Product Description:

The SR-L0.0002.060-14.000 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied in the SR Synchronous Servo Motors series. It is intended to deliver precise rotary motion for automated pick-and-place modules, compact positioning tables, and other axes where accurate speed and torque control are required. The integrated resolver provides continuous position feedback, and the built-in brake secures the shaft when drive power is de-energized, making the unit suitable for vertically oriented loads. This arrangement also supports applications that require repeatable starts, stops, and holding at standstill within a compact motor package.

Mechanical dimensions keep the motor small yet capable. A square flange of 55 mm forms the primary mounting interface. The shaft is 9 mm in diameter and 20 mm long, so it can connect directly to couplings or pulleys. Overall length is 160 mm, and the assembly mass is 1.18 kg, while the rotor itself has an inertia of 0.06 × 10⁻⁴ kg·m² to help keep moving mass low. Dynamic characteristics include a torque constant of 0.44 Nm/A, which allows proportional torque generation from the drive amplifier. During startup, the motor can develop 0.2 Nm of locked-rotor torque at a locked-rotor current of 0.45 A. Once released, it reaches a rated speed of 6000 rpm, providing a wide velocity range for rapid indexing and dwell cycles.

The parking brake is sized for static load retention and supplies 1.0 Nm of holding torque. It adds only 0.068 ×10⁻⁴ kg·m² to the total inertia, which helps limit its effect on acceleration. The brake coil draws 0.5 A from a stabilized supply of 24 VDC, allowing direct connection to common control cabinet power buses. For feedback, the resolver supplies shaft angle information with a resolution of 8192 increments per revolution, so the drive can close high-bandwidth loops without an additional encoder. That feedback supports smooth low-speed regulation and accurate positioning during repeated short-stroke motion.
