Choose the correct option which represents the considering factors to select and install a controller.

Question

A dc compound motor having a rating of 10 kW, 1150 r/min, 230 V, 50 A, has the following losses at full-load: bearing friction loss 40 W brush friction loss == 50 W windage loss = 200 W (1) total mechanical losses = 290 W (2) iron losses = 420 W (3) copper loss in the shunt field = 120 W copper losses at full-load: (4) a. in the armature b. in the series field c. in the commutating winding total copper loss in the 500 W 25 W 70 W armature circuit at full-load = 595 W

4 What determines the power rating of a ma- chine? -5 If we cover up the vents in a motor, its out- put power must be reduced. Explain. -6 If a motor operates in a cold environment, may we load it above its rated power? Why?

An electric motor driving a skip hoist with- draws 1.5 metric tons of minerals from a trench 20 m deep every 30 seconds. If the hoist has an overall efficiency of 94 percent, calculate the power output of the motor in horsepower and in kilowatts.
