2 Simple Washing Machine Circuits Explained
In this post I have explained how to make a couple of simple washing machines using a bidirectional single motor with timer and a simple version using cam shaft mechanism, cheaply. In the first design we use a bidirectional, alternately rotating clockwise and counter clockwise with a pause in the middle: Audio/Video Representation Circuit Working […]
Borewell Motor Pump Starter Controller Circuit
In this post I have explained a circuit which controls a submersible borewell motor by operating its red (Start) and green (Stop) buttons, in response to low level, high level water conditions, and also in a condition where the motor may experience a dry run situation. The idea was requested by Mr. Vamsi. Automatic Start/Stop […]
Delay based Motor Speed Controller Circuit – Timer Controlled
In this post I have explained a delay OFF adjustable motor controller circuit so that the motor can be assigned a fixed predetermined operating time, or delay OFF time. The idea was requested by Mr. Cribey Technical Specifications I really like your website. It is very helpful for so many people. I am trying to […]
PWM Motor Soft Start Circuit to Prevent High Consumption during Power Switch ON
In this post I have explained an effective PWM motor soft start circuit which can be used for enabling heavy motors with a soft start and thus prevent the equipment from drawing dangerous high currents. Why a Soft Start High wattage motors such pump motors or other forms of heavy industrial motors tend to draw […]
