AI Technical Summary
The magnetic bridge and ribs of the built-in permanent magnet synchronous motor have magnetic leakage, which leads to mutual constraints between electromagnetic performance and mechanical strength, as well as low material utilization and low processing efficiency.
The rotor adopts a modular rotor design, dividing the rotor core into several modular core layers, which are fixed by fastening rods, connecting frames and fixed end caps to avoid mutual constraints between mechanical strength and electromagnetic performance. The modular core layers are manufactured using small pieces of plate or cutting scraps, and special fastening rods and connecting frames are used to replace the traditional magnetic bridge and rib structure.
It improves material utilization and processing efficiency, avoids permanent magnet leakage and local saturation, enhances the electromagnetic performance and mechanical strength of the motor, and simplifies the assembly process.
