D283-3A(28mm)
I.CH
Square
This 28mm DC planetary gear motor integrates precision gear design with stable DC drive technology, delivering high torque density, smooth operation and low noise. Featuring robust construction and reliable performance, it supports flexible forward/reverse rotation and long service life. Ideal for smart devices, robotics, automation equipment, precision instruments and automotive components, it ensures consistent power output and stable motion control for compact, high‑demand applications. This 28mm planetary gear motor fits water‑sampling instrument with silicone tube squeezing actuation. The all‑metal gear resists static rebound stress. Custom D‑flat shaft prevents coupling slip. High reduction ratio improves anti‑back‑driving performance after power‑off. We provide mechanical drawings, sample & mass‑production quotations for your equipment validation

FAQS:
1. Q: Why propose a slightly different gear-ratio instead of my preferred window?
A: Multi-stage planetary ratios are discrete; the closest manufacturable ratio is selected and confirmed via drawings before sample preparation.
2. Q: Which shaft detail matters most for tube-squeezing mechanisms?
A: Output-shaft diameter plus flat-cut D-shape; this prevents coupling slip when transmitting torque to the tube-compressing cam/roller.
3. Q: Should we share existing motor reference data with the new supplier?
A: Yes—field experience from incumbent motors helps the supplier narrow feasible paths, shorten sample development and avoid mis-specification.
4. Q: Can one quotation cover both sample and mass-production pricing?
A: Yes—request a combined quote for sample batch plus annual volume to separate prototype cost vs. mass-production unit pricing; technical drawings usually accompany the quotation.
5. Q: Standard confirmation workflow before sample manufacturing?
A: Review drawing dimensions, gear material and pricing, then send formal written approval; sample production and shipment start only after that.
