Abstract
A motor drive controller is provided with: a motor drive circuit that drives a motor and having a position detector that detects a position of a rotor of the motor and outputs a position detection signal; a motor control circuit that generates a rotation pulse signal based on the position detection signal output by the motor drive circuit; and a microcomputer that is provided with at least one timer and outputs a conversion signal that is obtained by multiplying the rotation pulse signal by n, where n is a natural number equal to or greater than two.
