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.
Claims6
A hysteresis machine comprising:
- a stator structure having a central opening and having a central axis and stator winding means for producing a rotating magnetic field which rotates about said central axis;
- and a rotor structure positioned within said central opening in said stator structure and within said rotating magnetic field and being rotatable relative to said stator structure about said central axis, said rotor structure comprising a plurality of adjacent coils of amorphous metal tape wound substantially concentrically about said axis so as to collectively define a rotating magnetic body having the hysteretic properties of a hysteresis machine rotor, each coil comprised of a plurality of turns of tape and each tape having its flat sides parallel to the rotor axis.
