Why Small Electric Gear Motors Are a Headache for US Buyers
As a purchasing manager sourcing for automation or robotics in 2026, you're battling relentless pressures. High prices from branded suppliers like Maxon or Portescap eat into your budget – up to $50-100 per unit.
Cheap imports promise savings but deliver low quality: gears strip after 500 hours, motors overheat, causing 37% more failures per IEEE reliability studies.
- Skyrocketing shipping costs from Asia – $15-25/unit to USA ports, plus 4-8 week delays disrupting production.
- No customization: Off-the-shelf ratios don't match your linear actuators or robotic arms.
- Supply chain risks: Competitors' China dependencies lead to shortages, hiking costs by 25% amid tariffs.
- Compliance headaches: Non-UL/CE motors fail FDA or RoHS audits, risking recalls.
These issues slash your ROI. Discover how YIDI fixes them factory-direct.
