In this article I have explained a circuit design which will help to optimize the torque of an induction motor used in electric vehicles, by analyzing its current consumption. Using a IC 555 Inverter for Toque Control The design is specifically intended for electric vehicles which are designed to work with induction motors, and therefore here […]

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 […]
How Stepper Motors Work
In this post I have explained about stepper motor. We will be exploring what stepper motor is, its fundamental working mechanism, types of stepper motor, stepping modes, and lastly its advantages and disadvantages. What is stepper motor? Stepper motor is brushless motor; its rotating shaft (rotor) completes one rotation with a determined number of steps. […]
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 […]
Greenhouse Motorized Water Diverter and Humidity Controller Circuit
In one of the previous posts I have explained the making of a greenhouse temperature controller circuit, here we study how the effects may be enhanced through an automatic water valve actuator and humidity controller circuits. The idea was originally requested by Mr. Leandros Komninos Technical Specifications Found one on ebay, these are the detail […]
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 […]
