Rotor for a permanent-magnet excited electrical machine
View Patent ↗The disclosure relates to a rotor for a permanently excited electric machine. The rotor includes a holding pocket which is formed by a cutout of the rotor and which is designed to receive a permanent magnet. At least one flexible limb projects into the holding pocket of the rotor, and is designed to form an interference fit together with a circumferential boundary of the holding pocket and the permanent magnet arranged between the at least one flexible limb and the circumferential boundary.
1. A rotor for a permanently excited electric machine, the rotor comprising:
a holding pocket formed by a cutout of the rotor and designed to receive a permanent magnet; and
at least one flexible limb projects into the holding pocket and designed to form an interference fit together with a circumferential boundary of the holding pocket and the permanent magnet arranged between the at least one flexible limb and the circumferential boundary,
a support supporting the at least one flexible limb, the support is connected integrally to an inner boundary, wherein the support projects from the inner boundary, the support comprising a tip wherein the tip of the support and the flexible limb are not directly fixedly connected to one another,
wherein one end of the flexible limb is integrally connected to a radial boundary and another end of the flexible limb is a free end.
2. The rotor of claim 1 , wherein the at least one flexible limb is supported by a support.
3. The rotor of claim 1 , wherein the at least one flexible limb projects into the holding pocket from a radial boundary of the holding pocket.
4. The rotor of claim 1 , wherein the circumferential boundary runs in a closed manner.
