Precision Movement and Positioning

  • Automated Test Equipment (ATE): Miniature motors drive probe heads, test fixtures, or robotic arms that move precisely to contact test points on PCBs or semiconductor wafers.
  • Pick‑and‑place systems: Gearmotor combinations provide controlled movement of small components during automated testing or sample preparation.

Actuation in Test Fixtures

  • Clamping and gripping mechanisms: Used in test fixtures to hold samples securely. Miniature motors provide the exact torque needed for consistent clamping force.
  • Rotary or linear actuation: Gearboxes generate higher torque at controlled speeds for actuating switches, connectors, or test stands.

Simulating Real‑World Mechanical Inputs

  • Switch and cable actuation tests: Miniature motors replicate human interaction — pressing buttons, turning knobs, or connecting cables under controlled conditions.
  • Wear and fatigue testing: Motors simulate repetitive mechanical motion to test durability of hinges, sliders, and keypads.
