Another of the many similar configurations we have in this section. This one is from a Radio Electronics magazine from June 1985. The transistor is according to the power of the controlled motor.
We found this circuit in a 1977 radio documentation. The circuit uses TTL frequency dividers from...
In figure we have a three-phase AC motor control for voltages up to 600 V or 1200 V depending on...
The oscillator shown in the figure can generate signals up to 500 kHz and has good stability. Coil...
