Product Description:

The SE-B3.055.030-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the SE Synchronous Servo Motors series. The unit is built for closed-loop motion tasks in industrial automation, where it converts commanded current into precisely regulated shaft torque and speed. It is suitable for positioning tables, pick-and-place axes, and similar equipment that requires accurate, repeatable movement.

This motor reaches a nominal speed of 3000 rpm, giving controllers a predictable velocity reference under rated load. A static torque of 6.8 Nm is available at zero speed for holding duties, while the standstill current requirement is 6.7 A. During acceleration or impact loads, the drive can deliver a peak current of 40 A without loss of synchronization. Current rise is limited by an electrical time constant of 3.8 ms, and the rotor responds with a mechanical time constant of 8.4 ms; these values influence the dynamic response of the servo loop. The rotor accelerates from rest to rated speed in 53 ms, supporting machines with short operating cycles. The stator has a winding inductance of 30 mH and a winding resistance of 3.53 Ω, which affect drive sizing, PWM frequency, and copper loss calculations.

The motor can produce a maximum torque of 16.2 Nm during brief overloads, and heat accumulation is moderated by a thermal time constant of 29 min. This thermal response permits intermittent high-duty operation before the motor reaches its temperature limit. Torque rises in proportion to current at 1.02 Nm/A, while the generated back EMF has a voltage constant of 113 V/1000 rpm. These electrical values assist with control gain settings and regenerative braking calculations. The housing is 256 mm long, and the shaft measures 19 × 40 mm for direct coupling. The motor has an overall mass of 10.2 kg, which is relevant when calculating load inertia and planning the mounting arrangement.
