Product Description:
The E3.SM.001.4400 is produced by KEB for the SM Synchronous Servo Motors series. It is a synchronous servo motor intended to provide precise rotary motion in automated machinery that requires quick acceleration and repeatable positioning. By combining permanent-magnet excitation with feedback sensing, the motor delivers closed-loop performance for packaging stations, material-handling axes, and general-purpose assembly equipment. The motor responds to commands from a compatible servo drive, which regulates its torque, speed, and position throughout each operating cycle.
The frame uses a terminal box connection, allowing power and signal leads to be attached without plug connectors. The windings rely on self-cooling, so no external blower is required. A continuous stall torque of 29 Nm supports static load holding, while the motor reaches a rated speed of 4000 rpm for fast indexing cycles. Its electromagnetic circuit is rated for 330 V when paired with a 400 V-class inverter and a 560 V DC link, allowing the drive to maintain torque across the working speed range. The B5 IFT5-compatible flange aligns with standard IEC gearheads. The E3 frame size provides mounting geometry suitable for motors in the same power range.
The enclosure is sealed to IP54, protecting internal components against limited dust ingress and water spray. Rotary position is reported by a 2-pole resolver SSBH-15-E-5, which provides analog sine-cosine feedback to the drive controller. For vertical axes or applications that require static load retention, the motor is supplied with a brake. The integrated brake holds the shaft without requiring separate external braking hardware. The motor has a total mass of 17.4 kg, which should be considered when it is installed on a gantry or robot arm. Output torque is transmitted through a shaft with a feather key, enabling positive engagement with pulleys, gearboxes, or rigid couplings. The terminal box, keyed shaft, resolver, brake, and flange provide separate interfaces for electrical connection, feedback, load retention, and mechanical installation.
