Product Description:

The SF-A5.0460.020-10.015 is a drive motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. In automated cells this motor supplies regulated torque and speed to linear actuators, rotary indexers, and handling axes, enabling repeatable motion profiles that match tight cycle-time requirements. It serves as the electromechanical link between the power electronics of a servo drive and the mechanical load that must be positioned or accelerated.

Its rated operating speed of 2000 min⁻¹ defines the maximum continuous shaft velocity that can be reached without derating. When the rotor is locked during commissioning or emergency stops, the motor can deliver a stall torque of 46 Nm, and the drive must be able to supply a stall current of 21 A to reach that value. A flange width of 190 mm aligns with standard mounting patterns, while the housing mass of 35 kg influences gantry sizing and installation tooling. The 180 mm pilot diameter centers the frame, an M12 center hole thread provides a secure lifting eye, and the smooth Ø32 × 58 mm shaft permits direct coupling without a key. Overall body length is 383 mm, ensuring adequate winding space while maintaining a compact footprint.

Dynamic behavior is characterized by a torque constant of 2.2 Nm/A, meaning each ampere of phase current produces that amount of electromagnetic torque. Acceleration capability is tempered by a rotor inertia of 166 × 10⁻⁴ kg·m², a value that balances responsiveness with load stability. Thrust screws or belt drives may apply up to 380 N of axial force without exceeding bearing limits, and the assembly tolerates shocks up to 6 g during transport or machine crashes. These mechanical limits, combined with the smooth shaft style and 6 g shock resistance, allow the motor to interface with precision couplings and maintain alignment under dynamic loading.
