Wire-free DC brushless motor

The utility model discloses a wire-free DC brushless motor. The wire-free DC brushless motor comprises a fan, a base, pins, a substrate and terminals. The substrate is T-shaped, the edge of the substrate is provided with PIN holes, and the terminals are welded with the PIN holes to form one body through the pins; the substrate is fixedly arranged at the bottom surface of the base; the base is provided with oval radiating holes; and the base is provided with the fan. According to the utility model, the substrate is T-shaped, the terminals are welded with the PIN holes arranged at the edge of the substrate through the pins, the substrate with the terminals is fixed at the bottom surface of the base by use of a motor welding assembly, at the same time, a space is reserved at the bottom surface of the base, and the oval radiating holes are designed, so that a motor coil and the substrate are separated at different areas; and heat dissipation of the motor coil and electronic materials on the substrate is facilitated. The wire-free DC brushless motor reduces the product cost and improves the production efficiency of products; the product performance and reliability are better guaranteed; and the market competitiveness is greatly improved.
