VARIODRIVE Compact-Motor VDC-3-54.14 – – – – – – – 3-phase external rotor motor in EC technology. Dynamically balanced rotor with 4-pole, plastic-bonded ferrite magnet. Integrated operating electronics with powerful microcontroller. Excellent control response due to digital 4-Q PI controller. High operating efficiency due to FET power stage. Analogue set value. Operating mode selection (direction of rotation, braking and motor enable) via 2 control inputs. – Protection against overload due to integrated, speed-dependent current limiting. – Customer-specific version possible based on software and hardware adaption (e.g. fixed speed, direction of rotation).
