Product Description:

The SF-A2.0013.060-14.050 is a brushless servo motor produced by Bosch Rexroth Indramat in the SF Servo Motors series. It is intended for compact automation axes that require precise positioning and high repeatability, delivering commanded shaft motion under digital drive control. The motor links to the controller through an integrated absolute encoder for immediate position feedback, and its built-in electromagnetic brake secures loads whenever power is removed. This supports vertical axes, indexing mechanisms, and other applications that need stable position holding after motion stops.

At a rated speed of 6000 rpm, the motor supports rapid-cycle machinery without sacrificing accuracy. The associated power stage operates from a DC link of 670 V, so winding insulation and connectors are sized for that voltage class. Each ampere supplied produces 0.76 Nm/A of torque, enabling straightforward current-based force control. Position data are provided by an absolute encoder with a resolution of 8 million increments per revolution and an accuracy of ±20 arcseconds, allowing sub-arc-minute moves without external transducers. The feedback channel also allows the drive to detect actual shaft position immediately after startup.

The holding device resists motion with 3.2 Nm of torque and is energized by a nominal 24 VDC supply, keeping control wiring consistent with common safety circuits. Dynamic response is aided by a rotor inertia of 2 × 10⁻⁴ kg·m², permitting quick acceleration and fast direction changes while limiting drive current peaks. If motion is blocked, the unit can tolerate a locked-rotor torque of 1.3 Nm while drawing up to 1.7 A for short periods, helping prevent thermal overload during jam conditions. A mating connector is not included, so cable assemblies can be selected to match shielding, length, and bend-radius requirements for the installation.
