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.
PWM generator & DC motor speed control circuit using IC NE 555. PWM Pulse Width modulation was used to control the speed of the DC motor Timer IC pwm signal

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.
Pulse width modulation, supplying energy in form of pulses, to control power supplied to loads. DC control using 555 Timer and AC control using SCRs.
This be Motor Speed Control Circuit 24 Volt at current 20Amp. By it uses IC SG3526Bcontrol in the character PWM that receive like very much and drive motor
The main objective of this project is controlling speed of BLDC motor and displays its speed using an IR method of speed sensor mechanism. Edgefx Technologies provides this electrical project for final year engineering students.
