Product Description:

The SF-A3.0093.060-10.000 is a servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It is built for closed-loop positioning and speed control in automated machinery, where a compact rotary actuator must follow precise motion commands delivered by a drive controller. This model incorporates a single-turn absolute encoder so the control system can read true rotor position immediately after power-up, eliminating homing moves and shortening machine cycle times. Its layout suits applications that require repeatable starts, stops, and accurate position holding during normal machine operation.

The motor is energized from a DC bus of 670 VDC, allowing high power density while keeping conductor currents moderate. Its mechanical output can reach 6000 rpm, a speed that suits fast indexing tables or spindle duties. Electromechanical conversion efficiency is supported by a torque constant of 0.67 Nm/A, meaning each ampere of phase current produces a predictable amount of torque. Rotor position feedback is delivered with a resolution of 8 million increments per revolution, giving the controller fine interpolation for contouring or electronic gearing. In start-up or stall conditions, the winding may draw a locked-rotor current of 13.5 A. That current level should be considered when matching the motor to a compatible drive amplifier. A smooth Ø19 × 40 mm shaft simplifies coupling to precision hubs, and the overall motor length of 287 mm helps the unit fit into shallow machine spaces.

Static load capability is supported by a locked-rotor torque of 9.1 Nm, which helps the motor resist movement when the shaft is not turning. The motor uses a flange with a diameter of 116 mm, aligning with common servomotor mounting patterns. Dynamic response is aided by a rotor inertia of 16 × 10⁻⁴ kg·m², which helps balance quick acceleration with stable regulation. The housing mass of 12 kg adds structural stability and supports heat absorption during sustained operation.
