotating rudder paddle revolution before, frequency converter 40 it is electric, if obtain it is electric after the self-test of frequency converter 40 just
Often, then can automatic start, now frequency converter 40 respectively into three revolution driving motors input current be I direct current, make three
Platform revolution driving motor carries out direct current band-type brake.
Three step 202, control revolution driving motors stop carrying out mechanical hatching gate；
Wherein, mechanical hatching gate refers to：When revolution driving motor switches on power, the electromagnetic brake coil in brake also obtains
Electricity, armature adhesive, overcoming the pulling force of spring separates the brake shoe of brake and brake wheel, revolution driving motor is normally transported
Turn.When revolution driving motor dead electricity, also dead electricity, armature separate electromagnetic brake coil under spring tension effect with iron core, and
The brake shoe of brake is set tightly to embrace brake wheel, revolution driving motor is braked and stalled.
Specifically, start at the time of three revolution driving motors stop carrying out mechanical hatching gate with three revolution driving motors into
Between at the time of row direct current band-type brake at intervals of t, wherein, 0.2s ＜ t ＜ 5s.In the present embodiment, t=1s.
Three step 203, control revolution driving motors stop carrying out direct current band-type brake.
Specifically, stop being passed through direct current into the two-phase stator winding of three revolution driving motors, with control, three are returned
Turn motor to stop carrying out direct current band-type brake.
It should be noted that before control full-rotating rudder paddle revolution, step 201- steps 203 perform in chronological order,
And after execution of step 203, the control method can also include：
Step 204, control full-rotating rudder paddle revolution.
Now frequency converter 40 receives the control instruction that PLC 60 is sent, and controls three to return according to the control instruction
Turn the rotating speed of motor, so as to control full-rotating rudder paddle to be turned round.
After full-rotating rudder paddle completes revolution, following steps can be continued executing with：
Three step 205, control revolution driving motors proceed by direct current band-type brake.
Specifically, when frequency converter 40 receives the halt instruction of PLC transmission, three revolution driving motors are controlled
Rotating speed be reduced to 0, and direct current is passed through into the two-phase stator winding of three revolution driving motors, to control three revolution drivings
Motor proceeds by direct current band-type brake.
Three step 206, control revolution driving motors carry out mechanical hatching gate.
Three step 207, control revolution driving motors stop carrying out direct current band-type brake.
Specifically, stop being passed through direct current into three revolution driving motors, control three revolution driving motors stop into
Row direct current band-type brake, frequency converter 40 are shut down.
It should be noted that when controlling full-rotating rudder paddle to stop revolution, step 205- steps 207 are held in chronological order
OK.
, it is necessary to first stop carrying out mechanical hatching gate before control full-rotating rudder paddle is turned round, but due to mechanical hatching gate
It is to be carried out by the action of mechanical structure, the action of mechanical structure needs certain time, and this to arrive in stopping mechanical hatching gate
Before control full-rotating rudder paddle starts revolution, interval of time is had, full-rotating rudder paddle is possible to can be in active forces such as current
In the case of rotate.And by first carrying out direct current band-type brake to revolution driving motor before mechanical hatching gate is stopped, and stopping
Direct current band-type brake is only still carried out after mechanical hatching gate, until start to control full-rotating rudder paddle revolution, due to only needing to stop to returning
Turn to be passed through direct current in the two-phase stator winding of motor, it is possible to stop direct current band-type brake at once, then be passed through three-phase alternating current
Can control revolution driving motor rotates, and so as to control full-rotating rudder paddle to turn round, is driven from direct current band-type brake is stopped to control revolution
Interval between dynamic motor rotates is short, and full-rotating rudder paddle can be avoided to be rotated under the active forces such as current.
Simultaneously control full-rotating rudder paddle stop revolution when, carry out mechanical hatching gate mechanical structure needs action one by one section when
Between can just make the brake shoe of brake embrace brake wheel to be braked, within this time, full-rotating rudder paddle is possible to can be due to inertia
Or the influence of current continues to turn round certain angle.And by before revolution driving motor carries out mechanical hatching gate, first passing through frequency conversion
Device 40 controls the rotating speed of three revolution driving motors to be reduced to 0, then carries out direct current band-type brake, can make full-rotating rudder paddle stable a certain
On angle position, then mechanical hatching gate is carried out to revolution driving motor, finally stop direct current band-type brake again, so can be in brake
Brake shoe is just braked before embracing brake wheel by direct current band-type brake, avoids full-rotating rudder paddle from being returned under the influence of inertia or current
Turn, revolution driving motor is in controllable state all the time, prevent that the rudder angle of full-rotating rudder paddle is out of control.
The present invention is by by the slippage S of three revolution driving motors1T、S2T、S3TIt is arranged to | (Sa-S1T)/Sa|≤0.05, |
(Sa-S2T)/Sa|≤0.05, | (Sa-S3T)/Sa|≤0.05, wherein Sa=(S1T+S2T+S3T)/3.So that three revolution driving electricity
