Smaller, Swifter, Stronger

By evolving from surface-mounted to interior magnets—first bar, then arc types—LG’s rotor structure has increased magnetic flux by 75% and reduced volume by 46%. This advancement supports the development of more compact and efficient fan motors.

Smooth & Quiet Operation

LG’s arc-type rotor with 10 poles helps the fan motor run more smoothly and quietly by reducing magnetic resistance. It also uses 180° conduction control to lower vibration and noise during operation.

Electrical Damage Prevention

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.

FAQs

Q. What is a Fan BLDC Motor?: A.
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.

Q. How is a Fan BLDC Motor different from a traditional motor?: A.
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.

Q. How does a fan motor support stable airflow in HVAC systems?: A.
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.
