Patent ID: 7034490

Claim:
A motor positioning servo loop comprising: a microcontroller device; a digital to analog converter, having a digital input and an analog output, said digital input receiving digital signal from said microcontroller device and said analog output coupled to a motor actuator; a motor coupled to said motor actuator; a detecting device, having a digital output, said digital output coupled to said microcontroller; wherein said detecting device detects a physical parameter comprising at least one member of the group consisting of position, velocity and acceleration; wherein said motor actuator receives an analog signal from said digital to analog converter and delivers electrical energy to said motor; wherein said digital to analog converter is an oversampling digital to analog converter, comprising a digital oversampling modulator, whose output signal is a bitstream analog signal, and whereby said microcontroller receives a commanding digital signal from a commanding source and a feedback digital signal from said digital output of said digital output of said detecting device and processes the digital data to drive said motor actuator in response to said commanding digital signal and said feedback digital signal to control said physical parameter.
