<p>A rotor has a core which consists of layers of disc elements of two different types. A disc element of a first type has a number of open slots around the circumference whilst the second type (14) has a suitable combination of open slots (12) and closed slots (10), where electric conducting material (16) is inserted. In the case of a four-pole induction motor, each of the four sections (51,52,53,54) has an identical arrangement of open and closed slots. The disc elements are layered in such a way that each slot has suitably located openings and closings along the rotation axis (20).</p> |
