Product Description:
The SF-B4.0230.060-10.050 servo motor is built by Bosch Rexroth Indramat as part of the SF Servo Motors series. It is a synchronous, electronically commutated drive component intended for closed-loop motion axes in automated machinery. By coupling directly to a servo amplifier, the unit supplies controlled torque and speed so that pick-and-place heads, winding stations, and other production modules can execute repeatable linear or rotary movements without mechanical backlash.
The motor operates from a DC link potential of 670 V, giving the drive electronics a wide voltage margin for dynamic acceleration profiles. At its rated mechanical velocity of 6000 rpm, the rotor can track rapidly changing command signals while staying within thermal limits. A torque constant of 0.88 Nm/A links drive current to shaft torque, allowing the controller to calculate the required current for a given load. During a stall condition, the shaft can sustain 22 Nm, indicating the static holding capability before motion begins. Position feedback is provided by an absolute-value encoder, which returns a unique digital position each revolution so the control system always knows the true rotor angle after power-up.
Additional characteristics complete the performance profile. A locked-rotor current of 25 A is the peak electrical draw the amplifier must deliver during startup or jam events. The housing tolerates shocks up to 6 g, supporting installation on equipment that experiences rapid index stops or tool impacts. Internal thermal protection is handled by 2 NTCs that report winding temperature to the drive for derating or shutdown. The motor has a smooth shaft for backlash-free coupling with precision clamping hubs, and no mating connector is included so cabling can be selected for the application.
