Product Description:

The SF-A2.0013.030-04.050 servo motor is produced by Bosch Rexroth Indramat within the SF Servo Motors series. It serves as a compact rotary drive for positioning tasks in industrial automation, converting controlled current into mechanical torque that can be regulated through its integrated encoder and holding brake. Designed to work with Rexroth digital drive controllers, the unit supports repeatable motion in conveyors, pick-and-place heads, light-duty tool spindles, and other axes that require accurate speed control, reliable holding at standstill, and short indexing moves.

Mechanically, the unit uses a square housing with a 100 mm flange and a center hole machined to DIN 332-DS M5 for alignment. Power is transmitted through a shaft ground to a tolerance of Ø14 k5, and the shaft extends 30 ±0.5 mm with an A5×5×25 feather key for hub engagement. During nominal operation, the rotor reaches 3000 rpm, and each ampere produces 1.5 Nm/A of torque because of the laminated magnetic circuit. Position feedback is generated at 8 million increments per revolution, giving the drive fine motion resolution for closed-loop control. Locked-rotor current is limited to 0.9 A while static torque is 1.3 Nm, which helps control winding heat during holding conditions.

The electromechanical brake supplies 3.2 Nm of holding torque and is energized by 24 V DC ±10% at 0.56 A, securing vertical or suspended loads when drive power is removed. Dynamic behavior is supported by a rotor inertia of 2 × 10⁻⁴ kg·m², which balances acceleration response with stable rotation. The overall assembly mass is 4.3 kg, helping the motor suit lightweight gantries and indexing tables without adding unnecessary moving load. With an active length of 206 mm, it fits compact machine spaces while still supporting cyclic duty within the stated operating limits.
