Product Description:

The SE-B3.055.060-10.000 belongs to the SE Synchronous Servo Motors series manufactured by Bosch Rexroth Indramat. It serves as a compact rotary actuator for CNC stations, pick-and-place modules, and other axes that demand precise velocity and position control inside automated machinery. Its compact format supports responsive axis motion in installations where available mounting space is limited.

During continuous operation, the motor reaches a nominal shaft speed of 6000 rpm, allowing high cycle rates without gear reduction. A static torque of 6.5 Nm is available at standstill for holding or low-speed indexing, and every ampere delivered to the windings produces torque according to the 0.52 Nm/A torque constant. Transient load surges can be supplied by a peak phase current of 76 A. Current rise is influenced by a winding inductance of 11 mH and a resistance of 1.03 Ω, and the electrical time constant of 10.2 ms indicates how quickly current builds in the winding. The standstill current requirement is 12.6 A, and rotor acceleration follows a mechanical time constant of 4.1 ms, supporting rapid speed changes between process steps.

For short bursts, the shaft can deliver a maximum torque of 16.2 Nm. The rotor carries an inertia of 1.21 × 10⁻³ kg·m², which balances quick reversals with stable regulation. Thermal behavior is moderated by a 28 min thermal time constant, so brief overloads do not immediately cause derating. Back EMF develops proportionally to speed at 61 V/1000 rpm, which helps determine the required voltage headroom for the matching drive. The housing measures 256 mm in overall length, weighs 10.2 kg, and uses a Ø19 × 40 mm shaft for direct coupling to belts, pulleys, or planetary gearheads.
