Product Description:

The SE-B3.095.030-04.015 is a rotary actuator in the SE Synchronous Servo Motors series manufactured by Bosch Rexroth Indramat. Within an automation cell, it converts drive current into regulated mechanical power so positioning tables, pick-and-place heads, or packaging spindles can move with repeatable accuracy. A closed-loop drive controller monitors rotor position and current, then commands the motor to follow target profiles for indexing or contour-tracking tasks that require steady torque across a broad speed range.

At standstill, the motor can supply 11.6 Nm of static torque while drawing 10.5 A. This operating point reflects the winding resistance, copper fill, and magnetic circuit. The rated mechanical velocity is 3000 rpm, which suits direct coupling as well as geared motion systems. Transient load spikes are handled with a peak phase current of 63 A, which the power section must deliver without saturating the stator. Each ampere of phase current produces approximately 1.10 Nm/A, so torque output rises proportionally through the continuous operating range. A mutual inductance of 18 mH helps smooth current ripple, which supports stable control behavior and reduces audible noise from PWM switching.

An electromechanical brake supplies 8.0 Nm to hold vertical axes during power-off and operates from a 24 V ±10% supply with a nominal coil current of 0.8 A. Back electromotive force rises at 118 V/1000 rpm, so the drive must accommodate that voltage during deceleration and regeneration. Dynamic response is influenced by a rotor inertia of 2.07 × 10⁻³ kg·m², which balances acceleration capability with load matching. For brief overload duty, the unit delivers up to 18.4 Nm. The motor uses a Ø19 × 40 mm shaft with an A6 × 6 × 32 key, and a 116 mm square flange provides a standardized mounting pattern for compatible machine frames.
