Product Description:

The DBL4N00750-03S-00K-S40 is a brushless servo motor produced by Kollmorgen and assigned to the DBL Synchronous Servomotors series. This motor is built for closed-loop position and speed control in industrial automation, where tight motion profiles are required for assembly, packaging, and material-handling axes. Its brushless design supports repeatable motion on axes that must respond accurately to changing loads and frequent speed corrections. It can be paired with a compatible drive to maintain steady torque response during rapid starts, stops, and direction changes.

A flange diameter of 105 mm sets the mounting footprint, while power and feedback enter through factory-fitted connectors that simplify wiring. The housing carries an ingress rating of IP54, so internal components are protected from limited dust and water spray. Operation is approved from 5 to 40 °C, and the standard-length design maintains thermal balance across that range. Feedback is provided by an encoder, which sends position data to the drive, and the winding is the standard-speed variant for general-purpose servo amplifiers. Cabling exits at an angle on the B-side of the frame, which helps keep space clear at the motor face, and an internal contact at the feedback connector adds protection against induced voltages.

The motor tolerates up to 95% relative humidity in the surrounding air without condensation, which expands its use in humid areas. It is supplied without a holding brake, so any static load must be secured by the drive or by external mechanics. Rotor indexing relies on a single-turn position code, which is suitable for axes that do not exceed one mechanical revolution during homing. Torque is transferred through a shaft machined with a keyway, which helps provide slip-free coupling to pulleys or gearboxes.
