Abstract
In a 2 pole universal motor for a circular saw a secondary winding provides dynamic braking. Both run and brake windings are split electrically with respect to the armature. All windings are double-ended and wiring and winding is arranged so that all windings may be terminated directly to fixed termination points, four at each end of the stator, providing for axially oriented plug-in connection of brushes at the commutator end and switch and line at the fan end. There are no jumpers within the stator.
