Thanks to everyone who replied for their input. I am very poor on electrical matters but believe it is induction - don't know enough to say whether Single or Triple phase.
Things have surprisingly improved . I took the blade and the blade mount of allowed the unit to cool for an hour or so...
The motor in my Eumenia RAS ( Model ML50L)appears to have seized - sorry to say it's my fault as it was struggling with a long heavy rip and jammed two or three times despite me trying to be sympathetic to it and releasing as soon as possible.
I am based on South side of Glasgow anyone know...
