Product Description:

The SE-B4.130.030-00.033 servo motor is manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It uses permanent-magnet excitation to translate drive current into controlled rotary motion for positioning axes, pick-and-place heads, and other closed-loop automation tasks. The housing matches standard flange patterns and interfaces with IndraDrive or comparable digital inverters. Its synchronous design supports accurate speed regulation and repeatable shaft positioning during frequent start-stop cycles. This arrangement lets the motor serve packaging, transfer, and indexing systems that rely on smooth command tracking under varying load conditions.

Nominal speed is 3000 rpm. The motor tolerates up to 27.6 Nm of torque and draws a transient peak of 84 A from the drive. A torque constant of 0.80 Nm/A shows the relationship between current and torque, while an electrical time constant of 9.7 ms influences current-loop response. Standstill current is 15 A, and static torque is 13 Nm. Speed stabilization is aided by a 3.8 ms mechanical time constant. Power is transmitted through a keyed shaft with a diameter of 24 mm and a length of 50 mm. This shaft format supports positive torque transfer to couplings or pulleys in compact axis assemblies.

Rotor inertia is 3.08 × 10⁻³ kg·m², enabling rapid index moves without excessive controller gain. Overall mass is 16.0 kg and total length is 283 mm, so the unit can be mounted side-by-side in compact machines. A back-EMF slope of 99 V/1000 rpm must be considered when selecting the DC-bus voltage to avoid saturation at high speed. The phase inductance of 9.7 mH helps limit switching ripple in the windings, and a winding resistance of 0.96 Ω contributes to continuous thermal behavior. The combination of moderate inertia and compact dimensions can help shorten settling time in machines that perform frequent reversals.
