PROBLEM TO BE SOLVED: To provide the control device of a motor which can be miniaturized.SOLUTION: A control device (10) of a motor includes: a motor (1) having a stator (41) constituted by winding coils (44) around a plurality of teeth (43) projecting from a back yoke (42); a converter (20) for stepping up or stepping down a DC power; and a power conversion apparatus (30) for converting the output of the converter (20) into an AC power. The control device (10) is configured to drive the motor (1) by supplying a power from the power conversion apparatus (30) to the coils (44). The converter (20) includes a transformer (65), and a part of the back yoke (42) is used as the iron core of the transformer. |
