120V, 60Hz, 10amperes washer does not work at 127volts, 50Hz?

Question

I have been using Kenmore Ultra fabric Care Heavy Duty 80 Series washer model # 110. 92284100, stock # 22841, serial # cc 3083945 for the last 10 years & performance was very good. Machine rating 120v, 60Hz, 10A. I shifted this machine to in Pakistan. Voltage is 220v, 50Hz. Used auto transformer rating: 2000VA, 127/220V, 50/60Hz. Primary 127V/16A, secondary 220V/10A. During running machine stopped w/o completing the cycle. The TX & machine cable became very hot. Measured input/output current as 8-9A/16-18A. I reduced input voltage thru another TX to 202V and output of 220/127V TX was reduced to 117V and currents measured again as 8A/14A. I have no option except to use at 220V, 50Hz with some transformer.
Need expert opinion/solution to reduce current below 10A so that machine could work without heating. Do I need to reduce the voltage to 100-105V, will it work and will it not heat up due to change of frequency. Please suggest.

Answer 1

If you used the transformer as you described, its output voltage would be over 400 volts. But if you instead used it as a step-down transformer, your output voltage be close to 127 volts. That by itself should be close enough to operate the washer. You are using the transformer at nearly its maximum rating. At best it will get hot and won't last as long as you'd like. At worst, it will break down during the current surges needed to start the washer motors.

But your biggest problem is that the washer was designed to operate at 60Hz. Electronics can easily be designed to operate at both frequencies; motors cannot. Its magnets are saturating too early in the AC cycle, so the motor delivers less power and generates more heat.

Your best solution, and probably your cheapest, is to buy a washer designed for 50Hz, and preferably for 220V.

Answer 2

50 Hz is not 60 Hz. No work. Get new washer for power available. Transformer no change Hz.

Answer 3

You actually require an appropriate step-up transformer, which you can buy it from any electrical shop, and then fit it to the 127V machine. It will work...
