Product Description:

The SE-B5.320.020-10.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SE Synchronous Servo Motors series. Designed for closed-loop positioning and velocity control in automated machinery, the unit converts electrical energy into regulated mechanical torque for axes that demand precise response. Its construction supports direct coupling to gearboxes or mechanical linkages commonly found in packaging lines, transfer systems, and material-handling stations.

The electromagnetic output begins with a static torque capability of 39 Nm, allowing the axis to hold a load at standstill without external brakes. During motion, the magnet-to-winding geometry sets a torque constant of 1.60 Nm/A, giving predictable proportionality between drive current and shaft torque. As speed builds, the motor generates a back electromotive force of 176 V/1000 rpm, so the controller must provide matching voltage overhead. Dynamic current change is influenced by a winding inductance of 8.7 mH, while copper losses are tied to the coil resistance of 0.47 Ohm. These electrical values influence current response, voltage demand, and heating behavior during acceleration, reversal, and steady operation.

Mechanical dimensions include a 180 mm flange, a 345 mm overall length, and a 32 mm by 58 mm shaft, which support rigid mounting and stable torque transfer through couplings or hubs. Continuous operation is specified at a nominal 2000 rpm, yet the rotor can deliver up to 90 Nm for short overloads without demagnetization. The aluminum housing is sealed to IP65, so airborne dust and coolant spray are kept out, and the motor withstands shocks as high as 6 g. At 31 kg, the frame adds thermal mass that helps moderate temperature rise during repeated load changes. An integrated tachogenerator yields 2.7 V/1000 rpm with only 1.5 % ripple, providing analog speed feedback for legacy drive systems that rely on a stable velocity signal.
