Can i run a motor (3-phase 230 V) on 440 volt?
Assumption Constant Nameplate Frequency (230 VAC/60Hz to 440 VAC/60 Hz not 440 VAC/400Hz)
Technically possible. If the motor is one of US major manufacturer, is < 30 years old and not, the insulation is rated for 600 VAC. Therefore you can electrically operate a 230 VAC motor on 440. It actually will run more smoothly and cooler. HOWEVER, the total shaft power is directly proportional to voltage. Going from 230 to 440, without changing the stator connection (lead wires) will increase the shaft power accordingly. The mechancial design will not be rated for this increase in shaft power and the motor will mechanically fail (I have seen fires). Also, the motor was tested by the manufacturer at the rated voltage, so operating the motor at a different voltage is NOT RECOMMENDED. (Remember my comment about fires).
Many US motors are dual voltage rated (230/460) and have the stator leads to support the different voltages. However, you quoted 440V. If you connect a 460 VAC motor to a true 440
