Product Description:

The SE-B3.055.030-14.000 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. Intended for precision drive tasks in automated assembly lines, pick-and-place stations, and packaging machinery, the motor converts regulated current from a digital drive into controlled rotational motion that can be closely coordinated with sensors and PLC sequences. Its sealed construction tolerates coolant mist and airborne oil, making it suitable for industrial environments where process fluids may be present near the motion system.

Rated operation at 3000 rpm establishes the motor’s nominal velocity, while a torque constant of 1.02 Nm/A supports straightforward current-based control by the drive electronics. The brake release coil operates at 24 V DC; when power is removed, the spring-applied brake clamps the shaft with 8.0 Nm of holding torque to prevent load drift on vertical or suspended axes. The package remains compact because the housing, including the brake, measures 295 mm in length and weighs 10.9 kg. At standstill, the windings can deliver 6.8 Nm of static torque, providing enough reserve to overcome seating friction without exceeding the applicable thermal limits.

The motor uses the IM B5 construction type and mounts to a flange with a 110 mm pilot that keeps the 40 mm shaft extension aligned. The output shaft has a diameter of 19 mm and accepts keyed couplings for positive torque transfer. The enclosure has an IP67 protection rating, providing complete protection against dust ingress and resistance to temporary water immersion. Internal components withstand production shocks of up to 6 g, and the windings carry a standstill current of 6.7 A without exceeding insulation limits. Power enters through a connection area sized for 2.5 mm² conductors, keeping the conductor cross section appropriate for the servo motor’s continuous load profile.
