Ventilation channels built into the coupling member drive gas through the rotor to cool the stator in compact high-speed rotating machines.

An arc-shaped shaft transition and gap-forming holder reduce press-fit load spikes, preventing burrs and eliminating deburring.

Upper and lower housings with lugs, holding portions, and blockers improve ceiling fan motor support while keeping air and dust out.

A dismantlable sealed coreless stator uses hermetic connectors and oil recirculation to block gas ingress and sustain generator efficiency.

An embedded shaft slipring and brush layout shortens exciter power transfer, separates wet and dry zones, and reduces wear and friction losses.

Metal cutout features replace the resin coil holder to align the coil precisely, enabling a larger coil and stronger vibration in a compact actuator.

An embedded magnetic rail and outer-side guide rail reduce base deformation, noise, and electrical corrosion in compact linear motor modules.

A mounting seat stabilizes the position feedback member on the output shaft, improving sensor detection and brush head oscillation control.

A gas spring stores expansion energy so a free-piston engine can drive the next stroke while a linear machine generates electricity with lower losses.

A spigot-jointed rotor shaft uses one bearing, elastic cushioning, and grease to cut friction, simplify support, and reduce wear.

A sun gear and multiple planetary gears synchronize several toy execution units from one motor, improving motion accuracy while cutting linkage complexity and cost.

A rigid PTO-RPS assembly with bearing constraint minimizes radial misalignment, preserving accurate rotor position sensing under vibration and thermal shift.

An elastomeric damping ring in the annular channel isolates ring gear vibration from the housing, cutting EV gearbox NVH without added covers.

A shaft shoulder, locking screw, and bearing retainer let one bearing carry both thrust and tensile loads, cutting aircraft weight and complexity.

Wheel sprockets and chain-driven generators turn vehicle motion into electricity for EV charging or grid supply while keeping the generator layout modular.

A one-piece shaft and drive gear replaces bulky spline joints to cut motor size and weight while preserving torque and smooth rotation.

A nutating rotor and dynamic air gap turn radial magnetic pressure into smooth high-torque transmission while avoiding stator-rotor contact.

Direct gear engagement between the motor shaft and spindle drive cuts intermediate gears, saving space and improving steering column adjustment efficiency.

A unidirectional clutch lets a flat microgenerator keep the rotor spinning after one movement, improving voltage generation in compact devices.

DC-field rotor alignment enables keyless resolver press-fitting, reducing tolerance chain errors and improving angular sensing accuracy.

A hollow shaft with an internal Halbach magnet array boosts linear motor power density while simplifying stator assembly and coil connections.

An auxiliary rotor and flux regulator stabilize dual rotors, reduce axial oscillations, and improve magnetic flux control accuracy.

A coaxial hollow output shaft with axially adjacent one-way clutches saves space, simplifies assembly, and supports torque measurement.

Separate stator coil groups remove the neutral bus bar, cutting weight, installation effort, circulating currents, and resistive losses.

An axial motor directly coupled to the treadmill cylinder cuts bulk and kinematic wear while delivering efficient low-speed belt drive.

A shared bearing support aligns the rotation shaft and sun gear centers independent of housing molding accuracy, improving force transmission and reducing noise.
