Abstract

Improvements in feedback control circuits for suspension systems and magnetic propulsion, to linearize the voltage function with respect to the force of a polyphase linear electric motor whose magnetic attraction force generated with respect to a ferromagnetic reaction rail from which it is suspended and physically separated varies directly as the motor current frame and inversely as the square of the separation distance, characterized in that said circuits comprise: means that detect the space that defines the distance of separation and any acceleration of the motor associated with any change in the gap, to produce signals indicative of the extent of the gap and the rate of change of said space; means deriving from said signals a feedback voltage proportional to the force that corresponds to the stabilizing attraction force of the gap, which the motor must produce, and which is sufficient against an opposing force acting on the motor to restore it and keep it in a stable equilibrium position to a predetermined gap; means that supply a polyphase control voltage of variable frequency and constant amplitude; means deriving from said voltage proportional to the force, from said signals and from said polyphase voltage, by phase thereof, non-reactive and reactive feedback voltage components, proportional respectively to the extension of the gap and to the frequency of the polyphase voltage ; and means for feeding the motor a polyphase terminal voltage, which is proportional to each phase thereof to the sum of said reactive and reactive non-reactive voltage components, to thereby produce said attractive stabilizing force at any rising frequency from zero to zero. Said polyphase control voltage. (Machine-translation by Google Translate, not legally binding)
