If it was 440 v single-phase, use half the number of turns in the windings, but use thicker wire of double the cross-section. Or to use the same wire again, fold the wire once into half its length and use that.
Remove the motor from the system. Get the motor rewound at a motor rewinding shop. Replace the motor back into the system. While the motor is at the rewind shop find out why the motor burnt out. The first thing that should be checked is the overload protection. Make sure that is is the same as the motors full load amps.
For a single-phase induction motor, allow 7 amps on a 240 v for a 1-HP motor. Therefore the formula is: current = 7 X HP x 240 / voltage
fan is a capacitor start capacitor run single phase induction motor. since single phase induction motors are not self starters, caused by discontinuty in stator mmf. so to iniate rotation single phase supply is splitted 90 degree apart by a capacitor to convert it to a 2 phase motor, which produces a continued synchronously revolving mmf in stator to start the motor. cool !!
Single phase motor winding is often checked just by listening to the noise that the motor is making. An experienced person can tell if the motor is working at single phase or double phase.
With a synchronous motor shorting the slip-rings together should make it work as an induction motor although perhaps not to an optimal degree.

I want to purchase some tools for electrical motor rewinding work hence please give me list of tools available to u with price list. E-MAil- davidph68@hotmail.com
To calculate the HP of a motor, you can use the formula: HP = (Watts x Efficiency) / 746 Where Efficiency is a typical value between 0.7 and 0.9. For a 3 amp motor, you will need to know the voltage to calculate the wattage and then convert it to HP using the formula above.
Well it usually involves rewinding the stator or rotor. Depending on the motor and what actually failed it's probably cheaper to just buy a new one.
To do it properly would require rewinding the motor with thicker wires in order to deal with the higher current caused by the higher voltage.
To rewind a single phase motor with a double capacitor, first disconnect the motor from the power source and remove it from the equipment. Then, carefully disassemble the motor to access the windings, taking note of the wiring connections before removing them. Rewind the motor windings by matching the original wire gauge and number of turns, and reconnect the windings following the wiring diagram for the double capacitor setup. Finally, reassemble the motor and test it to ensure proper functioning.
The motor cannot be altered to work on single phase power. You will either have to put in a new single phase motor or use a phase convertor box. Do a google search for phase convertor - you will find plenty.
The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.
