Product Description:
The SF-A2.02.0020.030-00.050 is produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. Designed for industrial automation, the unit converts the regulated output of a Rexroth drive into controlled rotary power that can position, index, or synchronize machine elements. It interfaces to the system through a high-voltage DC bus and a front-flange housing, providing a compact solution for axes where repeatable motion is required. It is suited for machinery that depends on consistent closed-loop motion during positioning and synchronized movement.
During continuous duty, the shaft reaches a rated speed of 3000 rpm, giving the controller a wide velocity range before field weakening. The electromagnetic design delivers a torque constant of 1.5 Nm/A, so each ampere in the windings produces predictable load-side torque. At standstill, the motor can accept a locked-rotor current of 1.3 A and deliver a locked-rotor torque of 2.0 Nm. These values help determine current demand during startup and low-speed operation. The associated drive feeds the motor from a DC link of 670 V, allowing low phase current for reduced copper loss. Two integrated NTC sensors report winding temperature, and the mechanical build uses the IM B5 flange format.
Heat leaves the housing by radiation and natural convection, eliminating the need for forced ventilation in standard cabinets. Under maximum load, the sound pressure does not exceed 58 dB(A), which supports installation near operating areas. The stator and enclosure withstand impacts up to 6 g, so transport shocks or mobile-axis accelerations will not compromise alignment. Power exits through a circular connector equipped with 6 pins, and the matching plug is not included with the motor. Separate leads are provided for the two NTC sensors, and the power connection accepts a four-core 1.5 mm² cable intended for this motor type.
