Product Description:
The SF-B4.0125.060-14.050 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. In automation cells, the unit converts electrical drive commands into mechanical rotation for axes that demand fast indexing and repeatable positioning. Its integrated holding brake, high-resolution feedback, and standardized flange simplify mounting to gearboxes or direct-drive couplings while letting a controller manage start, stop, and hold functions without additional external hardware. This arrangement suits packaging equipment, transfer mechanisms, and other compact motion systems that require accurate positioning through repeated operating cycles.
The motor reaches a rated speed of 6000 rpm and delivers torque in proportion to current thanks to a torque constant of 0.71 Nm/A. Dynamic response during acceleration is supported by the rotor inertia of 30 × 10-4 kg·m², so command changes are followed quickly without excessive overshoot. When the shaft is locked, the drive may draw up to 17 A, generating the specified locked-rotor torque for short-term stall conditions. The brake circuit operates from a supply of 24 VDC, and its cable pair with 1.5 mm² conductors keeps voltage drop low over typical cabinet runs. An optical encoder with 8 million increments per revolution feeds high-resolution position data back to the drive, supporting precise motion control during rapid starts, stops, and direction changes.
The square flange measures 142 mm, providing a common bolt circle for modular machine frames. During power-off holding, the brake supplies 18 Nm of static torque so vertical loads remain stationary. Power conductors use a 4 × 2.5 mm² motor cable, and the assembled motor length including the brake is 324 mm. Overall mass is 17.7 kg, which adds damping in high-speed assemblies without overstressing mounting plates. A ground steel shaft with a diameter of 24 mm and a working length of 50 mm transmits torque, while a brake rated current of 0.7 A keeps coil heating within limits during extended clamping. The shaft surface also supports secure coupling alignment in applications where smooth power transfer and stable braking are both required.
