XBD-3045 Graphite Brushed DC Motor
Product Introduction
The XBD-3045 is a coreless brushed DC motor with high power density, stability, low wear graphite commutator, powerful neodymium magnets, and high torque features. Its coreless design reduces flux loss, improving the motor's efficiency and power density. Additionally, the use of a graphite commutator gives the motor low wear and high stability, reducing maintenance costs and frequency.The XBD-3045 motor features powerful neodymium, allowing it to generate higher torque and better adapted to high-energy demand scenarios such as drone speed control.
Application
Sinbad coreless motor have a wide range of application such as robots, drones, medical equipment, automobiles, information and communications, power tools, beauty equipment, precision instruments and military industry.
Advantage
The XBD-3045 Graphite Brushed DC Motor has several advantages, including:
1. High power density: The motor has a compact design that provides high power output in relation to its size, making it ideal for applications where space is limited.
2. Low wear graphite commutator: The use of a graphite commutator reduces wear and tear, leading to longer motor life and lower maintenance costs.
3. High stability: The motor's graphite commutator also improves stability and reduces the risk of sparking, which helps to maintain consistent performance over time.
4. Strong neodymium magnets: The motor's magnets are powerful, allowing it to produce high torque and efficiently convert electrical power into mechanical power.
5. High torque: The motor's high torque characteristics make it ideal for high-load starting applications, including robot towing and other heavy-duty tasks.
