Fan assembly for an hvac system

A fan assembly for a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:

• a hub having a rotational axis and a fan blade extending from the hub;
• a motor shaft coupled to the hub and configured to drive rotation of the hub about the rotational axis;
• a fan pitch adjuster disposed about the motor shaft and configured to engage with the fan blade to adjust a pitch of the fan blade relative to the hub in response to movement of the fan pitch adjuster along the motor shaft;
• and
• an actuator coupled to the fan pitch adjuster and configured to drive the fan pitch adjuster along the motor shaft to adjust the pitch of the fan blade.

A fan assembly for a heating, ventilation, and/or air conditioning (HVAC) unit, comprising:

• a hub;
• a fan blade rotationally coupled to the hub and extending from a rotational axis of the hub;
• a motor shaft coupled to the hub and configured to drive rotation of the hub about the rotational axis;
• a fan pitch adjuster engaged with the fan blade and configured to translate along the motor shaft, wherein the fan pitch adjuster is configured to rotate the fan blade relative to the hub in response to movement of the fan pitch adjuster along the motor shaft such that a pitch of the fan blade is adjusted;
• and
• an actuator coupled to the fan pitch adjuster and configured to induce the movement of the fan pitch adjuster along the motor shaft.
