Product Description:
Bosch Rexroth Indramat manufactures the SF-B5.0250.030-10.050 in its SF Servo Motors series. The unit is a frameless B5 servo motor that supplies closed-loop motion for indexing tables, coordinated axes, and other automation modules where accurate torque delivery and repeatable speed control are required. It links a digital drive to mechanical loads by translating commanded current profiles into precise shaft rotation. This arrangement supports stable axis response during frequent starts, stops, and direction changes in industrial equipment.
The motor develops a standstill torque of 25 Nm while drawing a standstill current of 16.1 A. During motion, a rated speed of 3000 rpm allows the axis to meet typical production throughput targets, and the electromagnetic design yields a torque constant of 1.44 Nm/A, indicating how much torque is produced for each additional ampere of phase current. Rotor dynamics are influenced by an inertia of 83 ×10-4 kg·m², which supports responsive acceleration while helping smooth brief load disturbances. These electrical and dynamic values make the motor suitable for controlled positioning and repeatable speed regulation.
The motor has a mass of 24 kg without a brake, and the housing length stays within 300 mm for installation in compact machine frames. Power and feedback reach the stator through a size 1.0 connector and a motor cable rated at 4 × 2.5 mm², which helps keep conductor heating within normal limits over typical cable runs. The IM B5 mounting arrangement uses a 180 mm pilot diameter, and the shaft has a diameter of 32 mm with a keyed 58 mm projection for couplings. Two NTC temperature sensors embedded in the windings report thermal status to the drive so current can be limited before overheating occurs.
