Connecting a 220V / 50Hz washing machine to a 220V / 60Hz network

Alexander asks:

Good day to all!

A Bosch automatic washing machine 220 V, 50 Hz with electronic control was brought to the ship. In the marine network 220 V, 60 Hz and electronic control malfunction in the middle of the washing process. I thought about choosing a frequency converter to connect the entire washing machine (see the attached diagram), but I can’t decide: what power, which manufacturer, what characteristics should be taken into account in the first place. If there is any way to solve this problem, tell me, please.

PS. Return of the car is not provided.

Thanks in advance!

The answer to the question:

Good afternoon, a rather complicated question, the failure may not be due to the frequency - the electronics on it, in fact, are on the side. The engine develops those revolutions that the control unit will command him according to information from the speed sensor, unless of course it is a standard household automatic washing machine. But a single-phase load can fail when powered from a network with an isolated neutral (as in your case). Is 220V phase or line voltage?

A conventional frequency converter is not suitable here. Even single-phase models have a three-phase output, and indeed all the chastotniks are designed for a load in the form of an electric motor.

There are such devices as inverters VH-TOR 220/50 Hz - 110/60 Hz. They come in power up to 3 kW, you can already feed the machine from it through a 110-220V transformer of the corresponding power rated at 60 Hz.

You can order from a specialist in electronics a converter made according to the Polyakov circuit published in Radio Journal No. 3, 2000 with modernization in the form of powerful transistors at the output.

Unfortunately, I don’t know any ready-made solutions, but I couldn’t find any profitable offers on the net.
