Each section follows the other via what degree - ANS-a hundred and twenty stages
If a squirrel cage motor rotation is clockwise with ABC segment series, and the section
sequence ACB is applied, which assertion is accurate? - ANS-The motor will run within the
counter clockwise direction
What device is used to save you beginning in wye and delta simultaneously? - ANS-Walking
beam
What is the percentage of slip for a three-section 60Hz motor that has 6 poles and rotates at
1157? - ANS-three.Fifty eight%
1200-1157= forty three
43x100= 4300
4300/1200= 3.58% slip
What is the reason of the blocked rotor check? - ANS-Determines the ordinary initial starting
contemporary.
What is the rotating velocity of a 3-section 30 Hz 6 pole motor? - ANS-600rpm
30x60=1800 P/2
6/2=3 1800/three= 600
What is the rotating pace of a 3-segment 60Hz four pole motor? - ANS-1800rpm
60x60= 3600 P/2
3600 divided by means of 2 = 1800
What is the rotor pace for a 4 pole, 60Hz squirrel cage motor that has a percent of slip of
3.76%? - ANS-1732rpm
What would be the rotor slip frequency for a six pole, 60Hz motor this is rotating at 1170
rpm? - ANS-1.5Hz
60x60= 3600 6p/2
3600/3= 1200-1170= 30
30x100= 3000/1200= 2.Five
2.5=.1/2
.025x60= 1.5Hz
Which of the subsequent exceptional describes the cut up-segment motor? - ANS-It uses the
difference in winding inductance to offset the stages.
Which of the subsequent is a motor that may be run on both AC and DC? - ANS-Universal
