Can we use the micro metal HIGH power carbon brush(6Volt) for biomedical products, provided we use only about 25% of the stall current?( Pololu item #: 3066 ) What will be its life cycle?

I was wondering if I can use the micro metal gear-motor(HPCB 6Volt) in one of my industrial project provided i keep the motor current equal to 25% of motor’s stall current. How much life expectancy I can expect?


Unfortunately, we do not have our motor or gearbox lifetimes well characterized, and in general, the lifetimes can depend on many different factors. What kind of lifetime are you looking for? Can you tell me more about the conditions (like if its going to be operating continuously or what the on versus off time is)?

Thank you for your reply Patrick.

It will not be operated continuously. We are thinking of using it in our prosthetic hand for our thumb motion. And as such you will notice that amputees use their prosthetic hands only for about 20-30 mins continuously at maximum.

What kind of cumulative operating lifetime are you looking for?
