The semi-cross interlocked circuit with unbalanced voltage cyclic current check function for the speed difference permitted commutator type motors

摘要

At least two commutator type motors are arranged to reduce cyclic voltage imbalances or oscillations by connecting a check diode in series with the armature of each motor, and by partially interlocking the motors by connecting the series winding of a neighboring motor to the end of the armature which is not connected to the check diode. <IMAGE>
