Product Description:
The SF-A4.0125.030-10.070 is a brushless servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. Serving as an electromechanical actuator, it converts drive current from digital controllers into precise rotary motion for industrial positioning tables, packaging axes, and pick-and-place heads. Its integrated optical encoder feeds high-resolution position data back to the drive, allowing closed-loop speed and torque regulation that is critical for repeatable automation tasks. The motor’s construction supports sealed operation in harsh washdown zones common to food or chemical lines.
At nominal conditions, the rotor stabilizes at 3000 rpm, which is its rated continuous operating speed when driven by a matched inverter. Produced torque is proportional to phase current through a constant of 1.37 Nm/A, giving the controller a straightforward relationship for current loop tuning. During startup or a sudden jam, it can withstand a locked-rotor torque of 14.5 Nm while drawing 10.6 A; these limits protect mechanical couplings and the power stage. Dynamic behavior is shaped by a rotor inertia of 30 × 10⁻⁴ kg·m², enabling rapid acceleration without excessive overshoot. Position feedback is supplied by an 8-million-increment encoder with ±20-arcsecond precision for micron-level repeatability.
A square flange of 142 mm permits direct mounting to geared reducers or linear modules, while the overall body length is 277 mm, allowing compact installation inside tight cell enclosures. The output shaft measures Ø24 × 50 mm and is supplied with a keyway to transmit rated torque without slip. Electrical and feedback conductors exit through a single 6-pin motor connector, simplifying cable management on articulated axes. With a mass of 16 kg, the unit adds manageable static load to vertical slides yet provides enough thermal mass for stable temperature rise. An enclosure classification of IP67 keeps internal windings isolated from coolant splash and airborne particulates encountered on machining centers.
