Product Description:

The SR-A2.0013.060-14.000 servo motor is manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. The device is an electromechanical actuator for industrial automation, supplying closed-loop rotational motion to indexing tables, pick-and-place axes, and similar applications that require consistent speed and repeatable torque. An integrated holding brake allows static load retention when power is removed, while a resolver supplies rotor position feedback so a drive controller can maintain alignment during dynamic or standby conditions.

During operation, the rotor reaches a rated speed of 6000 rpm, providing ample headroom for high-cycle positioning programs. The motor has a torque constant of 0.76 Nm/A, so the controller produces 0.76 newton-meters for every ampere of phase current within the linear operating region. The holding brake resists back-driving with 3.2 Nm of static torque and is energized by a 24 V DC supply that draws 0.56 A. Engagement latency is limited to 19 ms, supporting emergency stops without appreciable overtravel. A resolver encoder with two sine-cosine channels sends feedback signals to the control electronics. Locked-rotor torque is rated at 1.3 Nm and requires a blocked-shaft current of 1.7 A. The brake has an inertia of 4 × 10⁻⁵ kg·m², which limits its effect on servo response.

The complete rotor and encoder assembly has an inertia of 2 × 10⁻⁴ kg·m², allowing the axis to accelerate quickly while remaining stable against oscillation when coupled to moderate mechanical loads. A smooth shaft with a diameter of 14 mm transmits torque, and the motor supports an admissible axial force of 70 N for light thrust loads without damaging the bearings. The housing is 206 mm long, and the motor has a total mass of 4.3 kg, reducing the moving weight in gantry-mounted applications. The holding brake releases after 29 ms, restoring free shaft rotation before the next commanded motion sequence begins.
