Automatic induction motor starter (solid state)


Thread Starter

narender reddy

i want to design an automatic induction motor starter for single phase (student educational project), which wil switch on the motor as soon as power is back after power cut. But it should have protection against starting current and overload, etc. how can i do this with least hardware and cost for an single phase induction motor of 1HP, 230volts or a fan motor etc.?

Whenever there is a power outage the motor starter is switched off and when the power is available back. the motor does not start but it should be manually started again. I want to do it automatically and it should also reduce the heavy starting current.

Any help in the form of circuits, Links and tutorials will be appreciated. I am in very need of it.
