Product Description:

The SE-B2.040.030-00.015 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. The unit converts drive controller current into mechanical rotation for positioning and velocity tasks in automated machinery, packaging stations, and transfer axes. Its rotor couples to loads through a keyed shaft, allowing direct transmission of motion without intermediate gearing.

The motor develops a continuous holding capacity of 5.0 Nm at standstill, providing enough torque to keep static loads from drifting when the axis is energized. During accelerations, it can accept up to 26 A of phase current at 20 °C, which indicates the peak inverter output required for fast cycle moves. At its rated operating point, the rotor turns at 3000 rpm, a speed that balances magnetic flux utilization with bearing life in general-purpose servo applications. Copper loss is governed by a phase resistance of 6.4 Ω measured at 20 °C, and this value can be used to estimate thermal rise during continuous duty. With a torque constant of 1.14 Nm/A, each ampere of stator current produces a proportional electromagnetic moment, which helps support predictable load control.

The square 4-bolt pattern on the flange measures 100 mm, providing a standard interface for gearboxes or mounting plates, while an IP67 rating on the A-flange keeps dust and water from entering during washdown or cutting-fluid exposure. Dynamic response is aided by a rotor inertia of 0.75 × 10⁻³ kg·m², so speed changes can occur quickly without excessive controller gain. For short bursts, the winding can deliver up to 13.2 Nm when paired with SM10/20 cooling, extending acceleration capability. Additional attributes include a 54 mH phase inductance, a 112 V/1000 rpm back-EMF constant, a 277 mm overall length, and a 14 × 30 mm keyed shaft with a radial lip seal.
