Product Description:

The SR-L1.0016.060-00.000 synchronous servo motor is produced by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. As a compact rotary actuator, it converts controlled three-phase electrical power into repeatable mechanical torque for positioning axes, pick-and-place heads, and auxiliary drives on automated machinery. Its design supports high-speed yet precise servo loops, allowing the drive system to maintain tight motion profiles without external gear reduction. This makes it suitable for packaging, indexing, and transfer motions that depend on repeatable starts, stops, and short settling times. The compact housing and sealed construction make it suitable for direct installation inside production cells where space is limited and routine splash exposure can occur.

The stator and housing fit a 70 mm flange. The motor measures 190 mm in length and has a mass of 4.065 kg, which helps it fit light machine frames without adding much load to the axis. Mechanical attachment follows the IM B5 pattern, while an Ø11 × 23 mm shaft transfers power to couplings or pulleys. This layout supports direct face mounting to machine plates or gearheads and keeps the drive train compact. During operation, the winding delivers a continuous standstill torque of 1.6 Nm, and a blocked rotor draws 2.2 A to hold load without motion. Dynamic tasks benefit from a rated speed of 6000 rpm, and protection to IP67 helps the motor resist dust and water ingress without additional covers.

A resolver provides feedback with a base resolution of 8192 incr./rev., and internal interpolation supports smooth command tracking across the speed range. The feedback signal gives the controller reliable rotor position information for speed regulation and phase alignment. Electrical angle error remains within ±10 angular min, which helps preserve accurate commutation at high velocity and during rapid direction changes. The electromagnetic design produces a torque constant of 0.73 Nm/A, so required current can be related directly to demanded load torque in the matching drive. With a rotor inertia of 1.1 × 10⁻4 kg·m², the motor can accelerate quickly while still maintaining stable closed-loop control.
