To reduce a user frustration due to a deterioration or a noise generation of a machine due to vibration suppression and vibration while driving a motor.
A motor driving apparatus 100 includes: a motor 3 driving a load; an inverter 2 applying an electric voltage; an inverter controller 4 controlling the electric voltage outputted by the inverter 2; a vibration detector 5 mounted on a predetermined position in the motor 3 and detecting a vibration of the motor 3; vibration output corrector 27 correcting an output from the vibration detector 5; a vibration separator 6 separating vibration components in a tangential direction from the output of the vibration output corrector 27 to a rotation axis of the motor 3; a vibration suppression controller 7 outputting a signal for suppressing a vibration based on the output of the vibration separator 6. The inverter controller 4 controls the electric voltage which is applied at the inverter 2 based on the output of the vibration suppression controller 7.
