DC Shunt Motor Controller Circuit using Variac
The simple DC shunt motor controller circuit presented in the following article uses a variac. This design facilitates an instant stopping of the motor at any stage with a flick of a switch, along with reversing the motor direction. It also provides speed control for the motor with a high level of accuracy. Overview TRIAC […]
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 […]
Electronic Engine Speed Governor Circuit
In this post I have explained an electronic engine speed governor or controller circuit using an RPM feedback signal loop through a hall effect sensor network. The idea was requested by Mr. Imsa Naga. Circuit Objectives and Requirements Thank you very much for your time. I believe this circuit would be suitable for a single […]
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 could probably tackle this issue and help save electricity. The idea was requested by Mr. Naeem Khan. Technical Specifications I need your help regarding to […]
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 […]
