1. At a Glance
Small blade, real airflow - 2400 RPM in a nine-inch package.
A 9-inch blade cannot move air the way a 16-inch blade does, so compact fans have to run fast instead. The YKHF-6612 is a 2-pole, 45W motor at 2400 RPM, delivered as an assembly with bracket, oscillation sync motor, hinge and plastic parts - one part number instead of five.
Customization: voltage, stator size, shaft and blade fixing on request.
Applications: 9-inch table fans, desk fans and small office cooling units.
Design: dual shaft, 5-wire 3-speed control.
2. Why 9-Inch Fans Need This Motor
Speed Where It Counts: 2400 RPM is roughly double a standard table-fan motor, which is what gives a compact fan a usable throw of air.
Dual Shaft: the front shaft drives the blade and the rear shaft drives the oscillation link through a brass bushing, so blade and sweep run from one motor.
An Assembly, Not a Bare Motor: bracket, sync motor, hinge and moulded parts ship as a set, removing inbound part numbers and alignment work.
Vibration Control: flange mounting keeps the shaft axis parallel to the blade plane - essential at twice the usual speed.

4. Deep Customization & OEM Services
Stack length: a longer stack trades a little top speed for torque and lower noise.
Winding: aluminum, copper-clad aluminum or 100% copper.
Shaft and fixing: diameter, thread, nut or circlip to match your blade hub.

5. FAQ
Q: Does the assembly include the oscillation motor?
A: Yes - the sync motor for head sweep is part of the assembly, together with the bracket, and hinge.
Q: Do I need to add a capacitor?
A: The motor is supplied for capacitor-free or flexible matching. Tell us the circuit on your switch plate and we confirm the value to use.
Q: Is 2400 RPM noisy?
A: Speed amplifies an unbalanced blade, not a good one. Send the blade weight and balance grade - on a balanced blade this motor runs smoothly and quietly.
