PROBLEM TO BE SOLVED: To provide a motor drive unit including an inverter unit capable of solving a problem that a DC voltage of a rated voltage or the like is applied to a connector or a connecting unit due to a connection failure, a human error or a machine error at the power supply resulting in a failure of the inverter unit.SOLUTION: A DC power is connected not only to positive and negative input terminals of the inverter unit via a connection unit but also to a capacitor unit to supply an output voltage from the DC power. The motor drive unit includes an inverter unit, the output terminal of which is connected to an inductance load. The capacitor unit includes plural capacitors connected in series. |
