Motor assemblies from MagnetIQ combine precision magnetics with mechanical robustness. We deliver rotor stacks, magnetic inserts and fully bonded magnet arrangements — ready for integration into electric drives. Whether for high-speed BLDC motors, linear actuators or compact servo systems, our assemblies ensure performance, safety and manufacturability.
Motor Assemblies & Magnet Motor design
What Defines a Motor Assembly?
A motor assembly typically consists of magnets bonded onto a rotating or translating carrier — often with banding, balancing and electrical insulation. The magnetic geometry (surface-mounted, embedded, Halbach) determines the motor performance in terms of torque, speed and efficiency. Precise tolerancing and material compatibility are critical for thermal stability and vibration resistance. In some applications, motor rotors use magnet stacks — permanent magnets built from smaller, electrically insulated segments that are bonded together. This design drastically reduces eddy current losses in high-speed and high-frequency controlled motors.
