Product Description:

Bosch Rexroth Indramat supplies the SF-A2.0041.060-04.050 as part of its SF Servo Motors series. The device is an electromechanical actuator that delivers precise, repeatable motion for automated test rigs, packaging lines, and small machining centers. By generating commanded torque in response to drive current, the motor closes position and speed loops that are fundamental to coordinated multi-axis industrial automation.

The motor is configured for flange installation according to IM B5, so the housing seats against a driven machine frame while the shaft remains free for couplings. A rated speed of 6000 rpm permits high surface velocities on compact mechanisms, and the torque constant of 0.73 Nm/A gives the relationship between phase current and developed torque for accurate drive tuning. When the axis must hold position at power-off, the integrated brake engages at 24 V DC and provides a static torque of 3.2 Nm to restrain the shaft. The housing carries an IP67 protection rating, so the windings and feedback components stay protected from dust ingress and temporary water immersion on washdown or coolant-splashed assemblies.

The drive is supplied from a 670 V DC link, enabling rapid acceleration without droop. If the shaft is prevented from turning, the winding can safely carry a locked-rotor current of 5.6 A, generating up to 4.0 Nm for short durations while thermal limits are monitored by twin NTC sensors embedded in the stator. Absolute-value encoder feedback preserves position data after shutdown, which shortens homing sequences and makes brake release more predictable. For installations near operators, an acoustic emission of 58 dB(A) meets general plant noise guidelines, and resistance to mechanical impacts of up to 6 g allows the motor to withstand handling shocks during transport.
