In this post I will show how to construct a wireless DC motor speed control circuit which can be controlled using any IR based remote controller. The proposed project has two main objectives; the first one is 5 step sequential speed control of a 12V DC motor using IC 555 (PWM) and controlling the PWM […]

Regenerative Motor Acceleration Experiment
In this post I have explained about this special regenerative motor coil overunity phenomena which can be very interesting to the primary level experimenters like us. In this experiment a motor shaft is connected with a disc which has a few number of magnets attached radially at equal distance. An external high impedance coil is […]
Line Laser Controlled Motor Alignment Circuit
In this post I have explained a simple line laser controlled motor driver circuit, which works by responding to a precision horizontal laser line, generated from a line laser level device, and automatically adjusts the alignment of the connected tool or the job work with extreme perfection and accuracy. What is Line Laser The line […]
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 […]
Easy H-Bridge MOSFET Driver Module for Inverters and Motors
If you are wondering if there’s an easy way to implement an H-bridge driver circuit without using the complex bootstrapping stage, the following idea will precisely solve your query. In this article I have explained how to build an universal full-bridge or H-bridge MOSFET driver circuit, using P-channel and N-channel MOSFETs, which can be used […]
Constant Torque Motor Speed Controller Circuit
In this post I have explained a DC Motor controller which features a constant torque compensation for enabling the motor to run at a consistent speed irrespective of the load on it. Drawback of Ordinary Speed Controllers One drawback of the majority of simple speed controllers is they only provide the motor with a predetermined […]
