SF-A4.0091.060-10.015

The Bosch Rexroth Indramat SF-A4.0091.060-10.015 brushless servomotor, part of the SF Servo Motors series, delivers industry-leading dynamics and precision for advanced motion control systems. Designed by Bosch Rexroth Indramat, this unit features a locked rotor torque (m0) of 9.1 Nm and a torque constant (kt) of 0.65 Nm/A, ensuring efficient torque output matched to current input. The rated speed (nn) of 6000 min⁻¹ enables high-speed positioning, while the optional Encoder Type: Single-turn (STG), Multi-turn (MTG), or Resolver provides versatile feedback solutions. With a mass without holding brake (m) of 13 kg and a compact flange size (sw) of 142 mm, the SF-A4.0091.060-10.015 balances power density with installation flexibility. The motor’s maximum length without holding brake (l) of 246 mm supports integration into space-constrained assemblies.

Performance characteristics are optimized through refined electrical and mechanical design parameters. The locked rotor current (i0) of 14 A ensures robust startup under load conditions, and the moment of inertia, incl. encoder (j) of 21 × 10⁻⁴ kg·m² provides stability during rapid speed changes. High-resolution motion is enabled by the precision/resolution of ±20 angular seconds / 8 million incr./rev., delivering repeatability for precision machining and inspection tasks. Power management for the holding brake is governed by a supply voltage (ubr) of 24 ±10% V with residual ripple 5% and a rated current for holding brake (ibr) of 0.7 A, producing a holding torque (mbr) of 18 Nm at 120°C. The moment of inertia for holding brake (jbr) of 3.1 × 10⁻⁴ kg·m² minimizes additional load on the drive system.

Built for demanding industrial automation, the SF-A4.0091.060-10.015 servo motor offers robust mechanical interfaces and proven reliability. The shaft dimensions (d × L) of Ø24 × 50 mm facilitate smooth power transmission to gearboxes, couplings, and feedback devices. Flange and mounting features conform to DIN standards for simple retrofitting into existing installations, and the optional resolver provides enhanced resilience in EMI-prone environments. Bosch Rexroth Indramat’s stringent quality controls ensure consistent performance across ambient conditions, making this servo motor ideal for robotics, packaging machinery, CNC systems, and other precision motion applications. Integrators benefit from the comprehensive specification set and compatibility with standard drive electronics, reducing time-to-market for complex automation projects.
