With Integrated Controller

Brushless DC motors (short: BLDC for brushless DC, also called EC motors) are designed like a three-phase synchronous machine with excitation by permanent magnets.

The three-phase winding is driven by a suitable circuit in such a way that it generates a rotating magnetic field which pulls the permanently excited rotor along with it.

EC motors of Dunkermotoren are commutated and controlled by a mostly integrated electronic to which a DC direct voltage is applied. BLDC motors are also similar to classic DC motors in their overload behaviour.

Brushed DC motors from Dunkermotoren are robust, cost-efficient and easy to commission. Due to the wear of the carbon brushes, their service life is limited. Depending on the design and application, the service life is typically between 1000 and 8000 hours.

Brushless DC motors, also known as EC motors, are electronically commutated and have a significantly longer service life and lower interference radiation due to not having carbon brushes. The service life is usually limited by the ball bearings and is several 10000 hours, depending on the application. In addition, the motors have an even higher power density and dynamics, easy to implement protective functions and very good controllability.
