Tip-Magnetic Driving (TMD) is a fan technology invented by Yen Sun Technology Corporation (also known as Y.S. Tech).
Tip-Magnetic Driving moves the motor out of the hub of the fan and puts it around the edge. The impeller blades are surrounded by a ring studded of twelve magnets which are acted upon by four coils located in the corners of the frame.
The design of a TMD fan reduces approximately 75% of the motor hub area of a traditional fan.
Fan design relocates brushless DC motor into the housing. (Special Section: Cooling Devices & Thermal Management).
