A shaft is connected to an electric motor to transfer power. The electric motor consumes 10-amp current at an operating voltage of 110 V. The torque measuring device at the end of the shaft ineasures a torque of 10.2 N-m at a rotational speed of 1000 rpm. Calculate power consumed by electric motor and power transmitted by the shaft. Is the shaft transferring 100% of the power consumed by the electric motor?

Respuesta :

Answer:

shaft is not transform 100% power

Explanation:

given data

current = 10 amp

voltage = 110 v

torque = 10.2 Nm

rotating speed N = 1000 rpm

solution

we get here first power that is consume by motor is express as

power = current × voltage   .........1

power = 10 × 110

power = 1100 W

and power that transmit by shaft is express as

power = T × ω

power = T × [tex]\frac{2\pi N}{60}[/tex]  

power = 10.2 × [tex]\frac{2\pi 1000}{60}[/tex]

power = 1068.14 W

so we can say from above both power

shaft is not transform 100% power
