ABSTRACT:
This invention is for incrementally controlling energizing and de-energizing of at least two electrical motors in which motor armatures are mechanically coupled to a single mechanical member and in which motor stators are mechanically referenced to a second mechanical member. By energizing and deenergizing two or more electric motors of different force and torque capability coupled in this manner it is possible to provide increments of force and torque as small as the incremental capability of the smallest motor and to provide a large number of force and torque increments which can approximate a smooth control of force and torque in forward and reverse directions. The type of motor used for this invention is a multiple-two-node-open-circuit-armature-winding motor as disclosed in the referenced patents. This type of motor offers various levels of energizing the motor to the full force and torque capability.
