Abstract

A motor control circuit for a motor is provided. The motor control circuit drives the motor based on torque command data. The torque command data is output by adding speed error data output from a speed error detecting section based on a first reference clock and a speed pulse and phase error data output from a phase error detecting section based on a second reference clock and the speed pulse. Each of the speed error data and the phase error data is output within a detection range set by a setting section provided for each of the speed error detecting section and the phase error detecting section.
