Latest Patents
Ji Dai's latest patents focus on the development of hairpin wire motor stators. The first patent describes a hairpin stator that includes a core, slot-positions, and hairpin wires. The core features a first side and a second side, with slot-positions arranged circumferentially to form M radially-adjacent slot-position layers, where M is an odd number greater than or equal to 5. The hairpin wires are configured in these slot-positions and connected to create multiple windings. The design incorporates first U-shaped wires at the outermost slot-position layer and second U-shaped wires at the innermost layer, enhancing the motor's efficiency.
The second patent also pertains to a hairpin wire motor stator, which includes an iron core, a plurality of slot-positions, and hairpin wires. The slot-positions are arranged in the circumferential direction of the iron core, forming adjacent slot-position layers in the radial direction. Each polar region of the iron core contains phases, with each phase including phase slots. The hairpin wires are strategically arranged in the slot-positions of the phase slots, allowing for effective windings and improved performance.
