Appeal No. 1998-2947
Application No. 08/682,876
The invention is directed to a roller-type motor wherein the moving part, or
motor of the motor rolls on the inside of the stator such that the motion is like a
barrel rolling inside of another barrel. The motor is used in high-torque, low
revolutions applications.
Independent claim 1 is reproduced as follows:
1. A roller-type electric motor, comprising:
a housing having a hollow interior and an inner wall;
a plurality of stator poles each of predetermined electrical polarity and
positioned at said inner wall of said housing;
a roller having an outer surface and positioned for rolling movement
within said hollow interior of said housing,
a plurality of roller poles each of predetermined magnetic polarity and
positioned on said outer surface of said roller, a first one of said roller
poles having a magnetic polarity opposite the magnetic polarity of a first
one of said stator poles so that said first roller pole is drawn through
magnetic action into contact with said first stator pole; and
control means for reversing the magnetic polarity of said first stator pol
