Description
Product Description: YDK-39-6 / YDK-40-6 PSC Condenser Fan Motor The YDK-39-6 (and its closely related YDK-39-6E-6 or YDK-40-6 variants) is a heavy-duty Permanent Split Capacitor (PSC) asynchronous AC motor enclosed inside a fully weather-sealed, black galvanized steel pancake housing. This motor is custom-engineered to withstand intense vibration, rain, dust, and outdoor heat cycles. It sits inside the outdoor condensing unit (ODU) of an air conditioner, driving a large multi-blade axial fan to pull ambient air over the hot condenser coil matrix, releasing heat so the system can continue cooling the indoor living spaces. It features a high-grade pure copper wire winding array and relies on an external run capacitor to smooth out its operational current. Key Technical Features Motor Type: Single-Phase Capacitor-Run Asynchronous AC Motor (6-Pole design). Electrical Inputs: Rated for standard 220V–240V AC at 50Hz/60Hz (current draw sits at roughly 0.33A to 0.39A). Power Output: 39 Watts to 40 Watts continuous mechanical power. Rotational Speed: High-torque, low-noise threshold running at approximately 875 RPM to 900 RPM. Rotation Direction: Often configured as reversible or fixed (CW/CCW) depending on the wiring leads, featuring standard 3-wire or 4-wire termination paths. Wiring & Hardware Compatibility Because of its standardized frame dimensions and multi-hole rear screw-post mounting geometry, the YDK-39-6 serves as a primary universal service standard across the HVAC industry: 1. Outdoor Condensing Units (1.5 Ton to 2 Ton Split ACs) Compatible Hardware: Outdoor units for residential split air conditioners ranging from 12,000 BTU to 18,000 BTU (1.5 Ton to 2 Ton setups) across major brands such as Gree, LG, Trane, Whirlpool, and Midea. Application: Mounts securely to the central wire grid or metal support bracket inside the outdoor chassis box to exhaust heat from the system. 2. High-Voltage Control Contactor Loops Compatible Components: Standard outdoor terminal blocks and dual run capacitors (typically requiring a 2.5μF to 3μF capacitor to stabilize the start phase winding). Application: Wired directly into the main outdoor line terminal alongside the compressor contactor. When the indoor wall unit calls for cooling, the 220V relay triggers both the compressor and this condenser fan motor simultaneously. 3. Direct Cross-Compatible Replacement Families In the global HVAC spare parts trade, this 39W/40W motor profile shares an identical physical blueprint and can be used interchangeably with: Interchangeable Models: YDK-40-6, YDK-39-6E-6, YDK-35-6, and generic 40W 6-pole condenser fan motors featuring a standard 90mm-122mm mounting array.
