I have a 1 HP single phase 115 volt motor. The start-up points are burned out and I can't find replacement points for this motor. I would like to repair it using an external relay to replace the start-up points. I was told that I can do this by using a timer to control how long the relay will remain closed. I plan on using a 555 timer circuit to control the delay on the relay.
My question is how do I decide how long to have the relay delay before opening?
The motor will be used to power a small metal lathe.
Thank you.
