Ql: A: A single phase 240 volt 50 hertz capacitor start induction motor has a run winding which takes 4 amperes at 0.6 lag power factor at start while the start winding/capacitor takes 3 amperes at 0.8 lead power factor. Determine:- a) the phase angle of each current and the angle between them. b) the total current taken by the motor at starting. c) the voltage across the 35uF capacitor. B: A single phase, 240 volt, 50 hertz, 4 pole split phase motor runs at rated speed of 1425 r.p.m. For full load determine:- a) the synchronous speed of the motor. b) the slip speed. c) the slip percent. d) the rotor frequency. C: Show the difference between the running (permanent) capacitor and the start сараcitor.
