Product Description:
The SF-B5.0250.020-10.050 is an AC servo motor manufactured by Bosch Rexroth Indramat in the SF Servo Motors series. It serves as a rotary actuator that converts controlled current from a drive into precise shaft movement for indexing, positioning, and coordinated motion in automated machining centers and material-handling equipment. An integrated absolute encoder allows the control system to read exact rotor position immediately after power-up, eliminating the need for a homing cycle and supporting uninterrupted closed-loop operation. This arrangement helps the axis resume commanded motion quickly after startup and supports applications that depend on repeatable position tracking.
Positional feedback is generated at a resolution of 8 million increments per revolution, and its angular accuracy is rated at ±20 arcsec. These values support tight registration in applications such as printing and pick-and-place systems where small position errors can affect part placement or process quality. Mechanical attachment uses a square 190 mm flange, and the output shaft measures 32 mm in diameter by 58 mm in length for standard keyed couplings. The motor reaches its nominal speed at 2000 rpm, while the electromagnetic design provides a torque constant of 2.3 Nm/A, giving the drive predictable torque output per ampere of phase current. During stall conditions, the windings draw locked-rotor current that should be considered when matching the motor to a compatible amplifier, and the overall length of 300 mm helps when installation depth is limited.
The combined rotor and encoder inertia equals 83×10⁻⁴ kg·m², which affects acceleration response and servo loop behavior. For breakaway demands, the unit can supply a locked-rotor torque of 23 Nm, helping the axis overcome static friction at startup and during low-speed transitions. Structural durability is supported by a shock tolerance of 6 g, which is useful in systems exposed to abrupt motion changes or impact loading. A total mass of 24 kg adds thermal capacity during continuous operation and should also be considered when designing the mounting structure and any moving support members.
