Product Description:

The SE-B4.130.030-00.000 is a synchronous servo motor engineered by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. As a rotary actuator, it provides closed-loop speed and torque control that drive controllers rely on for positioning tables, pick-and-place heads, and other precision axes in automated production lines. A permanent-magnet rotor and integrated feedback provisions allow this motor to translate electrical commands into repeatable mechanical motion required by industrial automation tasks.

The motor sustains a nominal speed of 3000 rpm, a reference point that defines the base electrical frequency for the inverter. With a torque constant of 0.80 Nm/A, every ampere of phase current produces a predictable amount of rotary force, while the drive can draw up to 84 A of peak current for rapid acceleration. Its winding inductance is 9.7 mH and resistance is 0.96 Ω; together they establish an electrical time constant of 9.7 ms, indicating how quickly current builds after a voltage step. The rotor can deliver up to 27.6 Nm of maximum torque for short bursts, enabling it to overcome load spikes without stalling. Voltage ripple remains limited to 1.5 %, which reduces torque pulsation and helps achieve smooth velocity profiles.

At standstill the unit generates a static torque of 13 Nm, eliminating the need for a brake in many horizontal applications. Responsiveness is influenced by a rotor inertia of 3.08 × 10⁻³ kgm², balancing quick starts with mechanical stability. An analog tachogenerator provides 2.7 V per 1000 rpm (±5 %) for legacy speed loops. The back-EMF is defined by a voltage constant of 99 V/1000 rpm, which guides DC-bus sizing. Thermal behavior is characterized by a 37-minute time constant, and the overall mass of 16.0 kg contributes to heat capacity. A Ø24 × 50 mm shaft with a DIN 6885 keyway simplifies coupling to standard pulleys or gearboxes.
