1. At a Glance
Quiet, smooth, and built to outlast the fan it drives.
The YKF-7520 pairs a 100% pure copper winding with ball bearings and a die-cast aluminum shell, then adds the oscillation gearbox inside the motor body. At 35-55W and 1200-1350 RPM it is the motor you specify when the fan is sold on quietness and warranty cost rather than on shelf price.
Customization: voltage, gearbox ratio, sweep angle and shaft on request.
Applications: desk fans, table fans and stand fans with oscillation.
Build: 75x20mm stator, copper winding, ball bearing, aluminum shell.
2. Why Buyers Specify the 7520
Copper Winding: lower resistance means less heat in the winding and steadier airflow as the fan ages.
Ball Bearing: rolling contact instead of an oil film gives lower starting torque, lower drag and no shaft play at end of life.
Aluminum Heat Path: a die-cast shell pulls heat out of the stator far faster than stamped steel, which matters on fans that run all day.
One-Part Oscillation: the gearbox is integrated, so there is no separate bracket, no alignment jig and one less fastener on the line.

5. FAQ
Q: Is a ball bearing worth the price difference over a sleeve bearing?
A: On a fan sold with a multi-year warranty, usually yes. A ball bearing holds shaft position and does not dry out, so the failure mode that drives warranty returns on sleeve bearings is removed.
Q: Can the gearbox be changed for a different sweep angle?
A: Yes. Gearbox ratio and sweep angle are configurable, which lets one motor serve several head designs in the same catalogue.
Q: What is the lead time?
A: 20 days for 1-5,000 pieces and 25 days up to 10,000. Samples ship in 7-10 days.
