Product Description:

The 8LSA34.R0060D300-0 is a compact servo motor produced by B&R Automation within the 8LS Synchronous Motors series. Designed for flange mounting, the unit converts controlled three-phase electrical energy into mechanical output for positioning axes, conveyors, and robotic joints that require accurate speed and torque regulation. A standard holding brake secures the shaft when power is removed, while the angled swivel connector simplifies cable routing in confined machine spaces.

The motor has a rated speed of 6000 rpm, making it suitable for applications that require rapid indexing without gear reduction. At its nominal operating point, it delivers 628 W of mechanical power and a continuous torque of 1 Nm while drawing 1.37 A from the drive amplifier. The electromagnetic design has a torque constant of 0.73 Nm/A, providing a proportional relationship between phase current and motor torque. Four pole pairs on the rotor work with resolver feedback to maintain synchronization between the electrical angle and actual rotor position. The self-cooling design relies on free air circulation, eliminating the need for external blowers or liquid cooling during nominal operation.

For transient loads, the motor can produce a peak torque of 6 Nm, while its stall torque of 1.5 Nm supports demanding low-speed and stationary operating conditions. The drive electronics may momentarily supply up to 8.9 A to generate peak torque, so the cable conductors and swivel connector must accommodate the associated current and thermal load. Positional accuracy is maintained within 10 arcmin through the resolver feedback system. A keyed shaft end prevents coupling slippage when torque is transferred to the connected mechanism. The 91.3 mm flange centers the motor accurately against the machine frame and supports consistent alignment with the driven equipment.
