Question

Q.10 A 4-pole , lap wound 410 Volt series motor has the following data : Number of armature
conductor is 960, flux per pole is 0.04Wb, total motor resistance is 0.50, iron and friction
losses are 2 KW, if the current takes by motor is 95 Amp. Find (1) total torque (2) useful torque
at the shaft (3) power output (4) pull at the rim of the pulley of 42 cm diameter connected to the
shaft.​

Answer 1

Answer:

Explanation:A 4-pole armature of a d.c. machine has 1000 conductors and a flux per pole of 20 mWb. ... (b) For lap wound, c = 2p, hence, generated e.m.f., E = ... 2. A generator is connected to a 50 load and a current of 10 A flows. If the armature ... generator at full load, assuming the iron, friction and windage losses amount to 1 kW.
