Product Description:

Bosch Rexroth Indramat produces the SF-B4.0230.060-00.050 as a servo motor in the SF Servo Motors series. The unit is a brushless permanent-magnet motor intended for closed-loop positioning in transfer lines, handling modules, and general automation. Its compact form supports installation where controlled rotary motion must be delivered in limited space without adding separate mechanical transmission stages. When combined with a compatible Indramat drive controller, it delivers programmable speed and torque profiles and can be flange-mounted, coupled to timing belts, or connected directly to ball-screw inputs.

The motor is designed for a DC bus of 670 V, enabling compatibility with high-voltage inverters that reduce phase current for the same power level. Feedback is returned through a 17-pin encoder socket that carries incremental position signals, temperature leads, and shielding in one molded connector. During start-up or shaft blockage, the drive may draw 25 A of locked-rotor current, while mechanical output can reach 22 Nm of locked-rotor torque for breakaway loads. Power conductors are routed through a 1.5 motor connector (8-pin) that separates phase wiring from feedback leads. Acoustic emission is limited to 58 dB(A), so the unit can operate on open machine frames without excessive ambient noise. The housing follows the IM B5 mounting layout, providing a flange face for rigid coupling to gearboxes or machine plates.

Dynamic behavior is characterized by a nominal shaft speed of 6000 rpm, allowing rapid indexing when paired with a correctly sized gearbox. The magnetic circuit develops 0.88 Nm/A of torque per phase ampere, giving the controller a linear relationship between commanded current and mechanical output. Mechanical endurance extends to 6 g of shock resistance, helping the motor withstand transport impacts or abrupt machine stops without encoder misalignment. This combination favors axes that need quick acceleration and repeatable motion under changing loads. The motor is suitable for pick-and-place axes, textile winders, and light packaging actuators that require high speed, moderate stall torque, and low acoustic output.
