Product Description:

The SE-B2.040.060-00.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. This brushless unit interfaces with digital drives to deliver regulated torque and velocity, forming the primary mover for indexing tables, electronic camming axes, and multi-axis gantries. By translating controlled three-phase current into immediate rotor motion, the motor supports automated assembly cells and packaging equipment that require fast, repeatable positioning and precise process timing.

At its nominal operating point, the rotor reaches 6000 rpm while providing a static torque of 4.0 Nm. The electromagnetic design produces approximately one newton-meter of torque for every 2.4 A increase in phase current, based on a torque constant of 0.42 Nm/A. Short bursts of up to 60 A allow the shaft to overcome inertia during rapid indexing, whereas continuous standstill operation draws 10.0 A. An electrical time constant of 6.6 ms characterizes current buildup and, in combination with the 45 V/1000 rpm voltage constant, influences the drive’s current regulator bandwidth. Mechanical power is transferred through a 14 mm shaft that extends 30 mm and accepts an A5 × 5 × 25 mm key. The aluminum housing measures 277 mm in length, allowing installation in machine frames with limited space.

Dynamic behavior depends on a mechanical time constant of 6.0 ms and rotor inertia of 0.75 × 10⁻³ kg·m², allowing the drive to accelerate the load without excessive servo gain. The motor has a mass of 8.8 kg, which supports moving-axis installation while helping damp vibration. Electromagnetic parameters include a winding inductance of 9.4 mH and a phase resistance of 1.40 Ω, which affect thermal dissipation and the current-loop response during regenerative braking.
