Rotor position sensing of D.C. Brushless motors

Mr. Anand Shwetal I.

Abstract :

The ushless dc motor requires the position and speed sensors for control. Since the system behaves like a conventional separately excited d.c. motor, the speed can be controlled by the variation of the d.c. supply to the inverter or to the field. The speed is inversely proportional to the field current. The torque–speed characteristics are similar to those of a separately excited d.c. motor but is slightly more drooping in this case. There are several possible methods of detecting the rotor position, using sensors like Hall elements or optical sensors
