    The ever increasing market demand for energy efficient systems - from motor vehicles to home appliances, robotics to medical equipment, etc. - is pushing toward the adoption of more and more efficient electric motors like 3Ph-motors (PMSM ,BLDC, ACIM). High efficiency, reduced noise, extended lifetime, rapid time-to-market and all at lower cost.

    The torque-speed characteristics of the BLDC motor are similar to the BRUSHED DC motor, that's why the name BLDC came. The commutation is done in BLDCM is electronically instead of brushes. It is easily controlled through the rotor position sensors and performs well especially in speed/torque.
