Abstract
A long-life motor brush holder which significantly minimizes contact of the coil portions of a ribbon spring with the holder and consequently reduces friction drag; the arrangement is such that at least two cylindrical surfaces forming part of the brush holder serve as line contact supports for each of the respective coil portions of the ribbon spring so as to produce minimal contact, the spring including a middle portion for residually engaging the brush to urge it against the motor commutator.
