Product Description:
The SF-A4.0172.030-10.152 is a servo motor manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. Designed for closed-loop motion control, it transforms the regulated output of a Rexroth drive into precise rotary movement for pick-and-place axes, packaging stations, and general automation equipment. Its built-in absolute encoder supplies position data after power cycles without relying on retained incremental counts. The housing follows the IM B5 construction style, allowing the unit to bolt directly to a gearbox or machine wall without additional brackets. This flange arrangement also provides a direct path for grounding the motor housing through the machine frame.
The stator is wound for a DC bus voltage of 670 V, allowing high power density while keeping link current low. The nominal operating speed reaches 3000 rpm, making the motor suitable for positioning axes that require rapid movement. Its torque constant is 1.38 Nm/A, indicating the amount of torque produced for each ampere supplied by the drive. At standstill, the motor can tolerate a locked-rotor current of 13 A and generate a stall torque of 18 Nm; these values can be used when setting the drive’s current limits. Two internal NTC sensors monitor motor temperature and signal an overtemperature condition to the controller. A separate mating connector is not included with the motor, but the motor-side connector is size 1 and supports compatible standard cabling.
The mounting interface has a diameter of 142 mm, providing a broad contact surface for stable attachment to the driven equipment. The shaft withstands an axial load of up to 154 N without compromising alignment during operation. The bearings provide more than 20,000 hours of service under the applicable operating conditions. The assembly can absorb shocks as high as 6 g during emergency stops or transportation. Running noise does not exceed 58 dB(A), supporting installation near operator-accessible areas where motor noise must remain controlled. The permitted ambient vibration level is compatible with the stated flange, shaft, and bearing capabilities for industrial machinery.
