We are designing a part of a machine that has a motor that has to be switched on/off and forward/backward rather frequently.
Initially we started with eletromechanical relay (EMR) but we had many motors spoilt in the course of running. So now, some of us are suggesting to use solid-state relay (SSR) in place of this EMR.
My question is, can somebody explain theoretically can/how SSR actually helps prolong the lifetime of the motor.
No doubt, the SSR is better in this case because it is not susceptible to arcing and mechanical wear during switching, but this only helps prolong the relay's lifetime.
Hint: Is it something to do with the zero-switching characteristic of all SSR?
Thank you for your help.
