Define frequent. I maintain machinery with brushes so I have a decent idea of what life span should be depending on the environment. If the housing for the slip ring setup is well protected from dirt and the slip rings aren't cleaned by a cave man you can get a few years of life from the brushes.
- chipsa 4mo agoIf the desired location for this is a car, then a few years of life that requires half disassembly of a motor isn’t going to work.
- w4der 4mo agoThat does not sound worse than replacing the spark plugs in a Subaru engine.
- coryrc 4mo agoThe slip rings are not in the middle of the motor, they're on the butt. I know car makers don't always try to make things serviceable, but it'll be hard to make it hard to replace. Probably the only issue will be needing to remove other parts first to get to it, if anything.
- MisterTea 4mo agoThey do not need to be half disassembled. That's hyperbole. Brushes are usually easily assessable from a cover at one end of the motor or dedicated brush holders accessable from the outside.
