HVAC motor for shaded-pole applications
The FASCO D205 is a single-phase shaded-pole motor rated at 1/40 hp with a secondary 1/70 hp rating. It runs on 115 V AC at 60 Hz and draws 5 A at full load. The 3.3 frame fits standard HVAC fan and blower assemblies. Continuous duty and automatic thermal protection suit always-on ventilation tasks.
Output headroom and voltage limits
Nameplate speed is 3,000 rpm at 190 W output with a 1.35 service factor providing modest overload margin. Two-speed operation allows basic airflow adjustment. The motor is not usable at 200 V or 208 V, so it must remain on a 115 V supply. Maximum ambient temperature is 40 °C, beyond which thermal protection will trip.
Open drip-proof enclosure and reversible shaft
An open drip-proof design keeps falling moisture out while allowing airflow through the windings. The shaft rotates clockwise or counter-clockwise to match blower-wheel direction. Class B insulation supports the rated continuous duty cycle. Closed-base mounting provides a stable footprint on standard HVAC brackets.

Questions about this item
Will the 3.3 frame motor fit the mounting pattern of my existing 3.3 frame blower housing?
The 3.3 frame designation matches the standard mounting dimensions for that frame size, so it aligns with existing 3.3 frame housings.
How can I confirm the motor is running at the correct 3000 RPM after installation?
Measure the blower output with a tachometer; it should read approximately 3000 RPM under normal 115V 60 Hz supply.
Does the box include a run capacitor or mounting brackets, or must I buy them separately?
The motor is a shaded-pole design with auto thermal protection and does not require a run capacitor; mounting hardware is not included.
