AI Technical Summary
Technical Problem
Traditional rotor assemblies, while ensuring structural strength, suffer from significant eddy current losses, which affect motor efficiency.
Method used
The design employs a clamping plate structure and a support block. By moving the support block radially through the mutual approach or distance of the clamping plates, the magnets are tightly pressed together, isolating the metal clamping plates from the magnets and reducing eddy current losses.
Benefits of technology
This improves the structural stability and working efficiency of the rotor assembly, reduces eddy current losses, and ensures the high-efficiency operation of the motor.

Abstract
The utility model discloses a rotor assembly and disc type motor. Rotor assembly includes pivot, cage, a plurality of magnetic steel, a plurality of support block and fixed ring. The cage includes the clamping plate structure and a plurality of supports, and one magnetic steel is equipped between every two adjacent supports, and a plurality of support blocks abut at the first end of a plurality of magnetic steel, and form cooperation between with the clamping plate structure, and the fixed ring surrounds the outer circumferential side of the second end of a plurality of magnetic steel, and the clamping plate structure includes the first clamping plate and the second clamping plate, when the first clamping plate and / or the second clamping plate are subjected to external force, and make the first clamping plate and the second clamping plate move towards the direction of mutual approach, drive a plurality of support blocks to move outward along the radial of pivot or have the tendency of moving outward, so that a plurality of magnetic steel is pressed to the fixed ring. The utility model makes the position of magnetic steel more stable and reliable, is not easy to shift, can better guarantee the working stability of rotor assembly, makes the rotor assembly intensity better and the working efficiency higher.
