U-113 APPLICATION NOTEDESIGN Notes ON Precision Phase Locked SPEEDCONTROL FOR DC MOTORSABSTRACTT here are a number of high volume applications for DCmotors that require Precision control of the motor s Locked loop techniques are well suited to providethis control by Phase locking the motor to a stable andaccurate reference frequency. In this paper, the small sig-nal characteristics, and several large signal effects, ofthese loops are considered. Models are given for the loopwith Design equations for determining loop bandwidth andstability. Both voltage and current motor drive schemesare addressed. The Design of a loop for a three phasebrushless motor is LOCKING GIVES Precision SPEEDCONTROLThe precise control of motor Speed is a critical function intoday s disc drives.
