Drum motor: A Quick Guide to Application Scenarios
May 20, 2026| Motorized pulleys are the heart of any conveyor system. Choosing the wrong type leads to inefficiency, rapid wear, or even system failure. The key distinction lies in load capacity, internal drive mechanism, and power.
Light-Duty: High-Speed, Light-Load Handling
Power Range: 20W – 50W (typically 24V/48V DC)
Drive Type: Micro DC motor with O-ring or poly-V belt
Key Feature: Zero-pressure accumulation, low noise (<55dB)
Best For:
Parcel sorting in courier & e-commerce hubs
Assembly lines for electronics or pharmaceuticals
Lightweight tote & carton handling
Carries items like cardboard boxes, poly bags, plastic totes.
Medium-Duty: The Flexible All-Rounder
Power Range: 80W – 100W and above
Drive Type: Enhanced motor, optional chain drive
Key Feature: Supports variable frequency drive (VFD) for speed control
Best For:
Slight inclines (≤15°) & merge/diverge sections
Airport baggage handling (incline segments)
Automated warehouses & medium-weight packaged goods (e.g., beverage cases)
Use this when light-duty units aren't strong enough, but heavy-duty is overkill.
