The operation accuracy of a printing unit is improved in a printing apparatus. To accomplish this, a motor driving apparatus comprise a brushless motor including coils of a plurality of phases, and a plurality of detection units that output voltages in accordance with rotation of a rotor, a driving unit that drives the brushless motor by switching a current supply destination between the coils of the plurality of phases based on a control signal, and a generation unit that generates the control signal based on addition results of detection signals output from the plurality of detection units, and correction signals based on differences between a predetermined voltage corresponding to a rotation angle of the rotor and voltages corresponding to the rotation angle of the rotor that are obtained from the plurality of detection units.
