32mm Outer Rotor Brushless DC Motor

32mm Compact Size Brushless DC Motor

Features: high quality, high precision

Applications: robot, coffee machine

 

 

Key Advantages of the Outer Rotor Design:

Compact & Flat Profile: The outer rotor architecture enables an extremely low axial height and space-saving form factor, making it an ideal solution for applications with strict restrictions on installation space and thickness.

High Torque Density: By utilizing the outer shell as the rotating component for direct torque output, this design achieves a higher torque density within the same volume, providing superior power for direct-drive applications requiring high torque.

Smooth Operation & Enhanced Cooling: The rotating outer casing acts as an effective heat sink, significantly increasing the surface area for improved thermal dissipation. This design also contributes to excellent dynamic balance, ensuring remarkably smooth and quiet performance.

High Quality: Manufactured with premium materials for durability and long-term reliability.

High Precision: Ensures accurate control and consistent performance for demanding tasks.

Ideal For: Robotics, coffee machines, and other applications requiring a reliable micro motor.
