Product Description:
The SR-A0.0008.060-00.008 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. As a compact rotary actuator for industrial automation, it converts drive current into precisely regulated torque and speed. The motor is suitable for pick-and-place heads, small conveyors, and indexing stations that require accurate movement within a limited installation area.
This model delivers a rated speed of 6000 rpm, allowing fast motion cycles without external gearing. A torque constant of 0.67 Nm/A links drive current to shaft torque, giving the controller a predictable mechanical output for each ampere supplied to the windings. The square mounting interface has a flange diameter of 55 mm, while the centering collar and four bolts match the IM B5 mounting style for straightforward face mounting. Power is transmitted through a keyed shaft measuring 9 mm in diameter and 20 mm in length, making it suitable for small couplings or pulleys. With the rotor blocked, the motor can produce 0.8 Nm of torque, providing the maximum static torque available at zero speed. The motor has an overall length of 156 mm, and its cable-routing options support installation in tight machine frames.
Position feedback is provided by a resolver with a resolution of 8192 increments per revolution, allowing the drive to maintain fine angular control during positioning and speed regulation. When the rotor is blocked, the phase windings draw a current of 1.2 A, which can be used when selecting suitable fuses and thermal protection. The housing and stator have a combined mass of 1.3 kg, minimizing the mechanical load placed on linear axes and robotic joints. Dynamic response is aided by a rotor inertia of 0.15 × 10⁻⁴ kg·m², which supports rapid acceleration without excessive control effort. The low rotating inertia also helps the motor respond quickly when the drive commands frequent changes in speed or direction. Its compact mass and short housing allow mounting brackets to remain relatively small while maintaining the rigidity needed for accurate axis movement.
