Product Description:
The SR-L0.0009.060-04.000 is a synchronous servo motor produced by Bosch Rexroth Indramat within the SR Synchronous Servo Motors series. It is intended for tightly controlled positioning and velocity regulation in industrial automation, where a drive module supplies current to generate proportional torque on the keyed output shaft for conveyors, small rotary actuators, or pick-and-place axes. The motor converts electrical drive commands into smooth rotary motion, allowing the control system to correct speed and position errors during operation.
The motor can reach a rated speed of 6000 rpm. At this operating point, the drive must supply a standstill torque reserve of 0.9 Nm and a standstill current of 1.31 A. Its electromagnetic design yields a torque constant of 0.73 Nm/A, so each ampere of phase current produces nearly three-quarters of a newton-meter. The total rotational inertia, including the resolver encoder, is 0.33 × 10⁻⁴ kg·m², which supports quick acceleration without excessive drive demand. Mechanically, the shaft measures 9 × 20 mm and uses a key to help prevent slippage under cyclic load. A 40 j6 flange pilot centers the housing, while the overall length with the integrated brake is 221 mm, which helps the motor fit compact machine layouts. The holding brake is energized by 24 V DC within a tolerance of ±10% and absorbs 8 W during engagement. A resolver provides analog rotor position feedback to the drive for closed-loop motion control.
During static clamping or emergency stops, the brake supplies 1.2 Nm of holding torque, and the design permits up to 13 N of axial force on the shaft without damage. Motion feedback detail is high because the resolver is interpolated to an effective resolution of 8192 incr/rev, while its mechanical accuracy stays within 10 arcmin. This combination supports repeatable axis behavior in light material-handling tasks that need stable positioning without external load sensors.
