I THINK BRUSHLESS DC MOTOR IS DA RIGHT ANSWER.

MANY OF MY FRIENDS CHOOSE STEPPER MOTORS FOR
THEIR CORRECT ANSWER.BUT AS STRPPER MOTOR BUT
BRUSHLESS DC MOTOR.

STEPPER MOTORS ARE USED FOR SAMLL STEP SIGNALS
WHERE AS BRUSHLESS DC MOTORS ARE USED AS PER SPEED
SIGNAL AS GENERATED IN CPUs.

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
