Product Description:
The SF-A5.0460.030-04.050 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. This AC servo motor converts electrical power from a DC bus into controlled rotary motion for positioning, indexing, and speed regulation in automated machinery. With an electromechanical holding brake and digital feedback, SF-A5.0460.030-04.050 supports axes that must remain secure during power loss while continuing to provide shaft position data to the drive controller. That combination suits applications that require accurate starts, stops, and stable holding at standstill.
At its rated operating point, the motor reaches a speed of 3000 rpm, enabling direct coupling to gearless axes that demand rapid cycle times. A torque constant of 1.58 Nm/A links stator current to produced torque and supports current-loop scaling in the drive. The square mounting flange measures 190 mm, providing a clear reference for face-mount drilling patterns. During braking sequences, an internal friction element sustains 56 Nm of holding torque so vertical loads remain stationary without external clamps. When supplied from a DC bus of 670 VDC, the windings operate within their linear back-EMF range, so rated speed is available without field weakening.
The brake coil is energized from 24 VDC, and it draws a steady 1.33 A while released, matching common control power supplies. To overcome static friction at startup, the electrical design permits a locked-rotor current of 29 A, delivering a stall torque reserve of 46 Nm before motion begins. Two NTC temperature sensors monitor rotor heating during these transients, allowing the controller to reduce duty if winding temperature rises too far. This added thermal monitoring is useful in repeated starts, short indexing moves, and frequent brake cycles.
