Product Description:

Bosch Rexroth Indramat supplies the SR-L1.0012.060-04.000 as part of the SR Synchronous Servo Motors series for closed-loop positioning and velocity control in compact automation axes. The motor converts drive current into rotary motion through a permanent-magnet rotor and sends angular position data to the drive, allowing precise command execution in pick-and-place modules, indexing tables, and lightweight gantries. Under continuous load, the motor reaches a rated speed of 6000 rpm, making it suitable for high-cycle machinery where short movement times are important.

Steady-state torque production corresponds to a torque constant of 0.64 Nm/A, so a drive current of 3 A produces approximately 1.9 Nm. Static load retention is supported by a holding torque of 2.0 Nm, which keeps the shaft stationary when motion commands cease. Dynamic performance is influenced by a rotor inertia of 0.63 × 10⁻⁴ kg·m²; this low inertia allows the servo to accelerate rapidly while remaining controllable. With its integrated brake, the assembly weighs 2.11 kg, simplifying installation on small vertical axes or mobile platforms. The locked-rotor current is 1.9 A, and the corresponding stall torque is 1.2 Nm, which the drive must accommodate during brief startup or alignment events. The shaft projects 23 mm beyond the flange, allowing couplings to seat fully without spacers.

Position holding during a power loss is provided by an electromechanical brake that operates at 24 V and draws 0.4 A. The integrated brake increases the motor’s overall length to 220 mm while keeping the assembly compact enough for distributed motion systems. Feedback is supplied by a resolver with an electronic resolution of 8192 increments per revolution, supporting precise position and velocity control without an external encoder. Mechanical output is transmitted through a keyed shaft measuring 11 mm in diameter, providing a positive connection for small timing pulleys, clamping hubs, and compatible planetary gearheads.
