PROBLEM TO BE SOLVED: To provide a work vehicle which is capable of performing feedback control with high accuracy on the basis of rotation angles and current values of motors even in the case where one A/D converter is shared by a plurality of motors.SOLUTION: A driven part is driven by the plurality of motors. A power conversion circuit that is disposed correspondingly to each of the motors supplies a drive current to the corresponding motor. A current sensor measures the drive current supplied to the motor. A rotation angle detection device that is disposed correspondingly to each of the plurality of motors measures the rotation angle of the corresponding motor. An A/D converter successively performs A/D conversion on the current values measured by a plurality of current sensors. On the basis of the current values outputted from the A/D converter and the rotation angles measured by the rotation angle detection devices, a control part controls the power conversion circuits. The rotation angle detection device is controlled for each motor in such a manner that acquisition timing of the rotation angle by the rotation angle detection device is matched with acquisition timing of the current value on which the A/D conversion is performed by the A/D converter.SELECTED DRAWING: Figure 1 |
