Abstract
An infinitely variable transmission includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback control is provided. The input assembly is coupled to receive input rotational motion. The output assembly provides a rotational output. The output assembly is configured to be rotationally coupled to a load. The input/output planetary ratio assembly sets an input to output speed ratio. The input/output ratio assembly includes a first and a second stator. The torque feedback control assembly provides torque feedback to the input/output planetary ratio assembly to at least in part control the input to output speed ratio of the input/output planetary ratio assembly. The torque feedback control assembly includes a phase relation system operationally coupled to the first and second stator and a torque system operationally coupled to the output assembly. The phase relation system further is in operational communication with the torque system.
