What is a blower on a motor?

A blower on a motor can refer to two different things: a supercharger in an engine or a blower motor in a vehicle’s HVAC system. A supercharger is a forced induction system that forces more air into the engine, increasing its power. A blower motor in a car is an electric motor that powers a fan, circulating air through the heating and air conditioning system.

1. Supercharger (Blower):

Function: A supercharger forces air into the engine’s cylinders, increasing the air pressure and allowing for more fuel to be burned, thus boosting engine power.
Types: Common types include Roots, centrifugal, and screw superchargers.
Location: Typically mounted on top of the engine, often visible with a prominent “blower” housing.

2. Blower Motor (HVAC):

Function:
The blower motor in a car’s HVAC system is an electric motor that powers a fan which circulates air through the heating and air conditioning system.
Purpose:
It ensures proper ventilation and climate control within the vehicle by pushing air through the vents.
Location:
Typically located under the dashboard, behind the glove compartment, or in the engine compartment, depending on the vehicle.
Resistor:
A resistor is often used to control the speed of the blower motor, allowing for different fan speeds.
