Product Description:

The SE-B2.040.030-10.037 is a synchronous servo motor produced by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. It is intended for closed-loop positioning and velocity control in industrial automation where compact electromechanical actuators are preferable to hydraulic or pneumatic drives. The motor converts drive current into rotary motion through permanent-magnet excitation. Its feedback system allows the connected controller to regulate torque and speed accurately during changing load conditions.

The motor develops a continuous static torque of 5.0 Nm, giving machines a predictable holding force at zero speed. Its nominal operating point is reached at 3000 rpm, a speed that matches many gearbox ratios used in pick-and-place axes. The motor generates 1.14 Nm/A per ampere of phase current, so torque demand scales linearly with commanded current. During acceleration, the drive can deliver up to 26 A. The windings respond to current changes within an electrical time constant of 8.1 ms, supporting controlled current regulation during point-to-point moves and contouring tasks.

The short-term overload margin peaks at 13.2 Nm, enabling the axis to overcome frictional or inertial disturbances. Total rotor inertia, including the tachogenerator, is 0.75 × 10^-3 kg·m², limiting overshoot and supporting quick reversals. A back-EMF gradient of 112 V/1000 rpm helps ensure that the inverter can supply adequate voltage at maximum speed. The stator has an inductance of 54 mH, which filters current ripple, while the mechanical time constant of 4.3 ms indicates how quickly the rotor reaches its target speed. At standstill, the motor draws 4.5 A, and its winding resistance of 6.4 Ω contributes to thermal losses under continuous load. The smooth Ø14 × 30 mm shaft without a keyway is suitable for clamp couplings. The assembly has a mass of 8.8 kg, allowing it to be mounted on light machine frames.
