Control Of Motors That Do Not Use Commutators

Abstract
A transistorized switching circuit in which two transistors of opposite conductivity are arranged so that they become conductors in response to an input signal that exceeds a critical level, and a positive feedback circuit that is connected between an output and an input of the circuit commutator and that is arranged so as to retain the transistors in conductive condition until the level of the input signal falls below the critical level.
