Product Description:

The SF-B5.0460.020-14.018 is a servo motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. Designed for closed-loop positioning and velocity tasks, this motor converts electrical drive output into precisely controlled mechanical motion for axes on packaging, handling, or machining lines. Its construction follows the IM B5 mounting style, allowing flange installation in equipment frames while keeping the shaft free for couplings or gearheads. An integrated permanent-magnet holding brake prevents drift when power is removed, helping the axis stop reliably during automated cycles.

The motor has a rated speed of 2000 rpm, which is its continuous operating velocity under nominal load. Dynamic behavior is influenced by a motor inertia of 166 ×10⁻⁴ kg·m², and this moderate rotor mass balances quick acceleration with smooth running. When the brake is engaged, it can sustain a load with 56 Nm of static torque, and it releases reliably once the coil is supplied with the specified 1.33 A. The brake coil is energized by a control circuit that supplies 24 VDC, which is a common voltage on low-power machine safety rails. Brake inertia is 30 ×10⁻⁴ kg·m², which adds to the overall rotating mass but remains low enough to support responsive motion. The permanent-magnet brake reduces wear during frequent start-stop duty.

Under locked-rotor conditions, the shaft can deliver 46 Nm of torque while the winding draws up to 21 A. The electromagnetic coupling converts each ampere into torque with a torque constant of 2.2 Nm/A, which supports predictable current-loop behavior. Mechanical ruggedness is shown by shock resistance to 6 g, allowing installation on mobile or vibration-prone platforms. Acoustic emission does not exceed 58 dB(A), which supports use in noise-sensitive work zones. The permanent-magnet brake keeps holding force available without continuous power during extended dwell periods.
