Product Description:

The SF-A2.0026.060-10.050 is a servo motor produced by Bosch Rexroth Indramat in the SF Servo Motors series. Designed for closed-loop motion axes in industrial automation, it converts electrical commands from a drive into controlled mechanical rotation. This supports precise positioning and stable velocity control in pick-and-place, printing, and handling equipment. Its role is to provide smooth axis motion when the control system must coordinate acceleration, deceleration, and dwell periods with high repeatability. The motor is suited for machines that require repeatable starts, stops, and direction changes during continuous operation.

Electrical integration is based on a direct current link rated at 670 V, allowing the drive to draw energy from high-voltage inverters without an intermediate transformer. Mechanical attachment uses a 100 mm square flange that conforms to the IEC 72-2 / DIN 42948 pattern, so the housing fits standardized machine plates. At standstill, the rotor can be energized up to 3.5 A and produces a locked-rotor torque of 2.7 Nm. The stator uses IM B5 construction, and heat leaves the windings through radiation and natural convection, so no forced-air or liquid cooling circuit is required.

During operation, the motor reaches a rated speed of 6000 rpm while keeping acoustic emissions at 58 dB(A). It tolerates brief mechanical shock up to 6 g, which helps the motor handle rapid indexing and short impact loads. Dynamic torque production follows a constant of 0.78 Nm/A, allowing the control loop to relate motor current to output torque with predictable response. Two integrated NTC temperature sensors report winding temperature directly to the drive, allowing thermal limiting without external probes. This helps protect the motor during demanding duty cycles and supports stable operation when load conditions change quickly.
