A digitally controlled motor device with storage (1) comprises a stator and a flywheel (10) having an axis of rotation and being rotatably mountable on a shaft (60) of a rotating machine and having at least a first set of magnetic coils (13) arranged thereon; an induction rotor (20) having an axis of rotation and being mountable on the shaft in magnetic communication with the first set of magnetic coils of the flywheel such that a change in magnetic flux at the first set of magnetic coils induces a current in the induction rotor. At least one set of second magnetic coils (12) is arranged on the stator in magnetic communication with the induction rotor (20). A controller (30) controls a supply of electrical power from the flywheel (10) to the second set of magnetic coils (12) to force acceleration or deceleration of the induction rotor (20), whereby the induction rotor (20) is adapted to receive electrical power from the flywheel (10) via the first set of magnetic coils (13) and from the second set of magnetic coils (12).
