Product Description:

The SR-A1.0008.060-00.000 from Bosch Rexroth Indramat belongs to the SR Synchronous Servo Motors series. It functions as the rotary element in closed-loop motion axes, translating commanded current into controlled shaft rotation for positioning and velocity control in automated equipment. The resolver encoder supplies continuous position feedback for precise closed-loop regulation.

The motor can reach a rated speed of 6000 min⁻¹, allowing rapid indexing in compact machinery where cycle time is critical. A torque constant of 0.60 Nm/A links phase current to developed torque, simplifying current-loop tuning in the drive. During start-up, the rotor can deliver a locked-rotor torque of 0.8 Nm while drawing a locked-rotor current of 1.35 A, data used when sizing fuses and selecting acceleration profiles. The windings are energized from a DC link of 670 V, matching high-voltage inverter families. Mechanical integration is aided by a flange diameter of 70 mm, and this B5 face mount maintains alignment on gearboxes or adapter plates. An inertia value of 0.43 × 10⁻⁴ kg·m², measured with the resolver installed, supports high dynamic response without excessive drive gain.

The unit weighs only 1.4 kg, reducing reflected mass on moving carriages and easing manual installation. When a mating connector is attached, the housing meets a protection rating of IP67, so dust and coolant are kept out in washdown or machining cells. The shaft is machined to Ø11 × 23 mm and furnished with a keyway and feather key, providing positive torque transfer into couplings or pulleys. Construction type IM B5 specifies a face-mount orientation, while the 156 mm overall length keeps the motor compact in tight electrical cabinets. Because the supply kit omits a mating connector, cabling can be selected to match application-specific routing and strain-relief schemes.
