摘要
At least two components that use DC power to drive at least two motors, such as DC armatures, field windings, etc., collectively referred to as DC driving devices, are connected together by switching components which can be operated to selectively connect the driving devices either in parallel or series or, in the case of more than two DC driving components, in mixed parallel and series configurations. The switching components can be solid state or electromagnetic switching components, including components that have variable resistances so as to allow continuously variable control of the series/parallel connections between the elements, and can be switched by modulation of control or trigger pulses. When the DC power driving devices are in the form of DC armatures, the series and/or parallel connection effects can also be further modulated by shunt field control of the armature currents.
