The Difference Between Brushless and Brushed Motors
FeatureBrushed MotorsBrushless Motors
Efficiency 75-80% (energy loss from friction/sparks) 85-90% (no brush friction)
Lifespan 500-1,000 hrs (brush wear) 10,000+ hrs (no wear parts)
Maintenance Regular brush replacement Virtually maintenance-free
Speed Control Limited by mechanical commutation Precise, high-speed response
Cost Lower initial cost Higher (requires ESC)
3. Key Advantages
Brushed: Simple, cost-effective for low-duty applications (e.g., toys, basic tools).
Brushless: Higher power density, longer lifespan, ideal for drones, EVs, and premium power tools.
4. Real-World Impact
A brushless motor in a drone increases flight time by 20-30% versus brushed.
Industrial brushless systems reduce downtime by 90% due to no brush wear.

About Battery Packs
Differences Between 5C and 10C Power Batteries
1. Discharge Capacity
- 5C Battery: Maximum continuous discharge current = 5× rated capacity
(e.g., A 1000mAh battery can deliver 5A sustained current)
- 10C Battery: Maximum continuous discharge current = 10× rated capacity
(e.g., A 1000mAh battery can deliver 10A sustained current)
2. Typical Applications
Parameter | 5C Battery | 10C Battery |
Common Uses | E-bikes / Low-speed EVs | Racing drones / High-performance RC models |
Runtime | Long-duration (>30 mins) | Short bursts (<15 mins) |
Voltage System | Medium-low voltage (48-72V) | High voltage (>100V) |
3. Key Technical Differences
- Internal Resistance: 10C batteries have ~40% lower resistance
- Cooling Requirements: 10C needs 30% more heat dissipation
- Cycle Life: 5C typically lasts 200+ more cycles
- Cost: 10C batteries are 25-35% more expensive
Selection Guide
✓ Choose 5C When You Need:
- Cost-effective solutions
- Longer cycle life
- Moderate sustained power output
✓ Choose 10C When You Need:
- Instant high-power bursts (e.g., acceleration/takeoff)
- Strict weight limitations
- Frequent charge/discharge cycles

Win-Win Cooperation
Personalized Product Customization & R&D
Focusing on customer and market demands, we deliver targeted product development solutions with high efficiency and quality. Confidentiality agreements are available upon request.
Customized Order Collaboration
We accommodate both small-batch and large-volume customized orders. Typically, mold fees are required for small-batch orders due to high tooling costs. However, these fees can be waived when the order quantity reaches a certain threshold (the exact quantity required for mold fee exemption depends on the structure and weight of the customized product).
Advanced R&D Center
Focuses on analyzing customer and marketdemands. Leading strategic R&D departmentcontributed to advanced outcomes.
