Hello young people, Professor REYNER greets you, we continue with the simulator classes of
each tenth today we are going to do an exercise with the first motor and well we are going to
read the statement says here elaborate the command and force scheme of the simple start of a single-phase
motor so today we are going to make the simple starting of a single-phase motor taking
into account the following the following working parameters the first point says that we are going to press
start and the motor is going to start we are going to press stop in the second point we are going to press stop and the
engine is going to stop we place the necessary signals here when we already come to a simple start it
means that the engine must already have its control scheme where we are going to
locate everything that is with it In this case, the command is turned off, the emergency
stop, the auto interlock, they already know everything that is an electrical retention or in memory
that they also call it and well, the third point can being here it says that we are going to locate the signal
then we are going to signal when the engine system is stopped we are going to signal when the
engine is running and we are going to signal when the engine has a fault well now we will go
to the software to carry out the assembly of the elements well here we are already we are in our
workspace and we are going to start with our strength scheme today I am going to do it like this
so that in the next one, you can do it for yourself then we look for our food system
We locate it here now we are going to look for our circuit breaker that has escaped me right
now I do not know where it is we are going to find it here we are going to look for a double one because it is a
single-phase motor and we are going to use this one that is here then we bring it to our space work
now we are going to look for this the auxiliary contact where the auxiliary contacts are here are
the auxiliary contacts or switches of the contacts we are going to look for a contacts double because it
is a single phase motor and now we are going to look for our protection or motor guard we
look for it where they are I lost I remembered it has been lost here it is here and since we have
a good single phase motor right now the software offers us the possibility of using
only this one that has three we are going to use it in this way because it is the only one there and now
we are going to look for we already have our motor bar our thermal relay now we are going to look for the
single-phase motor that people who are here have our single-phase motor here we are going to put now what we are
going to do this is to make the respective connections we are going to connect here the output
of the director to the input of the auxiliary contact now the output of one goes with one
the output of m is 4 It goes with the 3 now the motor we are going to connect the 2 with 1 and here we are
going to bring it to voltage 1 now these issues are with this contact here we leave it free now
we are going to look for our connection from the polarity to ground then we are going to lead here
and it passes here and we leave it connected here and then now we are going to put it here then the circuit breaker
1 here this is I do not like the script very much so I delete it from the beginning of the auxiliary contacts
of him here m 1 which is motor 1 well now we are only right now we are only
occupying a motor there is no problem this is our thermal relay so we are going to place it like
this in this way here we already have this is our motor 1 We are going to take the scheme
in order to all the ones that this is m 1 so here we have everything that is this we are going to say forcefully true
then we are going to leave it a little more here now we are going to do this the command we are going to look for our
food is and We are going to put our first feed here, which is we are going to put Steele 1 here
and we are going to put the neutral further down here we are going to turn it so that it is not seen and
we turn it all, nothing happens now, what follows is to search the contact To the auxiliary of the
thermal relay that at the moment I do not have them where they are I think that if these are here we have and
since we are going to use these two signals, I can use this contact, this thermal or
this thermal, then I will leave using this thermal this is here I am going to eliminate it
and now we are going to put our emergency stop as we do not have a fungus I use a
normally closed switch so I do it and now we are going to put our ignition on and stop green then I
turned on this the first thing is stop around here we are going to stop running and now
we are going to bring the normally closed one which is the stoppage, here we have it now we are looking for our
coil km / 1 we are going to use a normal coil is this one here here m 1 if we have it here
and this now we are going to use an auxiliary of each m 1 for this car to nail it in parallel
to the ignition and well now continue this we are going to use a normally closed contact that
we are going to use to turn off the l A lamp and a lamp a signaling so now that
we need the signals we are going to finish locating this a signaling
on a signaling off we are going to put it here and a signaling we are going to put
flashing but it can be from the same lamp Actually this is the signal that will indicate when
the motor has some kind of fault and we will leave it that way then now we are going to make the
connections we are going to see here we connect all these elements are connected in series
and we are going to connect up to here this situation the lamps I feel that they are already where they should
be then I am going to interconnect them to the neutral line then here we are going to put
ours until here it comes later I am going to move this contact and we come to attack we are going to move this
contact to leave it aligned in parallel to the signal that indicates that
this contact is operating, which is here, will indicate the stop of the system lamp on and This case when it
is lit in color we are going to say like this in red then here we are going to send it to
connect up to here and lastly we are going to leave connected the lamp that indicates the failure of the
system when it has a failure now we are going to put the names this It belongs to the f1 thermal relay
, so you have to put the correct name, I remind you that if they do not have the same names
, they will not act correctly this is an emergency this here is this we are
going to put it off we are going to start using these two terms that is off this is going to
be turned on we are going to put it as this is the coil of each one then here m 1 this is an
auxiliary of each one that we are going to use for the car in the retention or auto interlocking of the
system this is the one that indicates this ignition, therefore it will be h 1 and from the green color it
indicates that the system is off it will be h 2 and this will be red this here
indicates this will be h 3 and this is the lamp i ntermittent that will give an alarm of this
failure of some kind of failure coughs here this will also be a closed auxiliary of each m 1
and here we already have the whole system here we already have the whole system we will see in the
signaling alarm it is in this alarm we can use one of these sirens or buzzer or buzzer
then let's see let's see we have everything armed now let's see the simulation then
when we come to simulate we close the circuit breaker then we have our power scheme
here and here we have our control when we come in control we start at the
red lamp indicates that the system is stopped when we press on the coil km / 1 is going to be analyzed
here m1 is going to send its contacts to activate the first contact that we are going to
explain is that of the auto retention and the second contact will be that of the ignition lamp
then these lamps will be red it will turn off and it is green it will turn on all of
that instantly It is going to send its auxiliaries to activate its main contacts, sorry,
these are the utility of the main one and when that happens because the engine is going to start and the car in
each interlocking is going to send to hold here and it turns out that the engine is going to be
The engine is going to be on and the engine is on, we can press stop, they exchange the lamps again and
the engine turns off when we simulate a failure in the thermal relay, a high temperature, let's see
that the system turns off, the red lamp and the Mary lamp are turned on. It will be intermittent
then we are going to cover the whole system. We turn on here as we can see everything happened.
All the contacts of each one turned
on. The circuit is closed
, the lamp was turned off, and this contact, which is open, the main contact, was
logically closed, that energy flowed and in that way, the motor was switched off.
It turned on now we are going to do the opposite we turn off and the whole system is turned off that way this is how this
simple diagram works now if I have it turned on and we come to simulate a preheating we simulate
heating here then the color the lamp allows t it should turn on indicating that
there is a failure in the system in this way is how this whole diagram works then this one
we must press again we are not going to restart the system here we must restart
the system deactivate this alarm and come here we are already explaining I say goodbye to
