Product Description:

Bosch Rexroth Indramat manufactures the SF-A4.0230.030-10.030 servo motor as part of the SF Servo Motors series. The unit is a brushless, permanently excited synchronous motor intended for closed-loop industrial automation. In multi-axis machining centers, pick-and-place gantries, and material-handling lines, it converts electrical command signals into synchronized shaft rotation. This operating principle supports accurate load positioning and reduces the maintenance associated with brushed motor designs. It is suited to applications that require repeatable starts, stops, and coordinated axis motion across frequent duty cycles.

During startup, the motor can draw a locked-rotor current of 14 A and produce a locked-rotor torque of 22 Nm, which helps break static friction in a loaded axis. This starting capability is useful when a mechanism must begin moving from rest under load without assistance from external gearing. At a rated speed of 3000 rpm, the electromagnetic circuit develops torque in proportion to a torque constant of 1.57 Nm/A, allowing the drive to relate commanded current to motor output in a direct way. Continuous heat is dispersed through a housing length of 341 mm, which provides surface area for convection and fits typical panel layouts with moderate installation depth.

The rotating assembly has a rotor inertia of 54 × 10⁻⁴ kg·m², which balances acceleration response with vibration damping when the motor is coupled to light indexing tables or similar loads. That inertia level helps the axis respond quickly while still remaining mechanically stable during direction changes. The output shaft measures 24 mm in diameter and 50 mm in axial extension, supporting standard keyway hubs for belts, pulleys, and planetary gearheads. These shaft dimensions allow common mechanical connections without requiring unusually long couplings or excessive overhang at the drive end.
