Magnetic Circuit TRIZ Cases

Stacked magnetic drive circuits reduce plane area while a thickened third yoke prevents saturation and suppresses thickness growth.

A planar stage moving apparatus uses four linear motors and an air bearing unit to drive a table.

Segmented winding elements with reversal sections enable radial airflow through stator overhangs, reducing interconnection points and simplifying assembly.

Mechanically coupling hydraulic and rotary sections on a shared shaft reduces inertia and backlash for high dynamic test bench performance.

A casting compound transmits mechanical forces into the stator of an external rotor motor.

A BLDC motor rotor incorporates a non-magnetic barrier to block leakage magnetic flux between permanent magnets.

Figure 8-shaped linked coils reduce crossover lines and production steps, resolving automation challenges in complex fractional slot motor manufacturing.

Peening electrical steel core cut edges removes residual stresses from punching, reducing core losses and tuning magnetic permeability.

Segmented coil units in a hollow cup winding improve conductor utilization, reducing distribution coefficients and boosting motor power intensity.

Polygonal spiral conductive traces fill spaces between adjacent windings to eliminate non-effective areas and improve electromagnetic performance.

Mixed clockwise and counter-clockwise winding directions in the stator coil balance phase draw-out resistance, reducing power imbalance and torque ripple.

Segmented stator elements absorb braking forces into the foundation, eliminating heavy gears and mechanical conversion losses.

An axial vent hole in a motor support frame separates tubular parts, preventing stator heat from reaching the bearing member.

A dual-axis planar motor uses a coil bracket positioned within a magnet gap to drive orthogonal movement along two axes simultaneously.

Adhesive joints and radial bracing secure permanent magnets on the rotor hub, eliminating bulky interlocking structures that limit magnetic volume fraction.

A rotary electric machine case uses a protrusion portion to separate the bearing from the rotor core.

Vertical guide structures suspend chains from gravity to eliminate stator abrasion and maintain movement accuracy.
