Product Description:

The SR-L0.0004.060-04.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It functions as a compact rotary drive element for CNC axes, pick-and-place modules, and general automation, converting the regulated output of a servo amplifier into mechanical motion with precise velocity and position control. Its compact format suits installations where accurate positioning and fast response are required in limited space. Because it is a synchronous design, the motor can maintain precise rotor alignment with the command signals from the connected drive.

At its rated speed of 6000 rpm, the motor delivers continuous motion that scales linearly with input current thanks to a torque constant of 0.62 Nm/A. The square mounting interface measures 55 mm, which matches IEC 55 gearheads and keeps the frame small for tight machine layouts. Position feedback comes from a resolver with a resolution of 8192 incr./rev. and a precision of ±10 angular minutes, enabling fine interpolation inside the drive. The holding brake supplies 1.0 Nm of static torque to hold the shaft during idle phases. Mechanical output is transferred through a Ø9 × 20 mm shaft with a keyway and feather key for reliable torque transmission.

During start-up, the rotor can withstand a locked-rotor torque of 0.4 Nm while the drive limits current to protect the windings. The brake coil operates on 24 VDC and engages in less than 30 ms after motion stops. Low mechanical inertia of 0.09 × 10^-4 kgm² supports rapid acceleration and helps reduce overshoot in short travel strokes. Internal bearings are grease packed for a minimum service interval of 20,000 hours, which fits planned maintenance intervals in packaging and electronics assembly equipment. The motor is well suited to compact axes that require frequent starts, quick settling, and reliable holding at standstill.
