Product Description:
Kollmorgen manufactures the DBL4N00750-B3M-000-S40 as part of its DBL Synchronous Servomotors series. The unit is a brushless servo motor intended for precise velocity and position regulation in industrial automation lines, where it connects to digital drives for coordinated multi-axis motion. Its standard mechanical form allows the motor to be integrated directly into machinery without additional adapters, delivering repeatable torque for pick-and-place tables, small conveyors, and indexing mechanisms. Electronic commutation supports smooth rotation and responsive control throughout repetitive operating cycles.
The motor uses a 105 mm flange that aligns with common gearbox pilot diameters, and its power and feedback lines terminate in keyed connectors for secure cable attachment. Both connectors are angled toward the B-side, reducing the required cable bend radius inside tight enclosures. Motion feedback comes from an integrated encoder, which provides position data to the drive controller for closed-loop motion control. A factory-installed holding brake restrains static loads with 5 Nm of torque when power is removed. The enclosure meets the IP54 protection class, helping prevent harmful dust accumulation and water spray from reaching internal components. Mechanical power passes through a smooth shaft, which supports clamp or friction couplings while avoiding the stress concentration associated with a keyway. The motor has a standard-length housing and a winding intended for a standard-speed operating range.
During normal service, the motor can operate in ambient temperatures from 5 °C to +40 °C. Its varnish and seals tolerate up to 95% relative humidity when condensation is not present. A contact cover on the feedback connector helps block dust from entering around the electrical contacts. The feedback system supports multiturn absolute position tracking, allowing the drive to retain shaft position information across multiple revolutions after an extended loss of power. This capability reduces the need for a separate homing movement when the machine restarts, provided that the connected drive supports the installed feedback interface.
