摘要

The device has a cylindrical housing (2) closed at the ends by end covers (5), an armature winding and commutation elements in the form of a rotor carrying a collector. One end cover has an inward protrusion carrying two bearing bushes for the rotor shaft (3) and the other end cover carries at least two commutator brushes (9,10).
