ABSTRACT:
An induction motor with an improved torque/slip characteristic has a solid rotor having longitudinal grooves running parallel to the axis of rotation which connect with circumferential grooves at each end of the rotor. The rotor is plated with copper so that the grooves are filled with copper. The rotor is then machined over the cylindrical outer surface to produce a solid, non-laminated rotor having high-conductivity paths in the longitudinal grooves connected by high-conductivity short-circuiting rings in the circumferential grooves.
In a modification the longitudinal grooves may be skewed. Other high conductivity material may replace copper, for example aluminium.
