A certain 3-phase induction motor has a torque developed of 345 N-m when running at a slip of 0.01. The rotor copper loss at this slip is 5.69 kW. Assume that the rotational losses are negligible. a) If the rotor circuit resistance is increased by 5 times, determine the torque developed if the slip is also assumed to be increased by 5 times to 0.05. WebReasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. how many different buddha statues are there
