ABSTRACT:
An apparatus is provided for use with a motor drive for cancelling the electromagnetic reaction energies developed by a pair of drive motors upon rapid starting or sudden stopping, the latter occurring upon the application of dynamic braking to said motor drive. The apparatus comprises a pair of motors each provided with rotors preferably having moments of inertia which are substantially equal. The output shafts of the motors are operatively connected so as to rotate in opposing directions.
