Product Description:

The SF-A2.0041.060-00.050 is a servo motor produced by Bosch Rexroth Indramat within the SF Servo Motors series. As an electromechanical actuator, it converts electrical energy from a drive into controlled rotary motion for positioning axes in automated machinery. The motor’s compact build allows direct coupling to gearboxes or load shafts where high speed and moderate holding torque are required in packaging, pick-and-place, or printing stations. Closed-loop servo control allows the motor to respond quickly to speed changes and position commands during repetitive machine cycles.

Mechanical dimensions show how the unit fits against machinery faces. A square mounting interface of 100 mm allows the housing to bolt to standardized servo frames, and the overall body length without a brake is 233 mm, so space inside cabinets or machine arms can be calculated precisely. Performance at the drive shaft is characterized by a rated speed of 6000 rpm, enabling rapid traverse cycles when commanded by the controller. At zero speed, the winding produces 4.0 Nm of standstill torque, which is the maximum continuous holding level before thermal limits are reached. With a torque constant of 0.73 Nm/A, each ampere of stator current contributes a predictable amount of electromagnetic torque for straightforward current-loop tuning.

A chassis weight of 7.1 kg minimizes moving mass on linear axes while still providing enough structural stiffness. Rotor inertia is held to 6 x 10^-4 kg·m², allowing fast acceleration without overstressing the drive. This balance helps the axis change speed quickly without placing unnecessary demand on the drive or coupling. To reach the quoted holding torque, the drive must supply a standstill current of 5.6 A, so thermal modeling should allow sufficient margin. Operation is specified up to ≤1000 m installation altitude, ensuring cooling and dielectric clearances remain effective at standard plant elevations. The precision-ground shaft measures 14 mm by 30 mm for coupling to keyed hubs or clamping collars.
