Product Description:

The SF-A4.0230.030-10.015 is a permanent-magnet motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. The model delivers closed-loop velocity and torque control for positioning tables, pick-and-place axes, and other industrial automation loads that require repeatable motion profiles. It integrates an absolute encoder so the drive controller knows rotor position after power-up and can begin controlled motion without a homing cycle. This helps the axis return to commanded motion quickly after a power interruption or a controlled stop. Balance quality in grade N keeps vibration within normal limits for high-cycle equipment.

In operation, the motor reaches a rated mechanical speed of 3000 rpm, allowing synchronous drive systems to match standard linear feed rates without gearing. A torque constant of 1.57 Nm/A links current command to shaft torque, giving the controller a predictable gain for servo loop tuning. The mounting interface follows the IM B5 pattern, and its circular flange measures 142 mm, so it mounts directly to standardized gearboxes or machine plates. This face-mount arrangement helps keep shaft alignment consistent when the motor is coupled to driven equipment. The housing is rated IP67 (except output flange), which protects the main body against dust ingress and temporary water exposure while leaving the flange open for accurate centering.

At standstill, the motor provides a locked-rotor torque of 22 Nm and draws a stall current of 14 A, showing the available static output before rotation begins. The motor uses a smooth shaft sized at Ø24 × 50 mm, which supports backlash-free couplings such as clamp collars or shrink discs. Two integrated thermistors listed as 2 × NTC send winding temperature data to the drive so thermal limits can be monitored during operation. The plug-in output and brake connector keeps wiring orderly and makes connection points easier to access. The connector also separates external wiring from the shaft area, which helps keep cable routing more orderly around the motor.
