Magnet Design Priorities for Hub & Mid-Drive Motors

Hub motors and mid-drive units load magnets differently. We align material, shape, coating and magnetization with rotor diameter, speed, heat and assembly method.

Review My Motor Design
  • Torque Within the Motor Envelope

    Material, geometry and magnetic circuit inputs are reviewed against the torque target and available rotor space.

  • Thermal & Demagnetization Margin

    Grade selection accounts for winding heat, cooling path, duty cycle and demagnetization margin.

  • Rotor Fit, Retention & Balance

    Drawing-based geometry supports adhesive gaps, retention features and rotor balance requirements.

  • Coating for Outdoor Exposure

    Coating selection accounts for road spray, humidity, salt exposure and assembly conditions.

  • Magnetic Consistency

    Flux and magnetization-angle checks support consistent magnetic input across motor builds.
