Product Description:

The SF-A4.0172.030-14.053 is a servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for industrial automation axes that require precise speed and position control, and it includes an integrated holding brake to secure the load when the system is not driving the shaft. In a matched drive system, the motor converts electrical power from a servo amplifier into mechanical rotation for packaging stations, pick-and-place modules, printing cylinders, and similar motion tasks. The IM B5 mounting arrangement allows direct face mounting to a machine plate or gearbox input, which helps support compact mechanical layouts.

The holding brake is energized with 24 VDC and draws 0.7 A, and that current releases the brake so the rotor can turn. When power is removed, the brake clamps the shaft with 18 Nm of static torque, which helps prevent unwanted movement at standstill. Locked-rotor current can reach 13 A during startup, and under normal operation the rotor reaches a rated speed of 3000 rpm for repeatable cycle timing. The brake mass is 1.04 kg, and the added inertia of 3.1 × 10⁻⁴ kg·m² should be considered when setting acceleration and deceleration behavior. The brake supply can tolerate a ripple of 5%, which helps avoid chatter during brake release.

Mechanical resilience is supported by a shock rating of 6 g, allowing the motor to withstand routine handling and machine vibration with reduced risk of damage. The electromagnetic circuit has a torque constant of 1.38 Nm/A, so commanded current produces a predictable torque response at the shaft. Continuous duty is permitted at ambient temperatures up to 40 °C, which suits typical indoor industrial installations. Acoustic emission does not exceed 58 dB(A), helping the motor fit applications where enclosure noise must remain controlled. These operating values are useful when the motor is installed in closely spaced multi-axis equipment with limited room around each axis.
