摘要

Improvements introduced in the object of the main patent no. 334,432, requested on december 12, 1966, by "a device driven by electric motor powered at discretion by different input voltages", characterized in that the motor has a stator and a rotor, the stator is provided with field poles to generate a magnetic field, the rotor includes a central axis, a plurality of armature plates mounted on the shaft and has grooves extending substantially axially at its outer periphery, the manifolds are mounted on the shaft, and the windings are both wound on the slots of the armature, and further comprising means including a first set of brushes for applying low voltage to the first collector when battery operation is desired, means including a second set of brushes for applying high voltage to the second collector when desired operation with the network, and interlocking means to prevent the application of a voltage to one of the dur collectors before the application of the other supply voltage to the appropriate collector.
