Product Description:

The DBL3H00250-B3M-000-S40 is a brushless servo motor produced by Kollmorgen as part of its DBL Synchronous Servomotors series. This standard-length unit converts commanded electrical input into tightly controlled rotary motion for axes that demand repeatable speed and position in industrial automation environments such as packaging stations or small-frame gantries. It is intended for closed-loop motion systems where stable rotation, accurate positioning, and consistent response are important during repeated production cycles.

The motor has a square mounting interface with a 75 mm flange, allowing interchange with compact gearheads without adapter plates. Continuous stall torque reaches 2.5 Nm, and the rotor is equipped with a holding brake so the shaft can remain secured when drive power is removed. Electrical power and feedback are routed through sealed industrial connectors, and the feedback socket includes contact protection to reduce contamination. Overall enclosure sealing meets IP54, so the housing resists limited dust and water spray while remaining compact and fanless. All connectors are angled toward the B-side of the housing, which simplifies cable routing along machine frames. A smooth shaft supports clamp-style couplings and helps reduce fretting wear during rapid reversals.

The motor operates in ambient temperatures from 5 to 40 °C and continues to function at up to 95% relative humidity without condensation. Position feedback is provided by a multi-turn encoder, so the control system retains absolute shaft position across power cycles. The stator uses the high-speed winding variant, which supports elevated base speed while staying within the allowed thermal range. This arrangement is useful for applications that need repeatable startup position and stable motion after brief power interruptions. The standard option package does not add extra coating or sealing features.
