Direct Drive Brush Frameless Torque Motors

dc-cube-motor-grey-background_700x400-block.psd

Moog's brush frameless torque motors feature double insulated high temperature magnet wire to minimize leakage current and promote superior insulation. Our molded brush block assembly has interchangeable brush blocks, optimizing brush position on the commutator. Brush contour is done on automatic tooling rather than 'run in' individually. Brushes are mechanically fastened to the brush spring in addition to soldering to assure top brush alignment during soldering operation plus establish a fine mechanical and electrical bond between spring and brush. These motors feature large axial holes through armature for easy application to shafts and bosses. Stable high-temp material minimizes movement or working of windings under large temperature variation. This high-temp material will not crack under temperature variations, and eliminates voids, exposed windings and humidity traps.
