Product Description:
The SE-B2.030.030-10.000 servo motor is built by Bosch Rexroth Indramat as part of the SE Synchronous Servo Motors series. It is a brushless rotary actuator intended for compact machinery that needs accurate positioning and repeatable speed. The unit receives three-phase power from a matched drive and converts it into controlled shaft movement for pick-and-place heads, feed rollers, and small conveyor segments. Its brushless design reduces wear at the motor and supports consistent response during frequent start-stop cycles. This makes the motor suitable for short indexing moves and other compact axes that require stable motion.
At a nominal speed of 3000 rpm, the motor reaches its rated mechanical velocity while remaining within normal thermal limits. It can support a static load with up to 4.1 Nm of torque at the shaft. The winding design produces a torque constant of 1.14 Nm/A, so each ampere of phase current delivers repeatable torque. A back electromotive force of 119 V/1000 rpm gives the voltage constant, allowing the drive to scale output voltage for speed regulation, while the tacho output of 2.7 V/1000 rpm supplies proportional feedback for velocity loops. Electrical dynamics are set by a time constant of 7.3 ms, indicating how quickly stator current rises after a control command.
The motor combines a compact housing with moderate inertia for responsive motion on small machine axes. A rotor inertia of 0.60×10⁻³ kg·m² helps limit overshoot during rapid reversals, and the mass of 7.6 kg keeps handling forces low when mounting to the 100 mm flange. Heat dissipates gradually because the thermal time constant is 18 min, permitting short overloads before steady-state temperature is reached. Winding resistance of 9.5 Ω interacts with current limits; during acceleration, the motor draws 3.6 A at standstill and reaches rated motion in 23 ms. The 254 mm housing carries a Ø14 × 30 mm shaft supplied without a keyway, giving designers flexibility for clamp-style couplings in tight assemblies.
