In this post I have explained the making of a simple 3 phase induction motor speed controller circuit, which can be also applied for a single phase induction motor or literally for any type of AC motor. When it comes to controlling the speed of induction motors, normally matrix converters are employed, involving many complex […]

High Wattage Brushless Motor Controller Circuit
This versatile Brushless (BLDC) motor controller IC is featured to control any desired high voltage, high current, hall effect sensor equipped 3-phase BLDC motor with extreme accuracy and safety. I have explained the details in depth. Using the IC MC33035 The “hero” of the circuit is the single chip controller MC33035 which is a high […]
Very Simple BLDC Motor Driver Circuits using Back EMF
In this post we investigate what’s a BLDC motor and subsequently I have explained regarding the design of a sensorless BLDC motor driver circuit. BLDC CPU Fans Seen those fast moving fans in CPUs, voltage stabilizers, DVD players, and other similar equipment, which work with utmost efficiency, consuming minimum space, current and yet are able […]
Borewell Motor Pump Starter Controller Circuit
In this post I have explained a circuit which controls a submersible borewell motor by operating its red (Start) and green (Stop) buttons, in response to low level, high level water conditions, and also in a condition where the motor may experience a dry run situation. The idea was requested by Mr. Vamsi. Automatic Start/Stop […]
Delay based Motor Speed Controller Circuit – Timer Controlled
In this post I have explained a delay OFF adjustable motor controller circuit so that the motor can be assigned a fixed predetermined operating time, or delay OFF time. The idea was requested by Mr. Cribey Technical Specifications I really like your website. It is very helpful for so many people. I am trying to […]
PWM Motor Soft Start Circuit to Prevent High Consumption during Power Switch ON
In this post I have explained an effective PWM motor soft start circuit which can be used for enabling heavy motors with a soft start and thus prevent the equipment from drawing dangerous high currents. Why a Soft Start High wattage motors such pump motors or other forms of heavy industrial motors tend to draw […]
