Abstract
A rotor is fabricated of a plurality of strips of thin amorphous metal wound side by side into adjacent coils about an axis, the flat sides of the strips being parallel to the axis. The rotor material is annealed to increase its coercive force to a value which may be up to 100 oersteds, rendering the rotor useful in a hysteresis type motor.
