00:05A motor rotation inverter with automatic and timed pre-inversion will be implemented.
00:11This means that when a button is pressed, it will send the activation signal to a timer.
00:15for one-way rotation, and there will be an automatic timer with another timer.
00:20For this, we start and create the power circuit, with the line power supply,
00:25line, line, and the protection line.
00:29Next comes a three-line circuit breaker for protection.
00:36A contactor in parallel with another contactor.
00:53Further along, the other contactor is located in parallel.
01:06A thermal relay.
01:18For the protection of the motor and a three-phase motor.
01:38And we installed and connected the protection line.
01:50Now we simultaneously place a contactor, and make the connection in parallel.
02:02To reverse the direction of rotation of a three-phase motor, the connection order of two of the phases must be changed.
02:07the three phases that power the motor.
02:09This reverses the direction of the magnetic fields and consequently the direction of rotation of the
02:15rotor.
02:24The protection line of the three-phase motor is yours.
02:24The line of electric things does not have to be used with a car control
02:30and consequently even less so the protection circuit.
02:55Music
03:00Now we change the names of the elements; for the circuit breaker it will be Q, for the contactor it will be named C1, the
03:07The thermal relay will be F1, the second contactor in parallel will be C2.
03:12Music
03:41Music
03:44With a normally closed thermal contact, followed by a normally closed push button, then a normally open push button,
04:02Music
04:06Also two normally closed contacts, to a coil
04:18Music
04:24And in parallel, a timer connected to the power source, and an indicator, a green lamp.
04:32Music
04:57We draw the neutral or phase line,
05:05Music
05:08Now we place a time-delay contact in parallel with a contact to perform the interlocking.
05:17Music
05:18Also, another normally closed contact,
05:27Music
05:31All of this is connected to a timer; these timers will have a 5-minute interval each.
05:39Music
05:40Music
05:47Music
05:48Music
05:51Music
06:01Music
06:02Music
06:04Music
06:24This timer will also have a time-delay contact connected in parallel to a contact, to perform the interlocking.
06:31Music
06:32Next, another normally closed contact will activate a coil.
06:39Music
06:40Music
06:42Music
06:45Music
06:47Music
06:47This coil is connected in parallel with an indicator, in this case another green lamp.
06:53Music
06:54Music
07:09And finally, we have the emergency stop indicator of another normally open thermal contact,
07:15This will activate in case of an excessively high temperature in the thermal relay protection.
07:21It will automatically stop and the engine will come to a halt, with the red indicator light on.
07:25Music
07:26Okay, we'll proceed to make the connection.
07:28Music
07:32Music
07:57Music
07:58Music
08:00Music
08:07Music
08:17Music
08:18Music
08:20Music
08:22Music
08:24Music
08:35Music
08:48Music
09:04We will change the names of the elements; the normally closed thermal contact will be named F1.
09:11Music
09:12Music
09:14Music
09:14Music
09:16Music
09:16Next, a normally closed push button called S0,
09:19Music
09:20Music
09:22Music
09:23Music
09:24Music
09:25Music
09:25Music
09:28Music
09:29In series with two normally closed contacts called C11 and C2.
09:35In series with a coil called C1.
09:39In parallel with a C10 timer.
09:52And a lamp called H1.
09:58The timer contact will be called C10.
10:06Normally open in parallel to another contact C11.
10:11In series with another contact C2.
10:15To another timer called C11.
10:19The timer contact will be called C11 normally open in parallel to another contact C2.
10:26In series with another contact C1.
10:30To another coil called C2.
10:33In parallel with an H2 lamp.
10:38And finally we have another normally open thermal contact called F1 in series with the red stop light.
10:45We will move on to the simulation.
10:46We start by activating the circuit breaker.
10:48Pressing C1 energizes the C1 coil.
10:51That is self-supporting for 13 to 14.
10:54Simultaneously energizing C10 to determine the right turn time.
10:59The scheduled time has elapsed.
11:00The timed contact of C10.
11:0367 to 68.
11:04Energize coil C11.
11:07That is self-supporting for 13 to 14.
11:09When C11 is energized.
11:11The circuit of C1 and C10 is opened.
11:13Through contact 31 to 32 of C11.
11:16The engine stopped during.
11:19The time scheduled by C11.
11:22The predetermined time has elapsed.
11:24The timed contact of C11.
11:2667 to 68.
11:27Close the circuit of coil C2.
11:30That is self-supporting for 13 to 14.
11:32Starting the engine to the left.
11:34At the same time as the C11 coil is de-energized.
11:37Through contact 61 to 62 of C2.
11:52Everything is fine.
