Magnetic Circuit Shape/Form/Construction TRIZ Cases
- Three-Axis Voice Coil Motor With Selective Coil Activation
Selective X, Y, and Z coil activation cuts power waste at large rotation angles while improving three-axis response speed and positioning.
- Synchronous Motor Segment Poles Shorter Stator Lamination
Segment poles and a stator core with shorter lamination thickness reduce d-axis inductance, increasing reluctance torque while lowering stator core iron loss.
- Motor Frame Integral Bearing Housing for Rotor Alignment
Integrates a bearing housing protrusion directly into the motor frame, eliminating separate assembly steps and ensuring precise rotor alignment.
- Electric Motor Inner Pole Sleeve SMC Material
Soft magnetic composite inner pole sleeve minimizes magnetic resistance and eddy current losses for efficient high-frequency motor operation.
- Stepping Motor Band Connection for Stator Assembly
A stepping motor uses a band with elastic arms to engage stator and plate connection portions, securing components without welding.
- Segmented Permanent-Magnetic Rotor for Electric Motors
Alternating holder and intermediate rotor sheets reduce short-circuit magnetic flow while maintaining structural stability.
