Product Description:

The SE-B3.055.060-00.101 synchronous servo motor is produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It functions as a rotary actuator that supplies controlled speed and torque to tooling, indexing tables, and material-handling systems where precise motion cycles are required. By converting drive current from a servo amplifier into mechanical rotation, the motor serves as the dynamic element of a closed-loop axis in industrial automation cells. Its compact build supports high shaft speeds while maintaining the repeatable positioning accuracy required by pick-and-place machines and small machining centers.

At a nominal speed of 6000 rpm, the motor responds to rapid command updates, while its rotor inertia of 1.21 × 10⁻³ kg·m² helps maintain responsive motion. The standstill torque is 6.5 Nm, and the locked-rotor current is 12.6 A. A torque constant of 0.52 Nm/A relates phase current to developed torque, and a back-EMF constant of 61 V/1000 rpm indicates the voltage generated during motion. These values help the drive remain within its thermal and current limits during operation. An oil-tight drive-end plate seals the bearings, the 116/105 mm flange aligns the housing, and a 19 × 40 mm keyed shaft transmits torque without slipping.

When rapid indexing is required, the motor withstands transient peaks of up to 16.2 Nm when paired with an SM 17/35 amplifier. Thermal energy from these bursts is absorbed by the stator, whose winding inductance of 11 mH filters current ripple and whose winding resistance of 1.03 Ω determines copper losses. Heat dissipates over a thermal time constant of 28 minutes, permitting intermittent overload before the motor reaches its steady-state temperature. The overall length is 256 mm, allowing installation where axial space is limited. The integrated tacho generator produces 1.8 V per 1000 rpm with a tolerance of ±5%, providing real-time speed feedback to the controller.
