a well thought out explaination

The auxiliary coil M

Greetings to you sir. Great tutorial. Can you do two of this circuit in one so that when one motor stops, the other starts? 3 phase.

Very informative. I’m a woodworking guy, and a novice in electrical automation. I am trying to automate my shop vac filter cleaning. I have a 2kw 220V shop vac, and a small 200W motor that runs the filter cleaner. I start and stop the shop vac with a remote controller. Today I run the shop vac filter cleaner manually. I would want to run it automatically with a time delay, such that it starts 5 sec after shut down of shop vac, and runs for 10-15 sec, and then shuts down. This repeats after each time I use the shop vac. Do I need a full set of interlocking contactors, relay and timers to ackomplish my goal? Can you guide me, or better still, could I ask you to create a KZfaq video on this topic, as I am sure I am not the only one struggling with this task.

Hello Thanks for the video. Can you help me on the following:

if i remove the contact M and keep the timer will the timer still count 5 seconds if i press for 1 sec i will be left with 4 seconds or will it restart waiting for a continuous 5 seconds

Dont you need a cr1 to hold the start in place? Or does the time relay hold the botton closed?

You are technical but not clear may be you should have a better video
