Q. A four-pole dc machine with 728 active conductors and 30mWb flux per pole runs at 1800 r/min.
(a) If the armature winding is lap wound, find the voltage induced in the armature, given that the number of parallel paths is equal to the number of poles for lap windings.
(b) If the armature is wave wound, calculate the voltage induced in the armature, given that the number of parallel paths is equal to 2 forwave windings.
(c) If the lap-wound armature is designed to carry amaximumline current of 100A, compute the maximum electromagnetic power and torque developed by the machine.
(d) If the armature were to be reconnected as wave wound, while limiting per-path current to the same maximum as in part (c), will either the maximum developed power or the torque be changed from that obtained in part (c)?
Voltage, current, and charge control: The collector-emitter current can be seen as being controlled through the base-emitter current (current control), or through the base-emi
