Brushless DC motors (BLDC) are widely used in industrial areas. The BLDC motors are driven either by indirect ACAC converters or by direct AC-AC converters. Direct AC-AC converters i.e. matrix converters are used in this paper to drive the three phase BLDC motor and it eliminates the bulky DC link energy storage element. A matrix converter converts the AC power supply to an AC voltage of variab...

A miniature linear synchronous motor was designed, fabricated and tested. Actuation was achieved through interaction of traveling magnetic wave, generated by linear array of microcoils on the stator, and permanent magnets on the rotor. Two configurations of the motor were investigated. One with a single hand-assembled permanent magnet on rotor and corresponding array of multiturn microcoils; th...

Due to their better electrical properties and mechanical features, the usage of BLDC motors is increasing they have replaced conventional DC asynchronous in many applications. This project provides a sensor-based permanent magnet brushless motor for commercial electric vehicles. To improve reliability speed regulation, PID controller employed. The three-phase voltage inverter delivers constant ...
