What actually is an EC motor?

The EC motor is a collector and brushless permanent magnet external rotor direct current motor. The EC controller commutates the motor windings electronically and therefore wear-free. In addition, the EC controller monitors the motor and provides interfaces for easy control of the drive.

EC drives are particularly suitable if the following selection criteria are important:

  • high efficiency even in the partial load range and at reduced speeds
  • wide speed adjustment range, low noise
  • easy commissioning and maintenance-free

Because of these properties, EC motors are very suitable for driving fans that often work in the partial load range and at reduced speeds.

Field of applications

  • Demand-based residential ventilation / central ventilation systems
  • All areas of application for general ventilation technology
  • Applications where minimal energy consumption is required
    (e.g. stable ventilation, greenhouse ventilation)
