Product Description:

The SF-A2.0041.030-10.050 is a brushless servo motor engineered by Bosch Rexroth Indramat within the SF Servo Motors series. It delivers closed-loop rotary motion for positioning axes, feed drives, and ancillary tasks in automated machinery. The motor pairs with Indramat digital drives to convert electrical commands into proportional torque and speed, providing precise acceleration profiles and repeatable stops for pick-and-place gantries, packaging lines, and CNC tool changers. Its brushless design supports responsive motion control in machines that require frequent starts, stops, and direction changes.

The stator housing follows the IM B5 flange-mount format, and the front mounting face is sized at 100 mm, so the motor seats directly on standardized gearboxes or machine frames. Rated mechanical output occurs at 3000 rpm, allowing moderate spindle or conveyor velocities without extra gearing. A torque constant of 1.43 Nm/A links drive current to generated torque. During stall or initial energization, the windings can accept 2.8 A of locked-rotor current. Heat is removed by radiation and natural convection, eliminating the need for forced air or liquid cooling. The sinusoidal back-EMF profile supports smooth servo control with the absolute value encoder.

At standstill, the motor can resist a static load torque of 4.0 Nm, helping prevent unintended movement while the control system synchronizes. Audible output is limited to 58 dB(A), which helps keep operating noise low. Thermal behavior is monitored by two NTCs embedded in the stator windings, and these sensors provide temperature feedback to the drive controller. Mechanical shocks up to 6 g are tolerated, allowing use on moving carriages or end effectors subject to sudden stops. The motor is supplied without a mating connector, so the connection style can be selected to match the application.
