Fridge compressor motors require steels with a low loss level. Non-oriented fully processed electrical steels have guaranteed magnetic properties. As well as the maximum loss and minimum polarisation levels cited, full magnetic characterisation curves regarding losses, polarisation, permeability and apparent power at different frequencies are available on request.
In order to meet the the specific requirements of this application, we would recommend the M230-35A. The use of M350-50A is also possible. The magnetic properties of semi-process are developed during the final annealing cycle, which is performed by the client after punching the laminations. This annealing treatment reduces losses and improves permeability and polarisation, as a result of recrystallisation, grain growth and also - for certain grades - decarburisation.
In order to meet the the specific requirements of this application, we would recommend the M340-50K. The use of M450-50K is also possible.
