Infinitely variable motion control (IVMC) for river turbines
Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A 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 and a driver may be used to form a speed converter. The speed converter is used in various forms to provide an infinitely variable transmission, a differential, embodiments of wind and river turbines and pumps/compressors. In one embodiment, the speed converter drives first and second directional control assemblies to provide a vehicle with zero turn radius. A variable torque converter may be used in various embodiments to control torque from a minimum to a maximum by controlling movement of a rotor along a shaft in relation to a stator.
