  • Internal rotor with rotor plate having sprung web-shaped clamping element to clamp the magnet and two recesses
    Patent number: 11424649
    Abstract: An internal rotor for an electric motor has a laminated rotor core with a multiplicity of rotor plates, and multiple pockets in each of which pocket a rotor magnet is at least partially arranged. The rotor plates have first recesses for forming the pockets and at least a first rotor plate which has at least a second recess associated with a first recess. A sprung web-shaped clamping element is formed between the second recess and the associated first recess, and tensioned toward the second recess by the associated rotor magnet to apply a force to the associated rotor magnet toward the first recess in order to hold the associated rotor magnet in the pocket. A rotor plate holds a rotor magnet in a pocket of a laminated rotor core.
