A BLDC motor is energized by a 100 V dc source. The armature resistance of the winding is 1.0 ?. The no-load speed of the motor is 1000 rpm at 100% modulation factor. Compute the motor speed when the load torque is 9 Nm. Also compute the drop in speed if the load torque increases to 15 Nm without any change in the voltage.
