EC fans and motors - ebm-papst A&NZ

Simon talks about EC fans and motors. He presents an EC axial fan that is typically used in refrigeration condensers and chillers for cooling buildings. The fan is made up of the EC motor and the impeller, mounted on the external rotor of the motor. An EC motor is a permanent magnet motor with on-board electronics. Using the example of a mixed-flow fan, Simon shows the components of a typical EC fan: impeller, motor and electronics. Similar to a DC motor, an EC motor has a range of north and south poles inside. The electronics control the power and speed of the motor. Permanent magnet EC motors are of comparatively higher efficiency than AC motors. They are typically rated IE4, the highest rating available for motor technology.
