Product Description:

The SF-B5.0460.020-00.106 servo motor is built by Bosch Rexroth Indramat as part of the SF Servo Motors series. Serving as a rotary actuator, it interfaces with a compatible drive to supply closed-loop torque and position for automated machinery such as palletizers, gantry axes, and indexing tables. This arrangement allows the motor to support controlled acceleration, steady-speed operation, and accurate stopping in automated motion systems.

The motor reaches a rated speed of 2000 rpm, allowing moderate-velocity motion profiles without overspeeding standard mechanical transmissions. During startup, a locked-rotor torque of 46 Nm is available, so the axis can overcome static friction or seated loads before rotation begins; this output is produced at a locked-rotor current of 21 A. Electromagnetic conversion is characterized by a torque constant of 2.2 Nm/A, which indicates the torque produced for each ampere delivered by the drive. Position and velocity are reported by a single-turn absolute STG encoder that offers 8 million increments per revolution. Its ±20 arc-second accuracy supports fine contouring when used with high-resolution motion controllers. The motor uses a size 1.5, 8-pin connector that groups power, signal, and protective earth in one locking shell.

The allowable axial load on the shaft is 380 N, so thrust from couplings or belt tension stays within the bearing limit. Dynamic response is influenced by a rotor inertia of 166 × 10⁻⁴ kg·m², which balances quick acceleration with smooth control. Without a holding brake, the unit weighs 35 kg and measures 383 mm in length. The ground steel shaft is sized at Ø32 × 58 mm and is supplied in a keyway configuration that matches the included feather key A10 × 8 × 50 for positive torque transmission. A square mounting face of 190 mm conforms to IEC dimensions, allowing the motor to bolt directly to standard gearboxes or machine frames.
