Product Description:

The SF-A2.0020.030-10.050 synchronous servo motor is manufactured by Bosch Rexroth Indramat for the SF Servo Motors series. It employs electronic commutation to deliver controlled torque and speed in automated equipment such as gantry axes, tool changers, and packaging stations. The motor converts DC bus energy into rotary motion with a sinusoidal back EMF pattern that supports precision vector control. By integrating a sealed stator and compact rotor assembly, it provides a space-saving solution for motion tasks that demand accurate positioning and repeatable cycle times. Its compact format also supports machine layouts where responsive servo motion is needed without a large motor envelope.

Under rated operating conditions, the shaft turns at 3000 rpm while the connected inverter maintains a DC link voltage of 670 V. The electromagnetic design produces torque in direct proportion to phase current through a constant of 1.5 Nm/A, which simplifies controller current loops. If the rotor is restrained, the motor can apply a locked-shaft torque of 2.0 Nm. This condition corresponds to a locked-rotor current of 1.3 A, which helps set overcurrent thresholds during startup. The sinusoidal electromotive force supports smooth acceleration with minimal cogging, and the electronic commutation synchronizes phase excitation to maintain efficiency across the full speed range.

The housing carries an IP67 protection rating, allowing operation in washdown zones and dusty conveyor lines. Thermal energy is dissipated by natural convection, eliminating ancillary blowers and reducing maintenance. Acoustic emission is limited to 58 dB(A) at full load, which helps keep nearby machine areas quieter during continuous operation. The mechanical structure withstands impacts up to 6 g, supporting reliable service on mobile or vibration-prone platforms. The sealed housing and passive cooling arrangement also suit installations where added airflow equipment is not practical.
