Novel design torques up cooling fans

The Tip-Magnetic Driving fan range features a radical new design that sees the position of the fan motor move from its traditional central hub location to the four corners of the unit.

Manufactured by YS Tech, the Tip-Magnetic Driving (TMD) fan range features a radical new design that sees the position of the fan motor move from its traditional central hub location to the four corners of the unit.

Locating the motor at the four corners increases the room available for the motor winding, thus allowing lower power consumption to be achieved.

In a traditional fan motor, the magnetic line of induction has to go through its central metal tube and then to the magnetic poles.

This significantly increases magnetic hysteresis, which in turn reduces torque.

In the TMD motor the magnetic line of induction is directed to the permanent magnet.

This results in low magnetic hysteresis and significantly increased torque.

The TMD fan design reduces the central motor hub area by 75% compared with traditional axial fans.

This increases static pressure and airflow by an impressive 30%.

Not only that, but it also brings the air stream directly to the centralised heat source improving the TMD fan's heat dissipation efficiency by at least 15%.

The new TMD fan is also noticeably quieter.

Rotating fan blades are the main source of noise when a fan is operating.

Unlike standard axial fans, in the TMD fan the motor magnet surrounds the fan blades and it is this "tip-magnetic" design that eliminates the noise of the impeller when it is rotating.
