If you mean 45 Hz current is input to an inverter, there is no change to the electric motor. The inverter changes the input current to DC and then converts the DC to AC.

I think the question is a little different. The inverter is producing 45 Hz.
The motor will run at 90% of full speed, so about 2550 rpm. That is not exact, it depends on what the motor is driving.
The shaft power will also be about 90%, so approximately 8.4 kw maximum.
The torque capability remains about the same, but the RPM is lower, so the maximum power is lower in proportion.
The motor is not actually "given" a certain power. The motor takes only the power needed to operate the load. If the load is larger, it will take more power, if less, it will take less power. So the power mentioned is the maximum power the motor can take without excess current and overheating.
