Product Description:
The SF-A4.0172.030-04.050 is a synchronous servo motor produced by Bosch Rexroth Indramat and supplied within the SF Servo Motors series. It operates with a digital inverter in a servodrive system to move mechanical loads along programmed motion profiles, giving the axis controlled acceleration, deceleration, and steady running speed. Designed for closed-loop positioning and velocity control, the motor converts drive commands into precise shaft rotation for pick-and-place units, packaging axes, machine tool feeds, and other automated equipment that depends on repeatable motion.
Mechanically, the motor withstands an axial load of 154 N, allowing direct coupling to ball screws without additional thrust bearings; this admissible thrust margin helps protect the encoder bearings during continuous feed operation. An electromechanical holding brake provides 18 Nm of static torque to secure vertical axes, and it is operated from a 24 VDC supply. During startup, the windings can draw a locked-rotor current of 13 A, which is relevant for drive sizing, fuse selection, and conductor selection during system integration. The housing follows the IM B5 construction pattern with a mounting flange that measures 142 mm in diameter, and an absolute encoder is integrated for single-turn position feedback.
The shaft reaches a rated speed of 3000 rpm, and the magnetic circuit yields a torque constant of 1.38 Nm/A, so motor current produces torque in a predictable relationship across normal servo operation. Sealing to IP67 helps keep out dust and allows temporary immersion, while resistance to shocks of 6 g supports use on machinery exposed to transport loads or intermittent impacts. Two NTC thermal sensors monitor stator temperature so the drive can respond to heat buildup before it affects winding insulation or positioning stability.
