Induction motor:Condition for Maximum Starting Torque
The induction motor has a star-connected rotor and when the stator is connected to a supply of normal voltage, the induced e.m.f. between the slip rings at standstill is 80 V. Calculate the current in each phase and the power factor at starting when (i) the slip-rings are shorted, (ii) slip-rings are connected to a star-connected …

Induction Motor Formulas with Calculations
Motor Slip. Slip of a motor can be found from the formula: s = (η sync-η m)/ η sync * 100. η sync = Speed of magnetic field. η m = Mechanical shaft speed. Calculation: The rotor speed of a 4 pole induction motor at 50 Hz is 1200 r/min. Calculate its slip. Solution: Rotor speed = η m = 1200 r/min. Where η sync = 120 * 50 / 4 = 1500 …
