Product Description:
Bosch Rexroth Indramat manufactures the SE-B5.440.030-00.015 as part of its SE Synchronous Servo Motors series. This brushless AC unit is a closed-loop drive element intended for positioning and speed-regulated axes in production cells, handling modules, and packaging lines. The motor’s IM B5 construction integrates a flange face for direct mounting to gearboxes or machine plates, allowing efficient integration of drive power into automated equipment where consistent torque and repeatable motion profiles are required.
The motor reaches a nominal speed of 3000 rpm while drawing a standstill current of 47 A, providing the continuous operating range needed for applications with high cycle rates. A flange diameter of 180 mm sets the mating surface size, and a shaft diameter of 32 mm provides the torsional interface for couplings or pulleys. Mechanical locking is handled by a DIN 6885 A10×8×50 feather key that engages the driven element. The centering hole follows DIN 332-DR M12, aligning the motor concentrically during installation. Power conductors up to 16.0 mm² can be terminated at the stator connectors, matching the thermal capacity of the copper paths. Under rated load, the acoustic emission does not exceed 58 dB(A), permitting placement near operator workstations without additional enclosure treatments.
The housing has an IP65 protection rating, sealing it against dust ingress and low-pressure water jets. The ground shaft projects 58 mm beyond the flange, providing sufficient engagement for hub clamping devices. In dynamic assemblies, the motor tolerates shocks of up to 6 g without impairing bearing alignment. Rotor speed can be monitored by a tachogenerator that supplies 2.7 V/1000 rpm; this analog feedback supports legacy drive amplifiers that rely on proportional voltage sensing. An internal thermistor connects to the drive’s thermal model and provides temperature data that can be used to protect the windings during sustained loading. The ±15 V DC sensor rail powers auxiliary feedback electronics without requiring a separate power supply.
