Answer / kj

With an induction motor the speed is dependant on the
frequency and is the same as the frequency minus slip. For
a 4 pole motor this is about 1440 to 1460 RPM.
It does not depend on the voltage. The torque is dependant
on the voltage.
A 400 volt motor supplied at 250 volts would not have
anywhere the power output.
