Product Description:

The SF-A3.0042.030-14.037 is a servo motor manufactured by Bosch Rexroth Indramat within the SF Servo Motors series. It is intended for precision positioning in industrial automation cells, where closed-loop drives convert electrical input into repeatable rotary motion for tooling, conveyor, or pick-and-place axes. Its permanent-magnet rotor and sealed bearings support reliable operation in compact machinery. The IM B5 flange arrangement allows direct coupling to the driven equipment while keeping the overall motor envelope minimal.

During continuous rotation, the motor reaches a rated speed of 3000 rpm. This rated speed marks the normal upper operating point before overspeed reserve is used. A torque constant of 1.6 Nm/A links drive current to output torque, enabling linear controller scaling. When power is removed, the integral brake can sustain a static holding torque of 10.0 Nm, which helps prevent back-driving on vertical axes. The housing carries an enclosure rating of IP67, which blocks dust ingress and temporary immersion. Acoustic emissions stay below 58 dB(A), helping reduce machine-area noise during operation. In the IM B5 construction form, the flange faces the driven equipment, which helps reduce alignment errors. Locked-rotor current is 2.3 A and the corresponding stalled torque is 3.7 Nm, which are useful values for sizing fuses and overload relays.

The integrated brake uses a supply of 24 VDC and requires only 0.66 A to energize, which keeps the demand on the machine's low-voltage bus modest. Brake inertia is 1.06 × 10^-4 kg·m², and brake mass is 0.6 kg, so the added brake hardware does not introduce excessive rotational load. The motor withstands impacts up to 6 g, and an admissible axial force of 133 N helps protect the bearings when pulleys or lead screws apply thrust. This impact tolerance and axial load capacity support rapid index cycles in washdown or outdoor sections of an automated line. The sealed bearing arrangement also helps the motor remain suitable for installations where moisture or debris may be present around the axis.
