Product Description:
The SE-B3.055.030-00.037 is an AC synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. Serving as the electromechanical actuator in a drive system, it converts regulated three-phase current into precise shaft rotation that can be coordinated by CNC or PLC controllers. This model is intended for medium-duty axes in packaging machines, pick-and-place modules, and material-handling equipment where stable torque delivery, quick reversals, and repeatable positioning accuracy are required.
At rated conditions, the motor develops a static torque of 6.8 Nm, allowing it to hold loads at zero speed without thermal overload. The associated standstill current of 6.7 A is the continuous phase current required to produce that torque. A torque constant of 1.02 Nm/A provides nearly linear current-to-torque conversion, simplifying drive tuning. Because the back electromotive force rises by 113 V/1000 rpm, the inverter must supply proportionally higher voltage as the shaft accelerates toward the nominal speed of 3000 rpm. The phase inductance of 30 mH damps current ripple, while the phase resistance of 3.53 Ω contributes to copper losses and affects the thermal sizing of the controller. These values provide the drive controller with the electrical data needed to regulate current during acceleration, steady motion, and operation at zero speed.
Mechanical integration is aided by a rotor inertia of 1.21 × 10-3 kg·m², providing a balance between quick acceleration and smooth load regulation. The square flange measures 116 × 116 mm and follows the IM B5 face-mount format, while a pilot diameter of 110 mm centers the housing on the mounting surface. Output power passes through a 19 × 40 mm shaft fitted with an A6 × 6 × 32 feather key for positive torque transfer to couplings or gearboxes. The overall length is 256 mm, allowing installation in compact machine layouts, and the unit weighs 10.2 kg. During transportation or service, the motor can withstand shocks of up to 6 g without compromising its alignment or magnetic integrity. The keyed shaft supports secure coupling under reversing loads, while the centered flange helps maintain proper alignment with connected mechanical components.
