Product Description:

The SE-B4.090.030-10.012 is a synchronous servo motor produced 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 drive current into regulated rotary motion for actuators, gantries, and tooling spindles. Its IM B5 end-bell mounting pattern enables direct flange installation against gearboxes or machine frames, allowing quick integration while maintaining axial alignment. This mounting style is suitable for assemblies where the motor must connect directly to the driven mechanism without a separate base.

The motor has a flange diameter of 142 mm, a housing length of 252 mm, and a mass of 13.0 kg. These dimensions support compact placement in machinery while providing enough thermal mass for continuous duty. An ingress rating of IP67 seals the stator against dust and temporary immersion, so the housing can be used in areas exposed to spray and contamination. The motor can deliver 17.3 Nm of torque, while speed regulation extends to 3000 rpm for applications that require quick and repeatable motion. A static torque of 9.0 Nm helps the axis resist load at standstill, and power is supplied through 2.5 mm² leads sized for the intended current load.

Dynamic response is supported by a rotor inertia of 2.18 × 10⁻³ kg·m², which helps the motor accelerate quickly without excessive demand on the drive. With a standstill phase current of 10 A, the motor can hold commanded position while limiting copper losses during low-speed operation. Electromagnetic conversion is indicated by a torque constant of 0.87 Nm/A, allowing output torque to track current feedback in a predictable way. The motor uses a 24 mm plain shaft that projects 50 mm beyond the bearing seat, and the lack of a keyway makes it suitable for clamp couplings and other friction-locking connections.
