Brushless Motor Advantages

✅ Zero Carbon Dust

▸ Non-contact design (ASTM F1839 Certified)

▸ Eliminates metal particles from brush wear (ISO 13485 compliant)

✅ Energy Efficiency Revolution

▸ 40% longer runtime* (12V/2600mAh battery, 3h peak torque)

▸ Smart power allocation: Auto-adjusts output for joint replacement/spinal fusion

✅ Precision Surgical Adaptability

▸ Hollow shaft (<7mm bend radius) for 360° narrow-space access

▸ 5-speed presets: Trauma repair/vertebroplasty modes

✅ Zero Maintenance Cost

▸ No brush replacement (Saves $1,200+/year)

Brushless motor: can work continuously for about 20,000 hours, and the normal service life is 7-10 years.

Advantages①：High-purity copper commutator with graphite brushes reduces per-unit cost by 30%. Delivers 4.2N·m initial torque , ideal for cost-conscious surgical units requiring reliable power for sternal saws and basic instruments.

Advantages②：Modular brush assembly allows 5-minute in-surgery replacement by OR staff. With 750-hour maintenance intervals, ensures surgical continuity in resource-limited settings during power fluctuations.

Advantages③：8-24V wide voltage compatibility integrates with 90% existing OR power systems. Dual-brush counterbalance reduces arc erosion to <0.3mm³/h, serving as tactical backup for field hospitals and emergency scenarios.

Shortcoming:

Traditional Brushed Motor Limitations

❌ Efficiency Decay

▸ ≥15% torque drop after 30min (Brush overheating)

❌ Dust Hazard

▸ 0.5-3μm conductive particles (Short-circuit/tissue risks)

❌ Bulky Design

▸ 15% larger size limits hollow shaft engineering

Carbon brush motor: can work continuously for about 5,000 hours, and the normal service life is 2-3 years.
