Product Description:

The SF-A3.0068.030-10.015 is a permanent-magnet synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SF Servo Motors series. It is intended for closed-loop industrial axes where precise torque, speed, and position control are required, such as indexing tables, gantry drives, and packaging stations. When connected to a matching drive controller, the unit translates regulated current into rotor motion so programmable automation equipment can follow commanded movement profiles. Its synchronous design helps the drive maintain accurate rotor position while responding quickly to command changes and load disturbances. That makes it suitable for coordinated axes that must start, stop, reverse, and settle without excessive lag.

Its electrical interface uses a DC link that operates at 670 V, providing the energy reserve for acceleration and dynamic braking. If the shaft is prevented from turning during start-up, the windings accept 5.0 A of locked-rotor current and produce 6.8 Nm of locked-rotor torque to help the axis overcome static friction. With normal rotation, the motor reaches a rated speed of 3000 rpm, which balances continuous output with thermal limits during sustained operation. The torque constant of 1.36 Nm/A shows how much torque is produced for each ampere supplied by the controller, making current-based control straightforward to scale through the drive. That behavior is useful on axes that must start under load or recover speed quickly after short dwell periods.

During operation, the sound pressure stays below 58 dB(A) Max, which helps limit noise around nearby equipment. The housing withstands shocks up to 6 g, helping protect internal alignment during transport or machine movement. The stator contains 2 NTC sensors that report winding temperature to the inverter so overheating can be detected early and protective shutdown can be applied when needed. Because the thermal feedback is built into the motor, the drive can react to rising winding temperature without relying on external sensors or added wiring.
