Abstract
A permanent magnet rotor of a motor including a rotor core and permanent magnets. The rotor core includes a central core, a plurality of sectional cores, and a connecting mechanism. The sectional cores are integrated with the central core via the connecting mechanism to form a whole iron core. Grooves are formed between each sectional core and the central core and the permanent magnets are embedded in the grooves. The permanent magnet rotor has a simple structure, excellent manufacturability in terms of production and assembly, low manufacturing costs, excellent electromagnetic performance, and meanwhile is robust enough to avoid potential deformation.
