AC Motor Rotor Core
- Material Options: Non-oriented silicon steel (35A300–50W470) or cobalt alloy for high-efficiency AC systems.
- Low Iron Loss: ≤ 2.0 W/kg @ 50 Hz, improving motor efficiency under alternating load.
- High Magnetic Saturation: Flux density ≥ 1.6 T supports strong torque output without saturation distortion.
- Precision Slot Geometry: Slot tolerance ± 0.01 mm ensures uniform air-gap and torque balance.
- Surface Smoothness: Rotor OD roughness ≤ 0.8 μm ensures efficient magnetic coupling with stator.
