Article explains basic fan-speed control techniques using MAX1669, MAX6650, and MAX6651. Circuits regulate the actual speed of the fan and allow the construction of a temperature-based fan-speed controller. ICs control multiple 3-wire fans.

Sensored position and speed control for a BDC motor (Brushed DC Motor). Position measurement is implemented using a QEP (Quadrature Encoder) shaft sensor. The H-bridge converter is used to drive the motor with the PWM modulation technique for both directions.

When the potentiomenter is all up, the Rcharge resistance is 1, 0 Kohm (the diode prevents the capacitor to charge through the second potentiometer section and the other 1, 0 Kohm resistor) , and Rdischarge is 21 Kohm, giving a 5% on duty cycle and a 1Khz frequency.

Fan noise is becoming a larger issue as more electronic equipment enters the office and the home. A variable speed fan permits slower, and quieter, fan speed when temperature conditions allow.
