Product Description:

Bosch Rexroth Indramat manufactures the SE-B3.095.030-14.150 servo motor for the SE Synchronous Servo Motors series. The unit is a brushless, permanent-magnet device intended to drive tightly regulated axes in pick-and-place modules, conveyors, and tool heads within industrial automation. Integrated feedback signals allow the paired drive controller to close the velocity and position loops so that commanded movements are reproduced accurately under varying mechanical loads. Its compact frame simplifies installation in multi-axis assemblies.

The motor reaches a rated shaft velocity of 3000 rpm, allowing stable synchronization with 50 Hz and 60 Hz drive outputs. At standstill, it supplies 11.6 Nm of static torque, and its short-duty overload capacity reaches 18.4 Nm. A torque constant of 1.10 Nm/A links output torque to phase current so the drive can calculate current setpoints precisely. The electrical time constant is 2.8 ms, which supports rapid changes in commanded current. During acceleration, the stator can accept 63 A of peak current, while continuous operation typically draws the 10.5 A standstill value. Copper resistance is 1.68 Ω at 20 °C, and self-inductance is 18 mH, which influence current ripple and drive PWM behavior. A 19 mm shaft with a 40 mm extension offers direct coupling to belt pulleys or low-backlash gearheads.

A mechanical time constant of 10.8 ms relates rotor inertia to available torque and shows how quickly the motor can reach a new speed setpoint after a command change. Back EMF is quantified by the 118 V/1000 rpm voltage constant, and drive hardware uses that value to predict regenerated energy during deceleration. Heat soak behavior is expressed by the 35 min thermal time constant, which gives a clear window for intermittent overloads before winding temperature rises to its limit. The holding brake circuit engages through a 24 VDC control line, allowing vertical axes to maintain position when the drive is disabled.
