In modern vehicles, the blower motor (Blower Motor) is an essential component of the air conditioning and heating systems. It is responsible for pushing air through the heater core or evaporator to regulate the temperature inside the cabin.
A blower motor is a small electric motor typically installed below the dashboard or behind the glove compartment. Its primary task is to drive the fan blades to promote airflow. This motor can be a brushed DC motor (used in older models) or a brushless DC motor (widely used in newer models), the latter being more efficient and requiring less maintenance.
When you turn on the car's air conditioning or heating system, the blower motor circuit sends a signal, usually via a relay and control module, to draw power from the car battery. The motor activates and begins to rotate, with its shaft passing through a circular wheel (called the blower motor fan or cage). As the motor rotates, it draws air in and pushes it through the HVAC system's ducts. Depending on the climate control operation required, the fan directs the air through the heater core or evaporator. If the air passes through the heater, the temperature rises; if it passes through the evaporator, the temperature drops, eventually exiting through the air vents into the cabin.
| Function | Description |
|---|---|
| Air Circulation | Helps achieve air circulation through the air conditioning or heating system, ensuring that the cabin temperature remains within a comfortable range. |
| Temperature Regulation | Effectively lowers the interior temperature when working with the air conditioner; in winter, it raises the temperature by passing through the heater core. |
| Air Purification | When used with an air filter, the blower motor can also help filter the air entering the cabin, reducing dust and other pollutants and improving air quality. |
| Defrosting and Demisting | Helps clear frost or fog from the windshield, ensuring clear driver visibility and enhancing driving safety. |
| Multi-Speed Adjustment | Modern blower motors typically have multiple speed settings, allowing users to adjust the airflow volume according to different climatic conditions and personal preferences. |
| Low Noise Design | To provide a comfortable driving experience, many new models feature silent technology to reduce noise levels during operation. |
