Rotor structure for interior permanent magnet electromotive machine |
摘要 |
<p>A rotor structure (10) for an interior permanent magnet (IPM) electromotive machine (8) is provided. The rotor structure (10) may include at least one rotor lamination (12), which in turn may include at least one slot arranged to receive at least one permanent magnet (16). The slot divides the rotor lamination (40) into a pole region (18) and a yoke region (20). At least one bridge (44) is arranged to connect the pole region (18) to the yoke region (20) at an outer edge (24) of the lamination (52). The outer edge (24) of the lamination (52) is profiled along a segment (26) of the bridge (44) to define a concave curved profile (28) for the bridge (44). The concave curved profile (28) for the bridge (44) allows to selectively size a thickness of the bridge (44) to affect at least some electromagnetic and/or mechanical characteristic of the machine.
