Refrigerator Motor Soft Start Circuit
Refrigerators tend to draw appreciable amounts of current each time their compressor switch ON, and this could happen many times per day. A soft start circuit to the compressor motor […]
PWM Controlled Fan Regulator Circuit
In this article we look into a simple 220V mains PWM controlled fan or light regulator circuit which does not require a microcontroller or costly triac drivers for the intended […]
Water/Coffee Dispenser Motor Circuit
The article discusses a protection circuit which may be used for preventing a “dry run” situation in mini coffee dispenser motor pumps, by sensing the slight difference in its wet […]
Washing Machine Motor Agitator Timer Circuit
The article details a circuit design for controlling a washing machine motor agitator through a preset time sequence which also includes an alternate reversing of the motor rotation. The circuit […]
Treadmill Motor Speed Controller Circuit
In this post we discuss a simple, accurate, high torque treadmill motor speed controller circuit which may be effectively installed in similar units for acquiring PWM controlled variable speed feature. […]
