Magnetic Circuit TRIZ Cases

Accommodation holes built into spaced rotor-frame ribs hold balance weights against centrifugal force, preserving motor balance in operation.

Interlocking rotor slots and overmolded plastic retain inset magnets without fasteners, cutting assembly steps while preserving air-gap efficiency.

Aligned magnetic powder in anisotropic filaments raises radial surface flux density in ring-shaped bond magnets.

A segmented magnetic steel slot layout packs more rotor magnets to raise q-axis inductance, cut torque ripple, and resist demagnetization.

Pre-grouping magnets with opposite force directions simplifies Halbach rotor assembly while preserving array configuration precision.

A bent lead extension on the image sensor substrate simplifies spring assembly while supporting stable OIS and autofocus motion with lower noise.

Curved grooves at key rotor slot ends reshape magnetic flux barriers to cut torque ripple and improve machine stability.

A narrowed terminal lamination recess stops rotor magnets from slipping during vertical assembly while still allowing potting compound flow and air escape.

Inclined lightening holes in an embedded magnet rotor cut inertia and reshape magnetic flux to speed torque response without major torque loss.

Separate planar motor chambers move substrates without exposing the transfer module to motor dust, helping maintain high vacuum and precise handling.

A bearing-linked stator and rotor assembly shortens the tolerance chain to maintain precise air gaps in yokeless axial flux machines.

Brazing the laminate to the axial flux rotor body improves join strength under heat and speed while preserving isolation to limit eddy currents.

By leading both winding ends from one coil and equalizing conductor portions, this case shrinks stator parts while reducing motor vibration and noise.

Pre-coated air bearing sleeves avoid shrink-fit heat damage on the rotary shaft, preserving wear resistance in electric compressor rotors.

A narrowed rotor-slot slit with exposed lamination surfaces improves die-cast rotor cooling while limiting skin-effect current concentration and loss.

Stored die positions let different rotor core thicknesses be clamped accurately without master workpieces, simplifying plastic filling.

A spring-sheet stage rotated by coil-magnet force enables compact 3D sensing with precise optical scanning and lower system complexity.

A shared self-bearing motor and magnetic bearing layout cuts bearing count, saves space, and raises flywheel energy storage density.
