Servo Motor Working Explained
We know that servo motors already exist for very long time and we also see that many people use them in many applications. These motors look small but they give big power and also they save lot of energy. So now many people who like electronic things and who want to understand more about such […]
Simple Ceiling Fan Regulator Circuit
A simple electronic ceiling fan regulator circuit using a triac and a diac is a common type of circuit which is used to control the speed of a ceiling fan. This circuit basically works using phase control principle, in which the voltage supplied to the fan motor is varied by controlling the firing angle of […]
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 […]
Understanding Scalar (V/f) Control for Induction Motors
In this article I will try to explain how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling […]
5 Simple DC Motor Speed Controller Circuits Explained
A circuit which enables a user to linearly control the speed of a connected motor by rotating an attached potentiometer is called a motor speed controller circuit. 5 easy to build speed controller circuits for DC motors are presented here, first one using MOSFET IRF540, second one using IC 555, the third concept with IC […]
