Precision-Engineered M19-29G Rotor Laminations - Ultra-Thin 0.35mm Non-Oriented Silicon Steel with Laser-Cut Air Vents for 15% Improved Cooling Efficiency

Precision-Engineered M19-29G Rotor Laminations - Ultra-Thin 0.35mm Non-Oriented Silicon Steel with Laser-Cut Air Vents for 15% Improved Cooling Efficiency

Product Description:

Our VortexFlow-equipped rotor cores are purpose-built for ultra-high-speed machines that spin to 25,000 RPM and beyond. Each core combines patented, spiral-vent geometry with a premium grain-non-oriented (GNO) silicon-steel alloy to deliver exceptional aerodynamic and magnetic efficiency.

• VortexFlow venting — 22 % lower windage loss
  Helical micro-ducts etched into the lamination stack guide boundary-layer air into a controlled vortex, shedding drag while maintaining rotor cooling. The result is cooler bearings, higher mechanical efficiency, and longer service life in turbo-compressors, e-boosters, and high-speed traction drives.

• Precision gauge control — 0.35 mm ± 0.005 mm
  Tight thickness tolerance across the entire coil width keeps electrical and mechanical balance spot-on, reducing vibration and allowing smaller air-gaps at high tip speeds.

• VPI-ready bonding layer
  A factory-applied, high-temperature adhesive cures seamlessly during your vacuum-pressure-impregnation (VPI) cycle. This not only locks the stack but also fills micro-voids, boosting dielectric strength and dampening acoustic noise—without an extra processing step.

• Anti-fretting surface texture (Ra 0.8–1.2 µm)
  Engineered micro-roughness breaks up microscopic slip, preventing fretting corrosion between shaft and core under rapid load cycling. The texture simultaneously improves resin wet-out during VPI, enhancing mechanical cohesion.

Features:

• Dynamic Balancing - Pre-balanced to G2.5 grade at 10,000 RPM
• Thermal Management - 18% better heat dissipation than standard designs
• Manufacturing Ready - Pre-sorted kits with QR-coded batch tracking
