In the following chart, you will find the first 3 Centrifugal Fans coming with a shaded pole motor which are CY063, CYZ076 or CYZ100, small models can adopts Shaded Pole Motor because at very low power (13W–40W), the inefficiency doesn't waste much absolute energy, and it keeps the price low. Larger Models CY076, CY100, CY125, CY127, CY129, CY150, CY180, CY200 are with Asynchronous Motor for higher efficiency.
CY076, CY100 once you get to larger fans, a shaded pole motor would generate too much waste heat. Therefore, they switch to Asynchronous Motor (Capacitor) to handle the higher load efficiently.
Based on the product specifications for the centrifugal blower fans (typically manufactured by Cam York and sold by RobotDigg), the A and B direction options refer to the rotation direction of the impeller and the corresponding air outlet orientation.
A Direction (Type A): Typically refers to Clockwise (CW) rotation. When viewing the fan from the motor side, the impeller spins clockwise, and the air outlet is usually oriented to the Right (Right Hand Discharge).
B Direction (Type B): Typically refers to Counter-Clockwise (CCW) rotation. When viewing the fan from the motor side, the impeller spins counter-clockwise, and the air outlet is usually oriented to the Left (Left Hand Discharge).
Key Differences:
Airflow Exit: The direction determines which way the air is expelled (straight, left, or right) relative to the mounting flange.
Installation: You must choose the option that matches your mounting requirements (e.g., if you need the air to blow out the left side or right side of the machine).
Note: Many listing descriptions for the CY series (like the CY100B) explicitly link "B" to "CCW" rotation.
Recommendation: Check the product images or the technical drawing "chart" mentioned on the RobotDigg page. Look for the arrow on the fan housing; if it points clockwise, it is Type A (or standard); if counter-clockwise, it is Type B. If you are replacing an existing fan, match the outlet position and rotation arrow of your old unit.
