The short circuit and no-load tests of a 400 volt 56-pole three-phase asynchronous motor are as follows. Idle test: 400 volts, 8 amps, power factor 0.16. short circuit test: 200 volts, 39 amps, power factor 0.36. Since the motor draws a nominal 30 ampere current from the network, (rotor and stator losses will be considered equal) Calculate the shaft power (Pm) and shaft torque (Mm)?

Calculate the shaft power (Pm) and shaft torque (Mm)?
A) Pm= 7.43 kW , Mm=89.33
B) Pm= 7.42 kW , Mm = 89.23
C) Pm= 7.41 kW , Mm=89.13
D) Pm= 7.44 kW , Mm = 89.43
Given: The short circuit and no-load tests of a 400 volt 50 Hz, 6-pole three-phase asynchronous motor are as follows:
Idle test: 400 volts, 8 amps, power factor 0.16.
Short circuit test: 200 volts, 39 amps, power factor 0.36.
Since the motor draws a nominal 30-ampere current from the network (rotor and stator losses will be considered equal).
To find:
