The impeller, also known as a runner, is a component used in rotating machines such as steam turbines and reaction turbines. It is equipped with multiple blades that receive energy from steam or water and rotate, playing an important role in transferring energy. The impeller installed in a turbocharger typically has 12 to 20 blades arranged radially. The compressor side is usually made of aluminum, while the turbine side is made of heat-resistant alloys. Recently, new materials such as ceramics are also being used.
