Product Description:

The SE-B3.055.060-04.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. As a compact rotary actuator, it converts drive current into controlled mechanical rotation for positioning tasks in automated machinery, packaging stations, and pick-and-place modules. The motor’s integrated electromagnetic brake supports controlled stopping and load retention when the axis is stationary. Its sealed housing also supports operation in washdown areas where protection from water and solid contaminants is required.

This model reaches a nominal speed of 6000 rpm, enabling short cycle times without external gear reduction. The motor provides 6.8 Nm of static torque, allowing the shaft to resist load forces while stationary. The brake coil accepts a control voltage of 24 V DC, allowing it to operate with a standard machine control supply. An enclosure rating of IP67 protects the windings, resolver, and bearings against dust and temporary immersion in water. The motor has a total mass of 10.9 kg with the brake installed, which is relevant when calculating moving-axis inertia and structural loads.

The overall length, including the brake, is 295 mm, allowing the motor to fit within common gantry beam clearances and other restricted installation spaces. During transport or installation, it withstands shocks of up to 6 g, helping prevent internal magnet or encoder movement. A shaft diameter of 19 mm accommodates standard zero-backlash couplings, and the keyless shaft design simplifies alignment when the motor is connected directly to a precision ball screw. The power connection accommodates conductors with a cross-sectional area of 2.5 mm², matching common servo-grade cable sets and drive terminal blocks. The motor uses an IM B5 flange pattern with a centering diameter of 110 mm and an M6 centering hole. Its flange is 116 mm wide, while the shaft extension measures 40 mm for connection to compatible metric motor adapters and gearbox inputs.
