Section 13.5: Performance Equations cont.
A lap-wound armature has 576 conductors and carries a current of 123.5 A. If the flux per pole is 20 mWb., calculate the electromagnetic torque developed by the armature.
The armature is lap-wound so p = a. Then the torque equation yields:
= 20´10-3Wb.´576´(p/a = 1)´123.5A./(2p)
