Product Description:

The DBL3H00250-QR2-000-S40 is a brushless servo motor manufactured by Kollmorgen for the DBL Synchronous Servomotors series. Designed for closed-loop positioning and velocity tasks in automated machinery, the unit converts electrical power from a matched drive into precisely controlled mechanical torque for axes that require repeatable motion and fast cycle changes. In multi-axis gantries, picking stages, or compact joints, the motor supports highly dynamic duty cycles while maintaining accuracy through integrated position feedback.

The mechanical interface uses a 75 mm square flange that aligns with IEC patterns and includes a smooth shaft for direct coupling to gearboxes or pulleys without keys. The stator has a high-speed winding that permits operation at an elevated base frequency. The motor uses a two-pole configuration, which supports low inertia and quick torque response. Position data are returned through a resolver, a passive sensor that tolerates electrically noisy environments and sends absolute angular information to the drive. Power, feedback, and thermal leads exit through connectors mounted on the housing. These connectors are angled toward the B-side of the motor to provide accessible cable routing. The frame has a standard length profile that supports installation in compact machine assemblies.

The permitted ambient temperature ranges from 5 to +40 °C, allowing the motor to operate in many cabinet-free machine spaces without derating. Sealed joints and gaskets provide an IP54 protection rating, which guards the enclosure against limited dust ingress and splashing water. An additional spring-loaded contact at the feedback connector helps protect the pin array from stray metal chips. Coatings and potting compounds withstand up to 95% relative humidity, making the unit suitable for humid factory areas. The materials and windings follow the series standard option code, while the angled connector orientation helps keep the connector faces away from direct washdown spray.
