Electrical machine having 5 pole-pairs is supplied with 20 Hz. Peak value of induced back-emf is 120 V. Let's assume there is (0°) zero degrees between rotor and stator and at this moment peak back-emf is induced. What will be mechanical angle between rotor and stator in 0.03 seconds from that moment? What will be an induced back-emf in 0.03 seconds? Angle between rotor and stator deg
