UNIVERSAL MOTOR WITH SECONDARY WINDING

In a two pole universal motor (10) for a circular saw a secondary winding (78, 80) provides dynamic braking. Both run and brake windings (66, 68, 78, 80) are split electrically with respect to the armature (22). All windings are double-ended. All windings may be terminated directly to fixed end poin...

Summary:In a two pole universal motor (10) for a circular saw a secondary winding (78, 80) provides dynamic braking. Both run and brake windings (66, 68, 78, 80) are split electrically with respect to the armature (22). All windings are double-ended. All windings may be terminated directly to fixed end points (70, 72, 74, 76, 82, 84, 86, 88), four at each end of the stator (44), providing for axially oriented plug-in connection of brushes (50, 52) at one end (34) and switch (90) and line (64) at the fan end (38). There are no jumpers within the stator (44).
