PURPOSE: To overcome faults of the nonuniformity of drive characteristic at the time of the parallel operation of a commutator type motor of a plurality of serial field coils or a shunt field or the commutator-type motor by a permanent-magnet type magnetic field. CONSTITUTION: In two pairs more of series motor assemblies or compound motor assemblies excited by serial coils, each pair of armature coils A101, A201... are mutually connected in parallel, and connected in series with each pair of serial coils S101, S201. |
