An apparatus is provided for use with a motor drive for cancelling a reaction energy of a drive motor upon rapid starting or sudden stop. The apparatus comprises a revolving member adapted to be operatively connected with the rotor of the drive motor. The member has an inertia which is equal to that of the rotor, and is adapted to be connected with the latter in the opposite sense therefrom.
