This paper presents a soft-start circuit using the pulse width-modulation (PWM) method. The motor is controlled by the dc chopper associated with a low-cost PWM chip TL494. The design criteria are ...

This paper designs a kind of variable speed control system of a brushless DC motor (BLDCM) without a rotor position-sensor. Based on intelligent power module and DSP, this system uses the back ...

This braking system was a part of my second year project at VIT Bhopal. Arduino UNO, Motor, motor driver, HC-SR04 sensor and breadboard were used to build a cheap, yet efficient braking system with ...
