Product Description:
The SE-B2.020.030-14.000 synchronous servo motor is manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. It functions as a compact rotary drive that translates commanded current into precise angular displacement for pick-and-place heads, carton erectors, and small positioning stages in automated lines. Integrated speed feedback from an internal tachogenerator allows the controller to close the velocity loop, so the motor keeps its programmed profile when load or supply conditions change. Its frame size and connector geometry match other SE motors used in modular machine frames.
At the nominal operating point, the rotor reaches 3000 rpm. The motor produces 2.9 Nm of static torque at standstill with 2.7 A of phase current. The electromagnetic design yields a torque constant of 1.10 Nm/A, so each ampere delivered by the drive produces predictable output torque. Dynamic response starts with an electrical time constant of 5.0 ms, meaning phase current rises quickly after a command, while the mechanical portion is completed in 4.8 ms as the rotor accelerates. Stator inductance is 76 mH, and it works with the 14.7 Ω winding resistance to shape current loops and reduce ripple. A back electromotive force of 16 V/1000 rpm is used in drive voltage calculations, and the plug-in power connector accepts 1.5 mm² conductors. Because the shaft is supplied without a keyway, coupling parts must rely on clamp hubs or shrink discs.
In transient conditions, the drive may command a peak phase current of 24 A, enabling the motor to generate 6.9 Nm of torque for brief acceleration or braking periods. This reserve is assisted by a low rotor inertia of 0.44×10⁻³ kg·m², so the system reaches target speed quickly with minimal overshoot. A holding brake fed with 24 V DC can secure the shaft during power-off states. The tachogenerator delivers 2.7 V/1000 rpm, giving the controller an analog speed reference that remains linear across the working range.
