Magnetic Circuit TRIZ Cases

A ceramic sleeve seals cooling fluid around the stator while avoiding conductive sleeve losses and heating in electrical machines.

Stacked hollow disks place magnets near the rim to cut flywheel weight, maintain rotational speed, and improve generator output under load.

Non-magnetic partitions around auxiliary magnets block rotor-core flux short-circuits and raise stator-facing magnetic flux for higher motor output.

Adjustable ferromagnetic rods counteract side loads in a moving magnet motor, reducing rider and cylinder wear without tight alignment tolerances.

Bearings placed at the spindle outlet and a compact brake disc layout enable fast, precise forming with less installation space.

Compression-reset magnetocaloric elements cool rotor magnets at the heat source, limiting eddy-current overheating and demagnetization.

A 12-tooth stator with 10 or 14 pole pairs raises magnetic steel utilization and torque density for high-load wheeled power tools.

A rotating arm and switchable magnet transfer shuttles between linear motor tracks without detach-reattach steps, easing alignment.

Unequal magnet recess end distances raise d-axis inductance in a skewed PMSM rotor, improving flux-weakening control and torque output.

Open V-shaped magnet pockets with chamfered ends and an outer drum raise torque density while supporting high rotor speeds in compact motors.

A centering mandrel and pivoting bearing assembly align the motor to the gearbox shaft, shrinking air gaps, noise, and tolerance sensitivity.

Soft magnetic teeth and a rotor magnet rotate and hold an optical filter wheel without gears, reducing wear and magnetic interference.

Overlapping electromagnetic drive assemblies move an optical element in different directions for autofocus, shake compensation, and compact assembly.

Orthogonal magnet members enable compact two-axis fine stabilization for optical payloads, improving small-angle precision beyond coarse stabilizers.

Magnetic armature and stator assemblies combine linear and rotary displacement in one actuator for precise load application and motion control.

Rotating resin-bath bonding fills rotor magnet gaps evenly, limiting capillary spread, cutting process time, and reducing demagnetization risk.

A radially compressed annular member holds stator and housing position while damping vibration, noise, and stiffness variation.

Bridge portions, magnetic voids, and retention protrusions help a rotor resist centrifugal force while preventing permanent magnet demagnetization.

Adjustable magnetic preload and a ferromagnetic flux shield raise stage stiffness while preserving near-frictionless carrier motion.

Independent urging sections and supply passages clamp multiple rotor cores evenly, limiting plastic leakage and speeding continuous production.

An integrated ring pocket fixes sensor magnets on an external rotor housing with precise alignment, avoiding adhesives and large assembly tolerances.

Setting inverter carrier frequency above a calculated cross frequency cuts eddy current loss across PM rotors and suppression members.

Magnetic attraction replaces a high-force spring to hold rotor axial position, reducing rattling and inertial mass while keeping Hall sensing stable.

Contactless induction or NFC links rotor-mounted sensors to the stator, improving motor temperature monitoring without fragile mechanical connections.

Different coercive-force magnets placed at different rotor depths maintain magnet strength across startup and steady-state temperatures.

Magnetic attraction balances the motor rotor axially to keep sensor gaps stable, cut rattling, and avoid heavy spring-driven inertia.

Axially extended permanent magnets shift softened end edges outside the air gap, cutting magnetic losses without enlarging rotor size.
