Product Description:

The SF-A2.0026.030-00.015 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. It is a permanently excited synchronous unit that converts electrical energy into controlled mechanical rotation for positioning and velocity tasks in automated machinery. With a keyed output shaft, it transmits torque to couplings or pulleys, making it suitable for production lines that demand repeatable motion under closed-loop feedback and accurate speed regulation.

Electrical performance is based on a DC link that operates at 670 V, giving the drive sufficient headroom for dynamic torque commands. At its rated operating point, the rotor reaches 3000 rpm, and each delivered ampere produces torque according to a constant of 1.5 Nm/A. Start-up behavior includes a locked-rotor torque of 2.6 Nm and a stall current of 1.7 A, which are relevant when matching the motor with protective devices and drive amplifiers. Heat developed during continuous duty is removed by natural convection, so no external fan or fluid circuit is required, although space around the housing should remain clear for airflow. A single-turn absolute encoder provides position feedback to the controller.

Mechanical integration is aided by a flange that measures 100 mm across, allowing direct attachment to standard gearbox or frame patterns without adapter plates. Service planning is supported by an expected operating life of at least 20,000 hours under nominal load, which helps limit unplanned downtime. Overtemperature events are detected by two NTCs embedded in the stator, so the drive can respond before insulation limits are exceeded. The motor uses a keyway shaft for torque transmission and supports closed-loop operation on positioning and speed-control axes.
