AC Ind Motor YDKS-18-4 18W

Description

Based on the search results on your screen, you are looking at the YDKS-18-4 (also frequently listed as YDK-18-4) Air Conditioner Indoor Blower Motor. Item Description The YDKS-18-4 is an OEM-standard, single-phase Asynchronous AC Induction Fan Motor (18W). It is specifically designed as a replacement part for the indoor wall-mounted evaporator unit (inner machine) of standard mini-split air conditioning systems. Unlike the high-voltage DC motors found in full-inverter systems, this is a classic AC-powered motor running on standard mains voltage. It features a robust multi-wire setup to facilitate mechanical tap speed regulation (High/Medium/Low fan speeds) or PG feedback control via your air conditioner’s main PCB. Technical Specifications Model Series: YDKS-18-4 / YDK-18-4 / YKFG-25-4-121 Motor Type: Single-Phase AC Induction Motor / Asynchronous Power Output: 18W Operating Voltage: 220V−240V (or 100V−130V for regional specific variations) Frequency: 50/60 Hz Rated Current: 0.18A to 0.2A Poles: 4P Speed: ~ 1300 to 1350 r/min (RPM) Capacitor Requirement: Typically requires an external 1.2μF capacitor (often built onto the AC control board) Compatible Brands & Systems The 18W 4-Pole AC motor framework is one of the most widely cloned architectures in the HVAC industry. It is primarily built for 9,000 BTU to 12,000 BTU (0.75 to 1.0 Ton) non-inverter or fixed-speed split air conditioners. 1. Brand Compatibility This specific motor design is universally adapted by a massive array of global HVAC manufacturers, including: Midea (Commonly uses the YKFG-25-4-121 variant) Gree Trane (Particularly for wall-mounted units under part code TW518-005 / MCW518ZBOOOA) Daikin (Interchanges with series YYW18-4-5018) Chigo (Zhigao) Videocon Carrier 2. Cross-Reference Part Numbers If your old indoor blower motor features any of the following alternate factory codes, the HEXEH YDKS-18-4 or generic equivalents are typically a direct match: YKFG-25-4-121 YKFG-28-4-3 YYW18-4-5018 TW518-005 Essential Replacement Checklist: Because AC indoor motors use different wiring layouts, verify if your original layout uses a PG feedback plug (a separate small 3-wire plug alongside the main power lines) or a 3-speed tap wire harness. Make sure to wire according to the circuit diagram sticker printed directly on the new motor shell rather than matching the old wire colors blindly.
