Murugesh Kumar, 'Electric Machines', Vikas Publishing House Pvt. Ltd, 2002. Induction And Synchronous Machines-K Murugesh Kumar 2000-12-01 This book is a sequel to the author's DC Machines & Transformers. Comprehensive, lucid and student?friendly, it adopts a self?study approach and is aimed at demystifying the subject for students who consider 'Electric Machines' too tough. The book covers Answer (1 of 2): The power formula for 3 phase induction motor is as follow. Power= √3 × V × I × Cos fi Where in V is supply voltage, I is current, Cos fi i.e power factor Is 0.8 for inductive load. 7.5 HP = 7.5 × 750 = 5625 Watts. 5625= 1.732 ×415×I×0.8 Current I = 5625/(1.732×415×0.8) Ful The synchronous speed is: The rotor speed is the synchronous speed minus the slip speed, which can also be calculated as: The slip speed is the synchronous speed times the slip: The slip frequency is the slip speed converted to Hertz: f_slip = n_slip / 60 = 72/60 = 1.2.
