    摘要： A d.c. motor having large, semicylindrical, chamfered pole pieces of soft magnetic material for focusing the magnetic flux of two permanent magnets onto the armature of the motor to provide an increased flux density. the armature has skewed slots and the edges of the pole pieces are skewed in opposition to the skewed slots to achieve the effect of a complete slot pitch skew in a short armature stack without having the loss of wire space normally associated with the severe skew angle previously utilized. The motor is mounted in an improved housing that has a removable brush cap attached to a retaining ring which is rotatable within a slot in the housing transverse to the axis of armature rotation to permit rotary adjustment of the brush cap.
