In this post I have explained 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. The idea was requested by Mr. Samuel. Technical Specifications I’ve a treadmill whose power failed completely…it had been imported from china and it’s like […]

Driving 3-Phase Motor on Single Phase Supply
Driving a three phase motor on a single phase supply directly through ordinary methods can be difficult and dangerous. It requires accurately designed circuits for implementing the operations. Here I have tried to present one such PWM controlled three phase motor driver circuit. I have explained more. The circuit can be understood with the following […]
Single Phase Variable Frequency Drive VFD Circuit
In this post I have explained a single phase variable frequency drive circuit or a VFD circuit for controlling AC motor sped without affecting their operational specifications. What is a VFD Motors and other similar inductive loads specifically do not “like” operating with frequencies that might be not within their manufacturing specs, and tend to […]
Operating a DC Motor Clockwise/Anticlockwise with a Single Switch
The following post discusses the wiring connections for driving a DC motor in clockwise and anticlockwise directions with the help of a single toggle switch and a relay circuit. The idea was requested by one the interested followers of this blog. I have explained more: Technical Specifications We have our project in school. Our professor […]
Climate Dependent Automatic Fan Speed Controller Circuit
The following circuit of a temperature or climate controlled automatic fan speed regulator circuit was requested by one of the followers of this blog Mr.Anil Kumar. I have explained more about the proposed design. The Design As can be seen in the given diagram, a very simple concept has been implemented in the proposed design of a climate controlled […]
How to Control Motor with a Cell Phone
In the following post I have explained a very simple circuit idea which can be used for controlling a motor’s rotational direction i.e. for moving it either clockwise or anticlockwise through alternate miss calls from your cell phone. The Circuit Concept I have already discussed a novel cell phone controlled remote switch circuit where the […]
