Product Description:

The SE-B4.130.050-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. This motor converts controlled electrical input into precise shaft motion, enabling tight position and velocity regulation in automated assembly stations, pick-and-place heads, and high-speed packaging lines. Its compact construction supports integration into machinery where dynamic response and repeatable accuracy are required.

The motor mounts on a 142 mm square flange, and its housing reaches a maximum length of 283 mm, allowing installation in tight servo axes. A shaft with a 24 mm diameter and 50 mm length transmits motion directly to couplings or gear stages without additional adapters. Under rated conditions, the rotor spins at 5000 rpm, and the drive reaches that speed from rest in 61 ms, which supports short machine cycle times. Continuous holding capability is provided by 11 Nm of static torque, while electrical demand remains moderate at a standstill current of 18 A. During acceleration, the inverter may supply up to 108 A, and the stator has a winding inductance of 6.3 mH and a resistance of 0.61 Ω. With a back-EMF constant of 71 V per 1000 rpm, the motor pairs with common 560 V DC bus drives.

For transient loads, the servo delivers 34.0 Nm of peak torque without loss of synchronization. Dynamic behavior is aided by a rotor inertia of 3.08 × 10⁻³ kg·m², which helps keep overshoot low when following fast command changes. The assembled unit weighs 16.0 kg and occupies minimal cabinet space because of its compact stator stack. Thermal modeling indicates a 28 min time constant, so temperature rises gradually during high-duty cycles and permits extended production runs. A torque constant of 0.61 Nm/A gives the relationship between phase current and developed torque, which helps simplify current-loop tuning in the drive controller.
