What is forward/reverse starter?
The Reversing Starter is a special type of push button starter wherein addition to starting/ stopping of motors the director of rotation of a three phase induction motor can be done by inter changing the connection of any two terminals of the supplies which is done through two separate contactors, one for forward and ...

Where is star delta starter used?
In a (squirrel) cage induction motor, the starter is used only to decrease the input voltage to the motor so as to decrease the starting current. It is T.P.D.T switch used to first start the motor with the winding connected in star and then switch for delta connection in running position.

How does a star delta starter work?
During starting the motor windings are connected in star configuration and this reduces the voltage across each winding 3. This also reduces the torque by a factor of three. ... The Star/Delta starter is manufactured from three contactors, a timer and a thermal overload.

Hi, thanks for sharing this video.
I think, power cable for Reverse, those two phase cable "RED AND YELLOW" should be exchanged at R main contactor input end, rather than output end. otherwise, when take reverse action, delta side, cables cannot be exchanged. it will bring short cuit risk.

YOUR YELLOW PHASE IS CONNECTED TO SAME WINDING U1 U2 PLS CLEAR UR VIDEO

In this connection, coil u1 and u2 get yellow phase when reverse contactor energise. For resolving the issue need to make phase change(R and Y) on reverse contactor input side instead of output side.

I’m a residential electrician and would love to learn motor controls. Do you have something available for a beginner and a place I could order parts from?

Sir, i think this drowning rong. Because, u1+u2 v1+w2 w1+v2. This good u1+v2 v1+w2 w1+u2 or u1+w2 v1+u2 w1+v2 .

No need for two overload relays, the load for U1 V1 and W1 will be the same as the current in U2, V2 and W2 unless in case of a short circuit, and in that case the circuitbreaker is the protection.

Hello bro, Can you tell me which software you use in this video?

Delta contactor incoming connection is wrong, just swipe L1 to L2 in Delta contactor incoming side contacts. Else u will get R-phase at U1 and Y-phase at W2, this may burn motor. No matter in what direction u are running motor, motor terminal should have(U1W2- R-phase, V1U2-Y-phase, W1V2-Bphase), for other direction motor terminal should have(U1W2- Y-phase, V1U2-R-phase, W1V2-Bphase), hope u understood. Other connection is ok

My friend your diagram is very well
I need this diagram with nc no switch can you help me

This circuit is wrong. Phase reversal should be taken before reverse contractor so that in reverse condition, both side of winding will get phase reversed. In this circuit, Yellow phase will be connected to both end of U winding and winding V and W are in parallel with phase R and B connected across. Please correct the drawing. Thanks.
