PROBLEM TO BE SOLVED: To provide a motor driving apparatus which in either of cases where the motor driving apparatus includes only one motor driving unit and the motor driving apparatus includes a plurality of motor driving units, is allowed to be downsized.SOLUTION: In a motor driving apparatus 1 including at least one motor driving unit 2, the motor driving unit 2 includes a drive circuit substrate on which a drive circuit and a control circuit of a motor are mounted and a frame 4 on which the drive circuit substrate is fixed. A power supply circuit substrate on which a power supply circuit for supplying power to the drive circuit substrate is to be mounted and a cover member 7 for covering the power supply circuit substrate can be attached to the X2 direction side of the frame 4, and in a state where the power supply circuit substrate and the cover member 7 are detached from the frame 4 of a motor driving unit 2B, an X2 direction end of the frame 4 of the motor driving unit 2B can be brought into contact with an X1 direction end of the frame 4 of a motor driving unit 2A. |
