The Daikin-McQuay GC5021C has a motor, but a crucial component called motor coupling. While lightweight at 0.84 lbs, it plays a vital role in transferring power within HVAC systems typically operating on voltages between 208-230 volts AC. Here's a motor shaft spinning at high speed (potentially around 950 RPM based on typical HVAC applications) and a pump impeller that needs to rotate at the same speed to move air or water. The motor coupling acts as the bridge between them. It's a small, donut-shaped piece with a hole in the center sized to fit the motor shaft on one end and the pump impeller shaft on the other.

For an efficient and reliable HVAC system, the Daikin-McQuay Motor Coupling » is a great choice for optimal system performance.
