Product Description:

The SR-A2.0041.060-00.000 belongs to the SR Synchronous Servo Motors series from Bosch Rexroth Indramat. It converts electrical energy into tightly regulated mechanical rotation and serves as the actuation element for multi-axis platforms used in packaging, assembly, and material-handling lines where precise positioning and repeatable speed profiles are mandatory.

It operates from a DC link of 670 V, allowing high power density while keeping cabling current moderate. This elevated bus level supports smaller conductor sizes and shortens current rise time in the stator. At its rated speed of 6000 min⁻¹, the motor sustains rapid cycle throughput for indexing tables. A torque constant of 0.73 Nm/A ties phase current to output torque, so the locked-rotor current of 5.6 A will produce the locked-rotor torque of 4.0 Nm required for break-away or emergency stops. Resolver feedback is used, and the resolver supplies 8192 increments per revolution, giving the controller fine position granularity. The high bus voltage also improves energy recovery during deceleration, reducing overall system losses. This relationship between voltage, current, and torque lets a compact drive amplifier be chosen without oversizing its thermal section.

Mechanical details support straightforward installation. The B5 mounting flange measures 100 mm, aligning the stator bore concentric to the load interface. The rotor’s moment of inertia is 6 × 10⁻⁴ kg·m², which balances quick acceleration with stable coupling, while the motor mass of 7.1 kg eases handling on lightweight axes. Housing protection is rated at IP67 (except the output side), keeping internal parts sealed during wash-down or dust exposure. Additional features include a 233 mm overall length, IM B5 footless mounting, and a Ø14 × 30 mm shaft with keyway and feather key for positive torque transmission.
