Hollow-Cup Motor Blower – Round-to-Rectangular Adapter

1. Structure and Function: Featuring a round‑inlet, rectangular‑outlet adapter design, this component is compatible with hollow‑cup motors, converting circular airflow into a rectangular output. It flexibly accommodates various equipment interfaces, enabling efficient air delivery.

2. Design Optimization: The housing is manufactured via 3D printing in a single piece, with a grille‑style protective structure at the front to safeguard the internal impeller while preventing foreign objects from being drawn in. Its streamlined chamber design reduces aerodynamic drag, enhancing the air‑delivery efficiency of the hollow‑cup motor.

   

3. DIY Application Scenarios: With its compact overall structure, this device is well suited for small hollow‑cup motors, serving as a desktop blower or a miniature cooling fan. It offers an affordable, creative solution for directional airflow, ideal for DIY projects, model building, and similar applications.
