A 230V series motor with 4-pole, 600 conductors wave-connected supplying a load of 7.5kW by taking 30A from the motors. Calculate the developed torque if the flux per pole is 15mWb and its armature circuit resistance is 0.5Ω

The maximum amount of voltage is induced time(s) in 3600 of mechanical rotation for a single loop coil rotating between a north and south magnetic poles of a DC generator. a) one b) two c) four d) none of the above

A DC generator has eight poles, wound as lap then rewound as a wave, calculate the electrical motive force generated in each case if you know that the number of conductors in the armature slots is 240 . The magnetic flux of each pole 0.04  Wb. It runs at 1200 rpm
