Product Description

Blower Heating Brushless DC Motor-W8520A


A blower heating motor is a component of a heating system that is responsible for driving the airflow through the ductwork to distribute warm air throughout a space. It is typically found in furnaces, heat pumps, or air conditioning units.The blower heating motor consists of a motor, fan blades, and housing. When the heating system is activated, the motor starts and spins the fan blades, creating a suction force that draws air into the system. The air is then heated by the heating element or heat exchanger and pushed out through the ductwork to warm the desired area.


It is durable for harsh vibration working condition with S1 working duty, stainless steel shaft, and anodizing surface treatment with 1000 hours long life requirement requirements.




Product introduction


The blower heating motor has the following characteristics: The blower's rotor is carefully balanced to ensure smooth operation and minimal vibration. It operates at a higher speed, resulting in smaller gaps between the rotor and the body, reducing leakage and increasing volume efficiency.The impeller runs frictionless, eliminating the need for lubrication and producing oil-free discharged gas, this makes it suitable for applications in the chemical and food industries.The blower operates based on volume, with relatively little change in flow rate with varying pressure. However, the flow rate can be adjusted by changing the speed, allowing for a wide range of pressure options and flow control. Its structure is designed to minimize mechanical friction loss, only the bearing and gear pair have mechanical contact, and the rotor, housing, and gear ring have sufficient strength. This design ensures safe operation and a long service life.


These technical requirements help ensure optimal performance of the blower heating motor, providing efficient and consistent airflow for heating purposes.
