Abstract

See full text

A controller of a motor control device increases a voltage to be applied to a coil based on a control signal calculated from an estimated rotation speed, when the estimated rotation speed becomes equal to or lower than a predetermined rotation speed, increases the voltage to be applied to the coil based on a control signal calculated from an actual rotation speed, in a case where the actual rotation speed is lower than the predetermined rotation speed when the estimated rotation speed becomes higher than the predetermined rotation speed, and decreases the voltage to be applied to the coil based on a control signal calculated from the actual rotation speed, in a case where the actual rotation speed is higher than the predetermined rotation speed when the estimated rotation speed becomes higher than the predetermined rotation speed.
