Product Description:

The SE-B5.320.020-00.000 is a synchronous servo motor built by Bosch Rexroth Indramat for the SE Synchronous Servo Motors series. Designed for closed-loop motion axes in industrial automation, it converts drive current into controlled rotation for positioning, conveying, or tooling tasks. A frame length of 345 mm and a shaft prepared for an A10x8x50 DIN 6885 feather key simplify mechanical integration with gearboxes or pulleys while maintaining torsional stiffness.

At the output flange, the motor supplies 39 Nm of static torque, giving machinery holding capability before motion begins. Under rated excitation, it reaches a nominal speed of 3000 rpm, pairing medium inertia with rapid cycle times. Torque production scales with current at 1.60 Nm/A, so the drive can predict load behavior precisely. Back EMF rises to 176 V/1000 rpm, a value needed for inverter sizing. The three-phase winding presents 8.7 mH of inductance, which damps current ripple during switching events. Electrical and mechanical time constants of 2.4 ms and 18.0 ms, respectively, show how quickly current and speed respond in servo loops. A 6.0 mm² terminal area simplifies field wiring, and the Ø32 k5 shaft diameter keeps deflection minimal under load.

The dynamic profile is further characterized by a rotor inertia of 13.6 ×10⁻³ kg·m², balancing acceleration capability against load stability. An enclosure rated IP65 seals the stator against dust and water, widening mounting options on processing lines. The total mass is 31 kg, providing thermal capacity that works with a winding resistance of 0.47 Ω to moderate temperature rise during continuous duty. Mechanical coupling remains secure through the DIN feather key, and the overall length leaves room for feedback devices without exceeding standard motor bays.
