Found in a 1967 publication by General Electric, this control is intended for motors up to 2 A according to the SCR used. Higher current equivalent SCRs can be used.
In this oscillator a phase shift network formed by C1, C2, C3 and R1, R3, R4 determine the fase...
For inductive loads we have the configuration shown in the figure. Note that the optical coupler...
