    25-11-2016В В· Problems . 1. The input power to a 3-phase a.c. motor is measured as 5kW. If the voltage and current to the motor are 400V and 8.6A respectively, determine the power factor of the system? 3-PHASE INDUCTION MOTORS EXAMPLES OF MOTOR OPERATION At the base of equivalent circuit showing one phase of multi-phase motor we can consider different possibilities of motor operation, depending on its speed n, slip s and, therefore, the values of: resistance s s R ' 1в€’ 2 and the power s s I R в€’ в‹… в‹… ' 1 2 ' 2 2 a) n =n

    The torque produced by three phase induction motor depends upon the following three factors: Firstly the magnitude of rotor current, secondly the flux which interact with the rotor of three phase induction motor and is responsible for producing emf in the rotor part of induction motor, lastly the power factor… Numerical examples 1. EE – 4422 Electric Machine Design THREE-PHASE INDUCTION MACHINES Numerical Examples Problem #1 A 3-phase, 460 V, 100 hp, 60 Hz, 4-pole induction machine delivers rated output power at a slip of 0.05.
