Product Description:

The SR-A3.0093.060-00.015 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the SR Synchronous Servo Motors series. Intended for industrial automation, it converts drive power into precisely regulated rotation for indexing tables, pick-and-place axes, and high-speed spindles. The unit follows the IM B5 mounting arrangement, uses a resolver for positional feedback, and carries two NTC temperature sensors that track winding heat. A 110 mm pilot diameter aligns the housing within a 116 mm flange, enabling straightforward coupling to gearboxes and machine frames.

Performance is centered on a rated velocity of 6000 rpm, allowing fast cycle times without exceeding the intended speed range. Electromagnetic output scales with a torque constant of 0.67 Nm/A, so each ampere of phase current produces approximately two-thirds of a newton-meter under steady-temperature conditions. During startup or jam conditions, the motor can develop a locked-rotor torque of 9.1 Nm while drawing a locked-rotor current of 13.5 A; these values help determine inverter requirements for stall protection. Dynamic response benefits from a rotor inertia of 0.0016 kg·m², which minimizes acceleration lag and simplifies the tuning of position loops in high-gain control systems.

Position fidelity is supported by a feedback resolution of 8192 increments per revolution, giving fine granularity for interpolation on digital drives. The flange has a frame size of 116 mm, which matches many IEC gear stages. The motor withstands shocks of up to 6 g, allowing installation on stamping or press lines where impulse loads are common. Bearings, seals, and winding insulation are rated for a minimum service life of 20,000 hours, supporting predictable maintenance intervals in continuous-duty equipment. The resolver supplies position information to the drive throughout operation, while the temperature sensors support thermal monitoring under changing loads.
