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.

Abstract: In a unitary bifurcated brush holder for a small electric motor, a pair of coplanar terminal tabs, each axially spaced and laterally offset from the brush holder sleeve, extend axially of the motor for direct plug-in engagement, in assembly operation, with terminals at the commutator end of a stator assembly. The brush holder is made from a single sheet metal stamping. The terminal tabs are carried at the end of a support arm extending from a wall of the brush holder sleeve. In assembly, the brush holder is mounted in an insulator which includes support bosses for engaging and augmenting the support of the rear end of the terminal tabs.

Abstract: In a stator provided with interpoles, a magnetic flux adjusting winding is provided adjacent to the radially inner end of each interpole core for adjusting the magnetic flux passing through the half of the circumferential width of the interpole core, so that the intensity of the magnetic flux passing through the radially inner end of the interpole core becomes substantially uniform along the end face of the interpole core, whereby the waveform of the commutating emf is simulated to that of the reactance voltage to widen the width of the no-spark zone during commutation thereby improving the commutation performance without appreciably modifying the original shape or structure of the stator.
