Magnetic Circuit TRIZ Cases

A controllable coupling between two planar drive rotors adds coordinated motion modes that a single rotor cannot achieve in automation tasks.

Low-pressure resin injection followed by separate furnace curing fixes motor core magnets without core deformation or injector downtime.

Relative rotor segment rotation adjusts magnetic flux, helping electric tools reach higher light-load speed without flux loss.

Filament arrangement in an FDM bond magnet enables freer ring flux direction and higher surface magnetic flux density.

A resin-side concave and housing-bottom positioning feature prevent stator shift during curing while reducing brake motor axial size.

Non-uniform rotor flux passages and conductive-filled holes suppress magnetic saturation while preserving reluctance torque and manufacturability.

Magnetic coupling replaces external supports in spherical wheel actuation to reduce slip, contamination, and maintenance while improving traction.

Odd-numbered segmented rotor magnets use magnetic repulsion to hold spacing, reducing centrifugal stress and iron core deformation.

Radial recesses, selective magnets, and a hollow shaft improve torque uniformity, torque density, and rotor dynamics in axial flux motors.

Gravity-fed fluid distribution spreads coolant across stator winding heads while a separate reservoir controls oil level and limits transmission splash losses.

A short-pitch flat-wire winding layout cuts harmonic magnetic fields and 6kp noise while allowing flexible odd-layer hairpin connections.

Axial magnetic levitation replaces lubricated thrust bearings in downhole lift shafts, improving reliability in caustic, high-pressure wells.

Combined coils and magnet portions generate rotational and intersecting thrust to shrink maglev motors while preserving contactless rotor attitude control.

Localized busbar thickening suppresses laser penetration at stator coil ends, protecting insulation while maintaining weldability.

Overmolding magnets onto the shaft eliminates harmful glue, simplifies wiper motor rotor assembly, and improves cohesion and air-gap control.

Harmonic-oriented modulation tooth design aligns permeance harmonics and air-gap fields to raise torque density and conversion efficiency.

A heat-dissipating rotor element and gap seal remove heat while blocking contamination, protecting permanent magnets in brushless motors.

Hall sensors on the planar motor mover enable closed-loop multi-axis positioning without friction-prone transmission links or wear.

Overmolding tapered rotor magnets with polymer secures them without adhesives and integrates bearing parts in one lighter molding step.

Higher slit density at the magnet outer surface breaks eddy current paths, cutting motor losses without segmented magnet assembly.

Lubricating oil suspension and magnetic reset replace flexure springs, cutting noise and fatigue while keeping damping stable in vibration motors.
