Salient Poles TRIZ Cases
- Magnetic Iris Module for Three-Step Camera Aperture Control
A three-pole magnet iris enables three precise aperture sizes in compact camera modules while avoiding added weight and autofocus interference.
- Electromagnet Tooth Recesses to Cut Friction in Magnetic Conveyors
Recessed electromagnet teeth lower suction-driven friction in magnetic conveying, reducing surface wear and current loss.
- Linear Motor Armature Teeth Asymmetry for Cogging Force Reduction
Varying end tooth dimensions creates opposing cogging components that cancel out, improving positioning precision without increasing armature length.
- Stepped Electromagnetic Drive Pole Structure for Torque and Speed
A stepped rotor and stator pole design increases magnetic overlap area to enhance reluctance torque in compact electromagnetic drive mechanisms.
