Description
The EC frameless DT motors are BLDC motor kits with internal-rotor technology. The rotor and stator are delivered separately, without bearings or motor shaft, and are connected only during assembly. The flat design, the high torques, and a lot of space for cable glands allow a high level of integration into your application.
