Product Description:

The SE-B3.055.060-00.000 is a synchronous servo motor built by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. Designed for industrial automation, it produces precisely regulated rotary motion for indexing tables, pick-and-place axes, and high-speed spindles. Electrical energy from the servo amplifier is converted into torque on a keyed shaft, while the internal feedback system allows the controller to maintain commanded motion under dynamic load changes.

The motor uses an IM B5 mounting configuration, with its 116 mm flange located against a rigid machine plate to center the stator housing. When energized, the unit can deliver up to 16.2 Nm of torque for short duty cycles. The rated shaft speed is 6000 rpm, supporting applications that require rapid and precisely controlled rotation. To meet acceleration demands, the windings can momentarily absorb a peak current of 76 A, while the standstill current is limited to 12.6 A. The enclosure has an ingress protection rating of IP67, sealing the motor against dust and temporary submersion for operation in washdown or coolant-rich areas. A keyed shaft measuring 19 mm in diameter and 40 mm in length prevents coupling slip under intermittent reversing loads.

The moving assembly has a moment of inertia of 1.21 × 10⁻³ kg·m², allowing rapid speed changes without requiring excessive drive gain. During holding states, the motor supplies 6.5 Nm of static torque, helping vertical axes maintain position with minimal closed-loop error. The torque constant is 0.52 Nm/A, while the back EMF is 61 V/1000 rpm and the tachogenerator provides an output of 1.8 V/1000 rpm for analog speed feedback. Phase resistance measures 1.03 Ω, which affects copper losses under continuous load. The motor weighs 10.2 kg and measures 256 mm in overall length. Its windings are contained within a sealed casting, and the frame’s thermal mass helps slow temperature increases during prolonged standstill operation.
