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 is provided with an oil pump that supplies oil to a stepless transmission device, a brushless motor that drives the oil pump, and a control device that controls the brushless motor. The control device is provided with a power supply part that supplies drive power to the brushless motor, and an out-of-synch determination part that determines whether or not the brushless motor is out of synch. The control device is provided with a drive control part that controls the power supply part so that supply of power to the brushless motor is stopped, and then controls the power supply part so that the brushless motor is started, when the out-of-synch determination part determines that the brushless motor is out of synch.
