Product Description:

The SR-A0.0004.060-10.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is engineered to deliver closed-loop rotary motion to positioning tables, pick-and-place heads, and other precision axes found in automated assembly and test equipment. A resolver mounted on the shaft supplies feedback so the connected drive can regulate velocity and torque in real time. This arrangement supports coordinated motion where repeatable starts, stops, and position correction are required across multiple machine axes.

The motor reaches a rated speed of 6000 rpm, allowing high cycle counts in applications that demand rapid indexing. A torque constant of 0.62 Nm/A links phase current to developed torque, which helps match the motor to a compatible drive. During startup or a stalled condition, the rotor can withstand 0.4 Nm while drawing only 0.65 A, which helps limit heat buildup in compact systems. Position information is delivered at 8192 increments per revolution, and the resolver’s ±10 angular minutes of accuracy helps maintain low following error during interpolation. The feedback signal gives the controller fine positional updates during short indexing moves and continuous path control.

The motor has a reflected inertia of 9e-6 kg·m², including the feedback device, so the axis can accelerate quickly with modest drive effort. A square output flange measuring 55 mm follows the IM B5 mounting code, which simplifies attachment to machine plates or gearheads. The shaft uses a 9 mm diameter by 20 mm long spigot for keyed couplings, and the motor has a mass of 1.2 kg, which helps reduce moving load on gantries and small transfer units. An IP67 seal around the flange protects internal bearings from dust and coolant ingress. The 141 mm housing length keeps the package compact where installation space is limited.
