Two conductor rheostat
Webdimensions of the conductor can easily be determined as follows. Consider a conductor satisfying Eq. (3.3) to be in the form of a slab of length l and cross sectional area A [Fig. 3.2(a)]. Imagine placing two such identical slabs side by side [Fig. 3.2(b)], so that the length of the combination is 2 l. The current flowing through the ... WebEb = PΦNZ / 60A. Where; P = Number of poles. Ф = Flux per pole. N = Speed of motor (RPM) Z = Number of conductors. A = Number of parallel paths. Once the motor is designed, the Number of poles (P), Number of conductors (Z), and Number of parallel paths (A) cannot change. So, these are fixed quantities.
