Product Description:

The SR-A1.0023.060-10.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is intended for closed-loop industrial axes where rapid speed changes and accurate torque control are required, such as pick-and-place modules or compact machining spindles. By combining a resolver for real-time position feedback with integrated temperature monitoring, the unit acts as the primary electromechanical element that converts drive current into controlled rotary motion.

Mechanically, the motor attaches through a 70 mm centering flange that matches the IM B5 mounting pattern, while a smooth Ø11 × 23 mm shaft transmits power without keys to minimize backlash. The rated operating point reaches 6000 min⁻¹; at this speed the windings deliver torque in proportion to their constant of 0.69 Nm/A. During start-up or when a load jams, the rotor can hold a stall torque of 2.3 Nm, and the corresponding locked-rotor current peaks at 3.3 A. These transient values inform inverter current limits and mechanical coupling design. A mass of 2.6 kg and a housing length of 236 mm keep the moment load on mounting plates low, while the smooth-shaft style eases pulley or collet integration.

Additional characteristics support long service life and system safety. The enclosure carries a protection rating of IP67, allowing temporary immersion and complete dust exclusion in washdown zones. Total rotor inertia, including the resolver, is 1.20 × 10⁻⁴ kg·m², promoting fast acceleration without overshoot when paired with low-inertia loads. Two integrated temperature sensors, specified as 2 NTCs, supply thermal data for drive shutdown before winding limits are exceeded. Bearing assemblies are rated for a minimum of 20000 h under standard loading conditions, giving a predictable maintenance interval for high-cycle production equipment.
