McQuay Daikin 669498001 Motor

The McQuay Daikin 669498001 motor is a high-performance 115V direct drive blower motor designed specifically for integration within Daikin and McQuay air handling units and fan coil systems. Engineering for reliability in demanding commercial and residential HVACR environments, this 1/4 HP replacement motor operates at a synchronous speed of 1075 RPM. As a 3-speed HVAC motor, it provides the versatile airflow control necessary to maintain precise static pressure and CFM requirements across various heating and cooling stages. This Permanent Split Capacitor (PSC) motor features a standard NEMA frame configuration, ensuring a direct fit for OEM McQuay fan coil parts without the need for mounting modifications or bracket fabrication in the field.

For service technicians and mechanical contractors, the 669498001 offers a robust solution for restoring system efficiency. The multi-speed taps allow for fine-tuning the indoor blower assembly to match original equipment specifications, promoting consistent air exchange and reducing component stress. Built with high-grade copper windings and thermal overload protection, this motor is a critical Daikin HVAC spare part for maintaining uptime in critical climate control applications.

Common Questions

Each lead wire is color-coded to indicate High, Medium, and Low speeds. Refer to the system's original wiring diagram or the motor nameplate to ensure correct termination with the fan relay or control board.

Yes, as a Permanent Split Capacitor motor, it requires a specific MFD-rated run capacitor to achieve optimal starting torque and operating efficiency. Check the motor housing for the required microfarad rating.

This motor is primarily utilized in Daikin Applied and McQuay fan coil units (FCUs), packaged terminal air conditioners (PTACs), and small air handlers requiring a 1/4 HP 115V drive.
