what will happen if I connect a 110v motor to a 220v supply
CAUTION/REMINDER: You can use a 220V motor on a 110V source and the TOP speed will be HALF of what it should be and there will be NO damage to the motor. BUT ..if you use a 110V motor on a 220V source it will run at TWICE the TOP speed and permanently damage the motor (it may even catch fire).ow you will need to buy an AC STEP-UP transformer. This steps up the voltage from 110V to 220V and still keeps it as AC voltage. Make sure that the OUTPUT Power rating of the transformer is GREATER than the power you calculated for your machine by approximately 25%.
