To prevent electrical damage, LG’s fan motor applies a protective resin between the bearing’s outer and inner rings. This layer blocks electric current flow, helping avoid sparking and metal fusion that can lead to serious damage.

What is a Fan BLDC Motor?
A BLDC (Brushless DC) motor is an energy-efficient motor commonly used in HVAC systems. It runs quietly, uses less power, and offers longer-lasting performance.
How is a Fan BLDC Motor different from a traditional motor?
Unlike traditional brushed motors, a Fan BLDC Motor uses electronic control instead of brushes. This reduces noise, increases efficiency, and extends motor lifespan—ideal for modern HVAC systems.
How does a fan motor support stable airflow in HVAC systems?
A reliable fan motor keeps airflow steady, helping regulate indoor temperature, save energy, and improve HVAC performance. LG’s fan motor maintains consistent rotation for efficient air circulation.
