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 7 storey building has a floor area of 35,000sq.ft on each storey. On the ground floor 11KV electrical sub-station is to be erected. A load of 3kw for every 400sq.ft (p.f is 0.8) is proposed for each floor. fire pump 7.5hp, water pump 5hp, lift 2 nos, each 10hp and 20shop load of each shop is 5kw. calculate a. load each floor b. total load of building c.
