The full load speed of a three-phase four-pole 50Hz, 160kW induction motor is 1,475rpm. The starting torque is 170%, the yield torque is 280% of the rated torque, and the moment of inertia of the rotor is 2.5kg-m ^ 2. The torque of the load converted to the motor shaft is 800 N-m at full load speed and the moment of inertia is 20 kg-m ^ 2. a) Find the starting time when the load torque is assumed to be...
