Product Description:

The SF-B5.0250.030-10.011 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. With a B5 flange and the IM B5 construction code, it uses an output-side main bearing that supports radial and axial loads from the driven shaft. In automated systems, this motor converts controlled electrical energy into precise rotary motion, making it suitable for positioning tables, packaging axes, and similar closed-loop tasks. Its layout suits applications that need accurate motion while keeping the motor directly aligned to a machine flange.

The internal power electronics are designed for a DC link of 670 V, so the paired drive converter must deliver that voltage level for full performance. When the rotor is locked, the winding draws up to 16 A, so protective devices must be selected for that short-term current demand. At stall, the shaft can resist a load of 23 Nm, allowing the axis to hold position against static process forces during startup. Under rated conditions, the motor reaches 3000 rpm, a speed that matches common servo gear ratios in medium-throughput machinery. The electromagnetic design yields a torque constant of 1.44 Nm/A, so each ampere of phase current contributes proportionally to output torque and supports current-based control.

Mechanical integration uses a flange diameter of 190 mm that complies with the mounting pattern in IEC 72-2 / DIN 42 948. Power is supplied through a size-1 circular connector, and the stator terminals accept conductors up to 4 x 2.5 mm², which helps keep wiring secure inside standard control enclosures. The housing tolerates impacts up to 6 g, so it remains stable on machines exposed to sudden indexing stops or pallet transfers. This combination of mounting dimensions, terminal capacity, and impact resistance supports installation on equipment with repeated start-stop motion and limited cabinet wiring space.
