  1. Product Snapshot
    Cut weight, extend range, and boost torque with Energy Cars’ Best Choice sintered neodymium magnets. Engineered for traction motors, generators, and regenerative braking systems, each magnet is individually oriented to your exact magnetic pattern—radial, axial, Halbach, or skewed—delivering optimal flux distribution in the smallest possible package.
  1. Why EV Engineers Choose Us
• Custom Magnetic Orientation – radial, axial, multi-pole, Halbach, or skewed to reduce cogging.
• EV-Grade Grades – N35SH–N54EH, 150 °C continuous operation.
• ±0.05 mm Tolerance – press-fit into laminated rotors, zero balance correction.
• IATF 16949 Plant – full PPAP, CPK ≥1.67, traceable lot codes.
• Energy Savings – up to 8 % higher motor efficiency vs. standard orientation.
• 7-Day Prototypes – 3-D printed tooling, fast sintering, global delivery.
