Abstract

The motor drive unit (100) for controlling the motor includes: a circuit board (4) for mounting the control circuit of the motor; a frame (3) for fixing the circuit board (4); and a housing (2) fixed to the frame (3) and housing the circuit board (4). The circuit board (4) includes: a main board (41) extending in the Z direction; a sub-board (42) fixed to the main board (41) and extending in the X direction and having a display portion (6) exposed from the display hole portion (210) of the front surface panel (21) in the Z1 direction of the housing (2); and a USB terminal (51) mounted in the Z1 direction of the main board (41) and exposed from the front surface panel (21). When viewed from the Z1 direction, the USB terminal (51) is located between the upper end (421) and the lower end (422) of the sub-board (42) and is located further in the Z1 direction than the sub-board (42).
