3-phasesynchronouspermanent magnet

Santroll’s advanced Permanent Magnet Synchronous Motor (PMSM) features a stator built with flat wire hairpin windings, delivering exceptional performance, reliability, and efficiency for demanding applications. Unlike traditional motors that use round wire windings, Santroll’s PMSM adopts a hairpin winding stator using rectangular (flat) copper wire. The conductors are pre-formed into U-shaped “hairpins,” inserted into stator slots, and laser-welded into a rigid, high-density winding structure. This design offers a number of significant advantages: High Slot Fill Factor: Hairpin windings allow more copper per slot, enabling higher torque and power density in a compact footprint. Improved Thermal Performance: Flat wire geometry enhances heat dissipation, supporting sustained high-current operation without overheating. Lower Resistance and Power Loss: Reduced I²R losses translate into higher system efficiency, particularly under load-intensive conditions. Superior Mechanical Stability: The rigid winding structure minimizes vibration and deformation, increasing durability and lifespan. Santroll’s high-level automated production lines are key to the reliability and scalability of its motor products. By integrating precise robotic handling, automated coil insertion, and laser welding, Santroll guarantees: Consistent coil geometry Uniform electrical characteristics Reduced human error and defect rate Main Application Areas: Pure electric SUVs, MPVs, electric logistics vehicles, electric buses, Electric boats, etc. Can be integrated with the reducer to form a drive unit.
