In an SCR circuit controlled universal motor, means for providing smooth speed control at all speed settings comprising,
- a series wound stator field in said motor, and
- at least one closed conductor loop of wire encircling the stator magnetic flux path.
The method of providing smooth speed control at all speed settings of an SCR circuit controlled universal motor comprising,
- winding at least one metallic conductor wire around the stator magnetic flux path, and
- securing the wire ends together to form a closed loop.
The method of providing smooth speed control at all speed settings of an SCR circuit controlled universal motor comprising,
- winding at least one copper wire conductor of 10 gauge or greater around the stator magnetic flux path, and
- securing the ends of said wire together to form a closed loop.
