Description
AC Outdoor Fan Motor YDK-35-6 (35W) (widely manufactured by Welling or Changzhou Sun, and utilized heavily by brands like Trane, Chigo, and Quietside). We have left small refrigerator components entirely behind and moved into the heavy-duty ventilation hardware of Residential Split-System Air Conditioners. Here is the accurate product description and its machinery compatibility. Product Description: YDK-35-6 PSC Condenser Fan Motor The YDK-35-6 is a standard Permanent Split Capacitor (PSC) asynchronous AC motor enclosed inside a rugged, weather-sealed galvanized steel pancake housing. This motor is engineered explicitly to operate inside the harsh outdoor condensing unit of an air conditioner. It spins a large multi-blade axial fan to pull ambient outdoor air through the hot condenser coil matrix, forcing thermal energy out of the refrigerant gas so the system can continue cooling the indoor space. It features a dual-bearing structure, an extended single-sided drive shaft (∅8mm diameter, 42mm length), and relies on an external run capacitor to start and maintain smooth rotation speed under high thermal loads. Key Technical Features Motor Type: Single-Phase Capacitor-Run Asynchronous AC Motor (6-Pole configuration). Electrical Inputs: Rated for standard 220V–240V AC at 50Hz/60Hz (115V variants like the standard YDK-35-6 also exist for regional markets, drawing around 0.81A). Mechanical Power Output: 35 Watts continuous output power. Rotational Speed: Operates at a low-noise, high-torque threshold of roughly 850 RPM to 950 RPM. Enclosure Rating: Weatherproof sealed housing designed to withstand direct rain, dust, and high ambient outdoor ambient heat. Wiring & Hardware Compatibility Because it is a standardized industrial motor profile, the YDK-35-6 acts as a universal replacement part across multiple HVAC platforms: 1. Outdoor Condensing Units (9,000 to 12,000 BTU / 1 Ton Minisplits) Compatible Hardware: Outdoor units for residential split air conditioners across major global and regional brands, including Trane, Chigo, Quietside, Fujiaire, and Midea. Application: Mounts directly to the internal steel wire cage or structural top bracket inside the outdoor chassis. It drives the main condenser blade to exhaust heat from the system. 2. Multi-Wire High-Voltage Control Relays Compatible Components: Standard 3-wire or 4-wire high-voltage AC wiring harnesses utilizing an external dual run capacitor (typically requiring a 3μF to 5μF capacitor to stabilize the auxiliary phase winding). Application: Wired directly into the main outdoor terminal block block alongside the compressor contactor. When the indoor wall unit calls for cooling, the outdoor control board sends line voltage to both the compressor starter and this fan motor simultaneously. 3. Direct Cross-Compatible Replacement Families In the global HVAC spare parts industry, this motor configuration can be directly cross-referenced with or swapped out for: Interchangeable Models: YDK-35-6HG, YDK-35-6A, YDK35-6K, Welling YDK35-6, and generic 35W 6-pole condenser fan motors sharing the identical 3-hole or 4-hole rear screw-post mounting geometry.
