Abstract
An electric motor has a casing having two opposed planar side walls and two opposed curved walls. A permanent magnet is located inside each curved wall and a wound armature is mounted in the casing. A commutator is connected to the winding and two brush arms are supported by a holder at one end of the casing. Each brush arm informed by two electrically conductive strips forming, respectively, a terminal part and a more resilient brush supporting part. The terminal parts extend out of one end of the casing in a plane of symmetry of the casing thereof and the brush supporting parts are secured to respective terminal parts at positions which are offset from the plane of symmetry, on opposite sides thereof.
