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.

Customization:
| Configuration | Typical Applications | Performance Advantages |
|---|
| Bread-Loaf (Rounded Rectangle) | High-torque traction rotors, HVAC compressors | Maximizes magnet volume while preserving mechanical robustness at
the corners; reduces peak flux density on sharp edges, lowering
risk of demagnetization under overload. |
| Perfect Rectangle | Servo and spindle motors where space factor is critical | Simplest machining profile; offers the highest magnet-packing ratio
for maximum torque per axial length. |
| Trapezoidal | Interior-Permanent-Magnet (IPM) rotors, high-speed flywheel
generators | Wider root eases mechanical stress, while narrower crown minimizes
leakage flux—ideal for field-weakening ranges and extended speed
envelopes. |
