Question

The total flux per pole of a reconnected motor is 900,000 lines of force. If the cross-sectional area of the laminated core is 6 sq in. and the cross-sectional area of the teeth per pole is 14 sq in., the flux density in the teeth is approximately

A. 120,000 lines B.98,300 lines C. 105,000 lines D.101,000 lines

Which of the following pitches is the minimum recommended pitch for a 24-pole motor with 360 slots?

A.10 slots B.8 slots C. 12 slots D. 15 slots

Answer 1

SOLUTION:

Given that, total flux per pole of a recconected motor is 900000 lines.

Cross sectional area of the laminated core = 6 sq.in

Cross sectional area of the teeth per pole =14sq.in
