Product Description:
The SF-A4.0230.030-10.071 is a servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. It is intended for closed-loop industrial automation where precise torque and speed regulation are required to position or drive machine axes. The motor converts electrical energy into controlled mechanical rotation, allowing integration with Rexroth drive controllers in packaging machines, material-handling systems, and assembly lines.
This model operates from a DC link that is rated at 670 V, giving the drive stage a wide margin for regenerative events during deceleration. At its rated operating point, the rotor turns at 3000 rpm, which matches common servo drive gear ratios without overspeeding connected mechanical elements. During a stall, the motor can develop a holding torque of 22 Nm, and the corresponding locked-rotor current reaches 14 A; these values help with inverter sizing for startup and static load conditions. Continuous torque buildup is proportional to phase current through a torque constant of 1.57 Nm/A, which supports linear current-to-torque mapping in the control loop. Electrical power is supplied through a size-1, 6-pin motor connector that routes phase conductors and encoder lines in a single housing.
The mechanical interface uses a flange diameter of 142 mm, supporting installation within the SF series frame family. Dynamic response is influenced by a combined rotor and encoder inertia of 54 × 10⁻⁴ kg·m², balancing acceleration capability with load stability during indexing and speed changes. Power conductors are specified as 4 × 2.5 mm² motor cables, allowing voltage-drop control over typical cabinet-to-axis distances. Thermal monitoring is provided by 2 × NTC sensors embedded in the stator windings, giving the controller real-time temperature data for overload protection and derating.
