ABSTRACT:
An encoder in a motor system measures radial movement and translational movement of a disk with a single integrated sensor disposed on a microprocessor chip. The encoder measures position information and eccentric movement of the disk by the integrated sensor. The measured positional information and eccentric movement information are then combined generating single corrected positional information of the disk. The corrected single positional information may be provided to a user in standard format for operation of the motor system.
