Simultaneously operative multi-unit AC or DC series excitation motors or compound motors interlock driving circuit device.

摘要

An electric motor assembly comprises a number of motor armatures (Aa, Ab) each in series with a field winding acting on the next armature in sequence. Diode (CRn) and/or resistors (Ro) may be incorporated to suppress circulatory currents. Shunt field windings may be provided, and also switching means for speed control. <IMAGE>
