Product Description:

The SF-B4.0230.030-14.056 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It functions as a rotary actuator that converts controlled electrical energy into precise mechanical motion for positioning tasks in industrial automation lines, such as gantry axes or packaging stations. By integrating an absolute encoder, the motor can report position data even when power is off, eliminating homing cycles at startup and improving overall cycle efficiency.

Under rated conditions, the rotor turns at 3000 rpm, and each ampere delivered to the stator generates 1.57 Nm/A of electromagnetic torque. When power is first applied, the motor can accept a locked-rotor inrush of 14 A; this current corresponds to a locked-rotor torque of 22 Nm that helps overcome static friction in the load train. A permanent-magnet holding brake is integrated and releases when a control signal supplies 24 VDC at 0.7 A; the brake supplies a resisting moment of 18 Nm and has an inertia contribution of 3.1 × 10⁻⁴ kg·m². Power conductors are routed through a size 1.5 circular connector, while the brake circuit uses a separate cable so the two circuits can be routed independently.

The motor housing carries a square mounting interface with a flange dimension of 142 mm, and the steel rotor has an inertia of 54 × 10^-4 kg·m², balancing dynamic response against load-side stability. Output torque is transferred through a precision-ground shaft that measures Ø24 × 50 mm, and the geometry aligns with standard couplings while minimizing radial runout. To handle continuous current without overheating, the stator leads rely on a dedicated feeder of 4 × 4.0 mm² cross-section, while the separate brake leads reduce electromagnetic interference with feedback signals.
