I have a 12 VDC motor, 0.9 horsepower, that I need to cycle frequently in both directions. The motor (a winch motor) is being underutilized for what I am doing with it. The duty cycle looks like this: It is biased in one direction for about 2 seconds with about a 40 amp steady-state draw (but a substantial in-rush I am sure), then rests for about 15-30 seconds, then it is biased in the other direction for about 2 seconds with about half as much draw, but probably the same(?) in-rush and then it rests again for 15-30 seconds.
I am failing the mechanical relay contacts in this application, I am guessing because of the frequent arcing on the break of the contacts. Can anyone recommend a solution for absorbing the flyback in both directions? Thanks in advance.
