An electrically powered suspension system 11 achieves vibration control of a vehicle without disturbing a vehicle behavior and impairing riding comfort even if an electric motor 31 of an electromagnetic actuator 13 generates excessive heat, wherein the electromagnetic actuator 13 includes the electric motor 31 generating a driving force for vibration damping and extension/contraction; a target damping force setting part 51 setting a target damping force; a target extension/contraction setting part 53 setting a target extension/contraction force; and a drive controller 49 performing the drive control of the electric motor 31 using a drive force based on the target damping force and target extension/contraction force by limiting the motor current not to exceed a current threshold that is an addition of a damping current threshold and extension/contraction current threshold, which thresholds are separately configured considering a priority of riding comfort and steering stability.
