Product Description:

The SE-B2.040.060-04.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied as part of the SE Synchronous Servo Motors series. With a 100 mm square flange, an 8.8 kg mass, and an overall length of 277 mm, the unit fits compactly into servo axes that demand high rotational accuracy. Its 14 mm shaft couples directly to gearboxes or pulley drives, allowing the motor to deliver controlled torque for pick-and-place arms, feeders, and similar automation tasks where precise motion profiles are required.

The drive delivers continuous motion at a nominal speed of 6000 rpm, and each ampere of phase current produces 0.42 Nm/A of torque, so current commands from the controller translate predictably into mechanical output. During rapid acceleration or load shocks, the winding can accept a peak draw of 60 A, while the lightweight rotor, whose inertia is only 0.75 × 10⁻³ kg·m², lets the axis change speed quickly without excessive drive effort. A winding inductance of 9.4 mH filters current ripple, supporting stable closed-loop control even when the inverter uses high-frequency switching. Voltage ripple across the terminals is held to 1.5% or less, limiting electrical oscillations that might otherwise disturb sensitive positioning applications.

Dynamic responsiveness is quantified by a mechanical time constant of 6.0 ms; this short delay between torque command and speed rise promotes tight follower performance in interpolated motion. Thermally, the motor’s copper and frame reach equilibrium after a 25 min thermal time constant, allowing intermittent overloads without surpassing insulation limits. Back-EMF develops at 45 V/1000 rpm, giving the drive predictable voltage requirements throughout the speed range, while a standstill phase current of 10 A is sufficient to hold rated torque when the shaft is stationary.
