SF-A4.0172.060-10.050

The Bosch Rexroth Indramat SF-A4.0172.060-10.050 from the SF Servo Motors series features an integrated STG/MTG encoder and delivers a locked rotor current of 17 A at a rated speed of 6000 rpm. Designed with a Basic Version smooth shaft without a mating connector, this motor streamlines installation while preserving compatibility across the SF-A4 lineup. Its compact 142 mm flange diameter and robust low-contamination aluminum frame material ensure precise alignment and long-term structural integrity. Ideal for high-precision applications, the SF-A4.0172.060-10.050 upholds Bosch Rexroth Indramat’s reputation for reliability and accuracy.

Reliability is assured by a bearing service life of a minimum 20,000 running hours and a frame length not exceeding 309 mm (excluding holding brakes), which optimizes cabinet space. Weighing just 19 kg, this motor strikes an excellent mass-to-torque ratio and minimizes inertia penalties. The rotor’s moment of inertia of 40×10^–4 kgm^2 (including encoder) facilitates rapid response and accurate positioning. A 24 mm × 50 mm cylindrical output shaft transmits up to 18 Nm of torque with minimal backlash.

Operating on a DC 670 V supply and employing a brushless synchronous design based on sinusoidal electromotive force, the SF-A4.0172.060-10.050 requires no external cooling, thanks to its naturally aspirated housing. Integration with Bosch Rexroth’s Servodyn-D inverter system further accelerates commissioning and diagnostics. With its maintenance-free bearings and plug-and-play encoder interface, this servo motor is ideal for demanding automation, robotics, and high-dynamic positioning tasks.
