Product Description:
The SE-B2.040.060-00.003 synchronous servo motor is manufactured by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. The unit provides closed-loop rotational actuation in industrial automation, coupling with drives to move gantries, rotary tables, and feeder mechanisms where precise velocity and torque regulation are required. Its compact frame, standardized flange, and low rotor inertia make it suitable for rapid indexing duties in packaging and electronics assembly.
The motor reaches a nominal speed of 6000 rpm, allowing high cycle rates. A torque constant of 0.42 Nm/A links drive current to developed torque, so 5 A produces about 2.1 Nm. At standstill, the phase current may reach 10 A, which is the continuous current that can be applied without excessive heating. Dynamic positioning is aided by the rotor inertia of 0.75 ×10⁻³ kg·m², limiting kinetic energy and shortening deceleration times. Current rise is shaped by a stator inductance of 9.4 mH, and the winding resistance of 1.40 Ω contributes to the electrical time constant seen by the servo amplifier. The required power lead cross section is 1.5 mm², matching common industrial cable sizes.
The back electromotive force constant is 45 V/1000 rpm, so the drive must supply about 270 V when the shaft turns at rated speed. Electrical dynamics are further characterized by a time constant of 6.6 ms, while the mechanical time constant is 6.0 ms. Reference speed feedback can also be taken from the tacho output of 1.8 V/1000 rpm. The motor tolerates vibration and impact up to 6 g and produces a sound pressure of 58 dB(A). A flange pilot diameter of 95 mm centers the housing, and the 14 mm diameter shaft extends 30 mm beyond the face for coupling. Shock-proof bearings help the motor remain stable during repeated duty cycles.
