Treadmill Motor Speed Controller Circuit
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 […]
5 Useful Motor Dry Run Protector Circuits Explained
The 5 simple dry run protector circuits presented here shows simple methods by which insufficient water conditions inside an underground tank can be sensed without introducing probes inside the underground tank, and thus preventing any possibility of motor dry running. The circuit also incorporates an overhead water overflow control feature. The idea was requested by […]
Programmable Bidirectional Motor Timer Circuit
In this post I have explained a programmable bidirectional motor timer circuit for controlling a custom industrial mechanism. The idea was requested by Mr. Milton Technical Specifications I am a glass specialist, pretty good with DIY etc, but not too hot on electrics. I am planning a build for a 10mm Toughened Glass Watch display […]
Infrared (IR) Motor Remote Control Circuit
In this article I have explained a simple infrared (IR) remote control circuit which is configured for operating a DC motor in response to the switching made from a standard IR remote handset such as a TV remote or a DVD remote. The connected motor can be moved either ways and also can be made to halt. […]
