Motor drive device

Abstract

Provided is a motor drive device capable of achieving a desired circuit configuration despite having a small number of types of bus bars. The motor drive device has a bus bar assembly including a first bus bar and a second bus bar, and a coupling means for coupling the first bus bar and the second bus bar to each other. The first bus bar, the second bus bar, and the coupling means are configured such that the bus bar assembly has a plurality of shapes that differ in position and / or posture of the second bus bar with respect to the first bus bar.
