Overview
This listing is for one YDK-185-6A19 single-phase PSC AC motor rated 1/4 HP, 208–230 VAC, 60 Hz, 1.4 A, and 1100 RPM. The motor is thermally protected and uses a run capacitor. A loose 6 µF 370 VAC capacitor is included, but the motor nameplate specifies a 5 µF 450 VAC capacitor for proper operation.
R&P Service Insight
PSC motors are capacitor-sensitive. The capacitor value should match the motor nameplate rather than relying only on what was found with the motor.
- Correct Nameplate Value: 5 µF / 450 VAC.
- Included Loose Capacitor: 6 µF / 370 VAC.
- Install Check: Confirm wiring, rotation, mounting, shaft, and capacitor rating before use.
R&P Knowledge Hub
Compatibility: Verify before ordering. Match the YDK-185-6A19 model, electrical rating, RPM, rotation, mounting, shaft, and capacitor requirement.
Vehicle / System Fit: Commonly used in compatible exhaust fan, ventilation, blower, air handler, evaporative cooler, and industrial ventilation style equipment.
Installation Notes: Wiring shown for PSC arrangement: brown to capacitor, yellow to line through capacitor, black to line, and green/yellow to ground.
Performance Insight: A higher-than-specified capacitance value can increase auxiliary winding current, reduce efficiency, increase heat, and shorten motor life.
Brand & Fitment Note
Selling Brand: R&P Carriages inventory item; motor manufacturer brand is not specified from the provided nameplate details.
Application Reference: Equipment types listed are general application references only and do not guarantee fitment.
What This Means: This listing is for a YDK-185-6A19 replacement-style PSC motor, not a guaranteed OEM-branded item.
Before Ordering: Verify model, voltage, RPM, rotation, capacitor rating, shaft, mounting, wiring, and included components.
R&P Repair Insight
The loose capacitor should not be assumed correct for this motor. Follow the motor nameplate requirement when replacing or installing the run capacitor.
- Capacitor Value: Motor nameplate specifies 5 µF.
- Voltage Rating: Motor nameplate specifies 450 VAC.
- Fit Check: Confirm physical mounting, shaft dimensions, rotation arrow, and wiring before installation.
