Dayton 4YFF6 Unit Bearing Motor 1/150 hp HVAC Control
Unit bearing motor delivers 1/150 hp at 1,550 RPM for HVAC control applications
- ColorTransparent
- Reliable low-power airflow with 5 W shaded-pole motor
- Consistent 1550 RPM operation at 60 Hz frequency
- Durable cast-aluminium frame resists vibration and corrosion
- Impedance thermal protection prevents overheating at 40 °C ambient
- Versatile horizontal or shaft-up mounting with rear double-foot design
Compact HVAC Motor for Light-Duty Air Handling
The Dayton 4YFF6 is a shaded-pole unit bearing motor rated at 1/150 hp for single-phase 115 V AC systems. It suits technicians and facility staff who need a direct-drive replacement in small ventilation, fan-coil or refrigeration cabinets where a compact totally enclosed air-over design fits the existing mount.
Continuous Operation Within Rated Thermal Limits
Impedance thermal protection and Class A insulation allow the motor to run at its 0.34 A full-load current in ambients up to 40 degrees C without nuisance tripping. The 1.0 service factor means the 5 W output is intended for steady-state duty rather than short overload bursts, so airflow demand should match the nameplate 1,550 RPM rating.
Rear Double-Foot Mount Simplifies Swap-Outs
Cast-aluminium frame and rear double-foot mounting let the unit bolt into horizontal or vertical shaft-up orientations without fabricating brackets. The fixed CCWLE rotation must match the original equipment; installers who overlook the rotation direction are the most common cause of rework.

Questions about this item
How much heat does the 1/150 hp motor generate when running continuously at 1550 RPM?
The shaded-pole motor draws 0.34 A at 115 V AC, producing 5 W output with impedance thermal protection and a maximum ambient temperature of 40 °C.
What power supply and mounting hardware are required to install this unit-bearing motor?
A 115 V AC, 60 Hz single-phase supply is needed, plus bolts for the rear double-foot cast-aluminium frame in horizontal or vertical shaft-up orientation.
Will the CCWLE shaft rotation match the fan blade on my existing HVAC assembly?
The motor rotates counter-clockwise viewed from the lead end; verify your current blade rotation before fitting.
