    摘要： A rotor structure for an interior permanent magnet (IPM) electromotive machine is provided. The rotor structure may include at least one rotor lamination, which in turn may include at least one slot arranged to receive at least one permanent magnet. The slot divides the rotor lamination into a pole region and a yoke region. At least one bridge is arranged to connect the pole region to the yoke region at an outer edge of the lamination. The outer edge of the lamination is profiled along a segment of the bridge to define a concave curved profile for the bridge. The concave curved profile for the bridge allows to selectively size a thickness of the bridge to affect at least some electromagnetic and/or mechanical characteristic of the machine.
