High-Efficiency Brushless Drone Motors LN4730D24-001 - China Suppliers and Factory for UAV Solutions

This silent external rotor brushless DC motor is specially designed for three-axis stabilizer gimbals. It adopts high-performance brushless technology and features ultra-low noise, high-precision control and smooth operation. It is suitable for professional photography, film and television shooting, drone gimbals and other scenarios, ensuring the stable and smooth operation of the equipment and facilitating the shooting of jitter-free high-definition images.

• Ultra-Low Noise (<25dB): Optimized magnetic circuit design and precisely balanced rotor keep operating noise below 25dB, preventing motor noise from interfering with on-site recording.
• High-Precision Stabilization (±0.01°): High-resolution encoder support with precise angle feedback. Low rotational speed fluctuation (<1%) ensures smooth shooting images.
• High Torque Density: External rotor structure directly drives the gimbal shaft, reduces transmission loss, responds faster, and supports heavy loads of 500g–2kg.
• Long Lifespan (>10,000 Hours): Brushless and carbon-free brush wear design with Japanese NSK precision bearings, suitable for long-term continuous operation.
• Lightweight Aluminum Alloy Shell: Aviation-grade aluminum alloy ensures portability. Modular design supports quick installation and is compatible with mainstream three-axis stabilizer systems.
• Built-in Temperature Sensor: Efficient heat dissipation structure ensures no thermal slowdown during long-term operation, suitable for outdoor high-temperature environments.

• 1. What are your prices?
  Our prices are subject to specification depending on technical requirements. We will make an offer once we clearly understand your working condition and technical requirements.
• 2. Do you have a minimum order quantity?
  Yes, we require all international orders to have an ongoing minimum order quantity. Normally 1000PCS; however, we also accept custom-made orders with smaller quantities at a higher expense.
• 3. Can you supply the relevant documentation?
  Yes, we can provide most documentation including Certificates of Analysis / Conformance, Insurance, Origin, and other export documents where required.
• 4. What is the average lead time?
  For samples, the lead time is about 14 days. For mass production, the lead time is 30–45 days after receiving the deposit payment. Lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products. In all cases, we will try to accommodate your needs.
• 5. What kinds of payment methods do you accept?
  You can make the payment to our bank account, Western Union or PayPal: 30% deposit in advance, 70% balance before shipment.
• 6. Is this motor compatible with professional cameras and mirrorless cameras?
  Yes, the external rotor structure supports heavy loads and is fully compatible with professional cameras, mirrorless cameras, and other devices, stably carrying a weight of 500g to 2kg on three-axis stabilizer gimbals.
