Product Description:

The SF-A0.0008.060-00.008 is a permanent-magnet servo motor produced by Bosch Rexroth Indramat for the SF Servo Motors series. As a drive element in industrial automation, it converts electrical energy into tightly regulated mechanical rotation so that positioning axes and speed-controlled spindles follow command profiles with minimal lag. Electronic commutation eliminates brush wear, and the absolute value encoder supplies single-turn position data directly to the drive controller, allowing immediate reference after power-up without homing routines.

This model draws power from a DC bus rated at 670 V, giving the drive ample voltage headroom for quick torque buildup at its rated speed of 6000 rpm. The back EMF follows a sinusoidal curve, which reduces torque ripple and simplifies current control in the inverter. Heat is removed only through natural convection, so airflow around the motor must not be obstructed. A locked-rotor torque of 0.8 Nm indicates the static load the shaft can hold when stalled without exceeding thermal limits. The motor carries an absolute encoder in the single-turn STG version, giving 360-degree resolution for precise servo loops, and commutation feedback remains valid across the full revolution.

Mechanical integration follows the flange pattern designated IM B5, so it can bolt directly to gearboxes or machinery walls. Acoustic emission peaks at 58 dB(A), permitting installation near operating areas without additional acoustic shielding, and the assembly endures shocks up to 6 g for use on fast-moving gantries or pick-and-place heads. Its minimum service expectancy is 20,000 hours of operation when ambient limits are met. Two integral NTC temperature sensors report winding heat to the drive for derating or shutdown logic, and the electronic commutation scheme remains stable because the motor’s EMF, encoder signals, and thermal data are processed together within the control loop.
