Product Description:

The SF-A5.0700.020-00.030 is a rotary servo motor engineered by Bosch Rexroth Indramat and included in the SF Servo Motors series. Designed for closed-loop drive systems, the unit converts electrical energy from a matched inverter into controlled mechanical output for positioning, speed control, and torque control in automated machinery. Its IM B5 construction, 190 mm mounting flange, and keyed 32 mm shaft support direct connection to gearboxes or machine spindles, making it suitable for packaging, material handling, and process equipment where accurate rotary motion is required.

The motor operates from a DC link that can reach 670 V, which matches high-power drive platforms used in industrial motion systems. Rotor position is returned through an encoder with 8,000,000 incr./rev., and its single-turn absolute measuring method allows the drive to know shaft position within one revolution after power is restored. During startup, the stator can draw a locked-rotor current of 34 A and produce up to 69 Nm of stall torque, which helps move heavy loads from rest without hesitation. A rotor inertia of 257 × 10⁻⁴ kg·m², dual NTC temperature sensors, and a keyway shaft with feather key support stable acceleration, temperature monitoring, and secure torque transmission during repetitive motion.

The unit weighs 50 kg, so the machine structure must support both the motor body and the overhung load created by the coupling arrangement. The housing has IP67 protection except at the output side, which helps keep dust and temporary immersion away from the main enclosure while leaving the shaft end dependent on the connected mechanical interface. Under continuous duty, the motor runs at a rated speed of 2000 rpm, and it delivers approximately 2.0 Nm/A of torque per ampere. These operating values suit conveyors, presses, and forming equipment that require repeatable motion with steady thermal performance over long production cycles.
