Pinout/Connection Diagram

 mpsa42 Circuit
Circuit generates variable frequency between 10 and 300 Hz at constant voltage for changing speed of induction motor between theoretical limits of 300and 9000 rpm without affecting maximum torque. Direct coupling between control and drive circuits is used; if motor noise affects control logic circuits, ptoisolators should be usedbetween control and drive sections. Article tells how circuit works and gives similar circuit using optical coupling.-T. Mazur, Unique Semiconductor Mix Controls Induction Motor Speed, EDN Magazine, Nov. 1, 1972, p 28-31.
