Product Description:

The SF-A2.0041.060-10.053 belongs to the SF Servo Motors series produced by Bosch Rexroth Indramat. It is a permanent-magnet synchronous servo motor for closed-loop speed and torque control. The unit is suited for positioning tables, pick-and-place axes, and similar automation tasks that require repeatable motion profiles in a compact installation space. This operating style supports fast starts, controlled stops, and stable response during repetitive machine cycles.

Its rated speed reaches 6000 rpm, allowing high linear travel rates when the motor is coupled to finely pitched mechanical transmissions. Each ampere delivered by the drive electronics generates about 0.73 Nm/A, a torque constant that simplifies current scaling during dynamic moves. When the shaft is locked, the windings can accept 5.6 A and deliver a stall torque of 4.0 Nm. A DC bus of 670 V supports rapid acceleration because the higher link voltage increases the available back-EMF ceiling. Rotor inertia is limited to 6×10⁻⁴ kg·m², so the servo responds quickly to command changes without excessive overshoot during short-stroke indexing or multi-axis synchronization.

The motor can handle an axial load of 70 N, accommodating belt tension or vertical screw preload without auxiliary thrust bearings. It can also withstand shocks up to 6 g during installation on moving gantries, and airborne sound pressure remains below 58 dB(A). Heat from the stator dissipates through radiation and natural convection, so no forced-air or liquid cooling hardware is required. Two integrated NTC sensors report winding temperature for real-time overload protection, and a 1.0 Ω plug-in brake resistor can be connected to redirect regenerative energy during deceleration. The motor follows the IM B5 flange-mount construction code, which helps simplify alignment in compact machine frames.
