<p>The invention relates to an improved structure of medium frequency and low speed electrical machine, in particular suitable for machine with large number of poles. Rotor is of permanent magnetic or electrically excited or induced, and number of poles is more than or equal to 8, armature windings consist of solid conductor and are arranged in layers with equal or varying pitch in slot, each turn of conductor adjacent to wall of the slot. Compared to the prior art, the invention save copper and ferrum, improve efficiency and easy to manufacture winding. It also applies to other cases except to replace common medium frequency machine.</p> |
