Power output =Torque *angular speed
Angular speed should be in rad/sec
Therefore above question power output=5*2*pi*ns
Pi=3.14
ns is the rotation per sec=rotation per minute/60
Which gives output power=926.769W
Input power =(3)^.5 *(supply voltage)*(supply current) * power factor......( As this is three phase supply)
Supply voltage=208V
Supply current=6.5A
Power factor=.88
Which gives us input power =2060.72W
Therefore losses in machine=input power - output power
Which gives losses=1133.95W
