Product Description:

The SR-L1.0023.060-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is intended for industrial automation axes that require precise velocity and position control. The motor converts electrical energy from a drive into controlled mechanical rotation for packaging, assembly, and handling equipment, where repeatable motion is needed during frequent start-and-stop cycles. Its synchronous design supports coordinated motion on axes that must respond quickly to drive commands while maintaining stable positioning.

The unit reaches a rated speed of 6000 rpm, allowing fast cycle times in light-to-medium inertia loads. A torque constant of 0.73 Nm/A links drive current to produced torque, which helps the drive translate commanded current into predictable output. During startup, the motor can draw a locked-rotor current of 3.16 A, providing the initial torque needed to overcome static resistance before motion begins. An attached holding brake supplies 2.5 Nm of static torque so vertical or indexing axes remain fixed when power is removed. The brake is energized by 24 VDC and adds 0.30 kg to the assembly. The enclosure has an IP67 rating, and mechanical output is delivered through a Ø11 × 23 mm smooth shaft that supports compact machine layouts.

Dynamic behavior is influenced by a motor inertia of 1.3 × 10⁻⁴ kg·m², which is low enough for rapid acceleration while still supporting stable control with typical load couplings. The brake’s own inertia remains low enough to avoid a noticeable effect on servo loop response, and its 12 W coil rating helps limit heat rise during extended dwell periods. Position feedback is supplied by a resolver with a resolution of ±10 arcmin / 8192 increments per revolution, supporting smooth velocity estimation across the full speed range. This feedback arrangement allows the drive to track rotor position continuously during both low-speed and high-speed operation.
