Abstract

Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A bevel or spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly, a driver and a one-way clutch or ratchet bearing assembly may be used to form a cam controlled speed converter converting a given input to a variable or constant output speeds and further having direction control. All IVMC's, cam controlled IVMC, input compensated IVMC and pitch controlled IVMC may be utilized to form various embodiments of infinitely variable generators, transmissions and compressors/pumps.
