Potentiometer (IEC). Servo Motor. Voltmeter. Ammeter. Reed Switch. Bridge Rectifier. AC-DC Converter.

Adjustable AC speed controls from Grainger can operate on 60/50 Hz at plus or minus 10% rated line voltage. Units help operate universal, shaded pole, and PSC 1-phase AC motors used to run fans, blowers, pumps, vibratory feeders, and heating and lighting applications. Potentiometer, single turn, 5 kΩ, linear taper (Radio Shack catalog # 271-1714) Small "hobby" motor, permanent-magnet type (Radio Shack catalog # 273-223 or equivalent) For this experiment, you will need a relatively low-value potentiometer, certainly not more than 5 kΩ. CROSS-REFERENCES. Lessons In Electric Circuits, Volume 1, chapter 2 ... Rheostats, like potentiometers are glorified variable resistors. While they can be used to adjust the speed of a DC motor, its a big no-no on AC motors. AC motors need to run at preset voltage, motor speed, and current draw. It is a balanced system.

Modern AC motors and drives have narrowed the performance gap with their DC counterparts, but general-purpose DC motors still outperform general-purpose AC motors by many measures. To obtain comparable low-speed performance from an AC motor, much more expensive AC-inverter duty motors and VFDs must be used.

Hi everyone, My goal is to control the speed of a motor (connected to a fan) to control the exhaust temperature of a wood burning. I read a lot of articles about controlling AC motor with triac/opto but all of these solution involve to built the AC "shield" and i'm not confortable to play with 220VAC.Throttle pot. Looks for signal less than 0.25 volts. Throttle pot/airflow meter signal conflict. Looks for throttle pot signal above 2.25 volts while AF signal indicates light load. Defaults to ignore throttle pot signal above 1.5 volts therefore open loop operation with full load enrichment is disabled. Throttle pot/airflow meter signal conflict.
