WebA variable resistor is a resistor of which the electric resistance value can be adjusted. A variable resistor is in essence an electro-mechanical transducer and normally works by sliding a contact (wiper) over a resistive element. When a variable resistor is used as a potential divider by using 3 terminals it is called a potentiometer. WebFeb 6, 2013 · 1) In the attached mc-60v4 schematic (mine) there's a start-up sub-circuit, I believe, centered on U2_A (under the speed control pot) connected through R20 to leg L (Low) (this is only faintly labeled on my schematic, I see). On Tom Rollins' schematic, he shows that to be connected to leg W (Wiper). 2) Between R7 near U2_D (below the LED …

WebYou can put a speed control on a PSC motor by adding an external variable resistor (or “potentiometer”) to the motor’s wiring. This will allow you to adjust the speed of the motor by rotating the potentiometer. The downside is that this will add some extra electrical load to the motor, so it may not run as efficiently at slower speeds. tapped bar palace diner
