PROBLEM TO BE SOLVED: To provide a motor controller which controls a high voltage motor without requiring a high-voltage battery, improves the maintenence ability because the safety for battery exchange becomes high, and enable reduction in size and weight simultaneously with energy saving. SOLUTION: The motor control comprises the battery 1 for generating the prescribed DC voltage, a bidirectional type voltage setup chopper unit 2 for setting up a DC voltage generates from the battery 1 to obtain an inverter 4 for driving a motor 6, based on the setup voltage, and an electrolytic capacitor 3 that is connected between the bidirectional type voltage setup chopper unit 2 and the power supply for driving the motor 6, in order to smooth a DC voltage of the bidrectional type voltage setup chopper unit 2. |
