Abstract:
1. A rotor having a squirrel cage and permanent magnets distributed around the circumference, said rotor having a laminated core which extends over an entire rotor region of the rotor and is provided with longitudinally continuous rotor slots, wherein the squirrel cage passes through the rotor slots over the entire length of the laminated core, the rotor slots each include a cage web portion in a radially outer region of the rotor and a cage bar portion in a radially inner region of the rotor, the cage web portion having a width in a circumferential direction of the rotor smaller than the cage bar portion, the squirrel cage is formed with cage bars which are disposed in the rotor slots and with short-circuiting rings which connect the cage bars on both end faces of the laminated core in short-circuiting regions of the rotor, a radius of the entire rotor region is smaller over its entire outer circumference than a radius of the short-circuiting rings by at least a radial thickness of the permanent magnets, and the permanent magnets are mounted on the rotor.
