Structural type: Cantilevered, the transmission structure that connects the main shaft of the fan and the motor with a coupling. The coupling is installed on the outside of the two bearing seats, and the fan's speed is the same as the motor's speed.
Advantages: The mechanical efficiency is higher compared to the C-type drive.
Disadvantages: High precision requirements for installation and maintenance.
Main application: Suitable for medium-sized and above fans, widely used."
