<p>Provided is an electric pump device that can continue to supply hydraulic pressure to hydraulically actuated equipment and that is also of reduced size. An electric pump device (P) is provided with an oil pump (5) that supplies oil to a stepless transmission device, a brushless motor (6) that drives the oil pump (5), and a control device (7) that controls the brushless motor (6). The control device (7) is provided with a power supply part (71) that supplies drive power to the brushless motor (6), and an out-of-synch determination part (73) that determines whether or not the brushless motor (6) is out of synch. The control device (7) is provided with a drive control part (72) that controls the power supply part (71) so that supply of power to the brushless motor (6) is stopped, and then controls the power supply part (71) so that the brushless motor (6) is started, when the out-of-synch determination part (73) determines that the brushless motor (6) is out of synch.</p> |
