Product Description:

The SE-B5.440.020-00.010 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It serves as a rotary actuator in industrial automation, converting controlled current from a drive into precise torque and speed for positioning tasks on gantries, packaging machines, and indexing tables. Its compact construction, closed-loop feedback, and standardized mounting interfaces allow the unit to fit into confined spaces while maintaining accurate motion control.

The motor reaches a nominal speed of 2000 rpm, allowing moderate linear feed rates without imposing high centrifugal forces on connected components. A torque constant of 1.51 Nm/A indicates the proportional relationship between drive current and output torque, simplifying current-loop tuning. During regeneration or rapid deceleration, the back EMF rises at 167 V/1000 rpm, so the inverter must accommodate the resulting voltage. Stator copper loss is directly influenced by a phase-to-phase winding resistance of 0.26 Ω. A winding inductance of 5.0 mH shapes current ripple and affects the switching frequency needed for stable operation.

The rotor has a moment of inertia of 18.6 × 10⁻³ kg·m², enabling rapid acceleration without excessive peak current demand from the drive. Current reaches its steady-state value according to an electrical time constant of 18.6 ms, supporting responsive torque production during frequent motion cycles. The motor has a mechanical time constant of 2.0 ms, allowing its speed to respond quickly to changes in the drive command. A ground shaft journal measuring 32 mm (k5) permits direct connection through compatible couplings or precision clamp collars. The k5 shaft tolerance helps maintain the concentric alignment needed to reduce vibration during repetitive positioning and high-cycle operation.
