Product Description:

The SE-B2.020.060-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop industrial automation, the unit converts drive current into precisely controlled mechanical rotation so linear actuators, indexing tables, or compact robotic joints can follow programmed motion profiles with minimal position error. Its compact format suits motion systems that need responsive positioning in a limited installation space.

At a nominal speed of 6000 rpm, the motor supports fast cyclical operations on packaging or assembly lines. The torque constant is 0.40 Nm/A, so each ampere delivered by the drive produces 0.40 newton-meters at the shaft. During acceleration bursts, the stator windings may draw up to 30 A, while steady holding conditions require a standstill current of 5.0 A. The induced back EMF follows a motor voltage constant of 46 V per 1000 rpm, which aligns with the tachogenerator signal of 1.8 V per 1000 rpm used for analog speed monitoring. Resistive copper loss is limited by a winding resistance of 4.43 Ω, and current rise time is governed by an electrical time constant of 10.2 ms. Both values affect the current-loop bandwidth used by the servo drive.

Dynamic behavior on the mechanical side is established by a rotor inertia of 0.44×10⁻³ kg·m², yielding a mechanical time constant of 4.6 ms between commanded and measured speed. The motor can exert 2.0 Nm of static torque at zero speed, giving sufficient holding force for light vertical loads when power remains applied. Overall package length is 230 mm and the assembly weighs 6.5 kg, allowing direct mounting on small machine frames. A winding inductance of 20.8 mH filters switching harmonics from pulse-width-modulated drives, which helps reduce torque ripple during slow moves. The precision-ground steel shaft has a 14 mm k5 fit and extends 30 mm, permitting rigid coupling to planetary gearboxes or timing pulleys without additional sleeves.
