... and electric properties. One more remark has to be mentioned. The severe constraints imposed for the motor operation ask for a special design where the value of the electromagnetic loads goes toward upper limits and beyond them. It is mandatory the use of superior materials (for example high quality ferromagnetic laminations) and the presence of ...
