BLDC MOTOR THE NEW SPECIES OF ELECTRIC MOTOR

BLDC motor ( Brushless Direct Current Motor) and also known electric commutated motor is multiphase electric motor supported by direct current (DC) that has electronic changed system. So it doesn’t need mechanic commutators. BLDC motor doesn’t brush as excitation and has small losses energy.

BLDC Motor has a maximum torque in stationer condition. But, torque decrease linearity when velocity incrase. When BLDC Motor start, it is produce high torque to rotating motor firstly. After several seconds the torque decrease and increase the velocity. It proves that BLDC Motor has high efficient value.

BLDC Motor has more advantages than DC Motor,. There are :

1.      High torque and speed.

2.      High efficient value

3.      Long life time

4.      No spark in commutator

5.      No rotor winding, so it doesn’t produce centrifugal force

6.      No noise

Beside that, there are two disadvantages of BLDC Motor. They are expensive price and complicated system control. But if we can make system control by yourself, it is no problem to use BLDC Motor in your life.
