Product Description:

The SE-B2.040.060-01.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for mounting on 100 mm machine frames, it converts controlled current from a compatible drive into precise rotary motion. In industrial automation, this motor supplies closed-loop actuation for compact robot joints, feeder lines, and other equipment that demands stable velocity regulation and rapid dynamic response.

Its mechanical interface uses a square flange measuring 100 mm, while the output shaft is 14 mm in diameter and 30 mm long to accept standard couplings. Under rated conditions, the rotor turns at 6000 rpm, and the motor can provide 4.0 Nm of static torque when regulated by the control loop. The torque constant is 0.40 Nm/A, indicating the relationship between phase current and shaft torque. Current changes quickly because the electrical time constant is only 6.6 ms, enabling fast torque modulation during positioning moves. The winding has an inductance of 9.4 mH and a resistance of 1.40 Ω, supporting responsive current control while limiting copper losses during operation.

When acceleration is commanded, the motor can reach its set speed in 64 ms because the rotor inertia is just 0.75 × 10⁻³ kg·m², while the mechanical time constant is 6.0 ms. A momentary peak current of 60 A is permissible, allowing the motor to produce up to 8.0 Nm for overcoming load peaks before the controller settles at the standstill current of 10 A. The winding system has a thermal time constant of 25 min, allowing temperature to rise gradually during cyclic operation. With a voltage constant of 45 V per 1000 rpm, the generated back electromotive force remains suitable for compatible servo inverters. The stated acceleration time also supports predictable speed changes during coordinated multi-axis starts.
