Product Description:

The SF-A2.0041.060-10.050 is a servo motor produced by Bosch Rexroth Indramat as part of the SF Servo Motors series. In factory automation, this motor supplies closed-loop rotary motion for positioning axes that need high feedback resolution and stable thermal behavior under natural convection cooling. An absolute encoder with ±20 arcsec accuracy sends position data directly to the drive, allowing the controller to synchronize machine cycles without external transducers during continuous operation.

This model reaches a rated speed of 6000 rpm, enabling fast indexing in pick-and-place, printing, or packaging lines. To create torque, the windings are energized from a DC link that sits at 670 V, so compatible drive modules can connect without step-up converters. Each ampere supplied to the stator produces mechanical output in proportion to a torque constant of 0.73 Nm/A, which supports current-based control loops. Rotor position is tracked by an optical measuring system that delivers 8 million increments per revolution, providing sub-arcminute granularity for contouring applications. If the shaft is blocked during a jam or stall condition, the motor can withstand a locked-rotor torque of 4.0 Nm without exceeding thermal limits monitored by its dual NTC temperature sensors.

A moment of inertia of 6 × 10⁻⁴ kg·m² balances dynamic response with load stability and helps limit overshoot during rapid reversals. During stall tests, the phase windings draw a locked-rotor current of 5.6 A, a value used to size fuses and set drive overcurrent protection. Installation weight is controlled, as the unit registers 7.1 kg without a holding brake, and the rectangular DIN 100 mounting interface uses a flange size of 100 mm that aligns directly to gearboxes or mechanical frames. Its 233 mm overall length supports compact installation, and the motor is supplied without a mating connector so cable termination can be matched to the application.
