8LSA35.R2060D000-3 by B & R Automation

B & R Automation's 8LSA35.R2060D000-3 is a three-phase synchronous motor in the 8LS Synchronous Motors series. It is intended for positioning and speed-control duties in industrial automation systems that use servo drives for coordinated motion. Its synchronous design supports accurate speed regulation when paired with a compatible drive controller. The motor uses a flange mount for machine attachment, and its smooth shaft transfers torque directly to couplings or gear stages. The unit is identified as designation 8LSA and is supplied in product revision 3.

The motor has a rated speed of 6000 rpm and a nominal current of 2.2 A. At that operating point, it produces 1005 W of nominal output power and 1.6 Nm of continuous torque. During short load surges, current can rise to 13.6 A, while stall values are limited to 3.2 A and 2.3 Nm. A stator resistance of 3.02 ? works with a torque constant of 0.73 Nm/A and a voltage constant of 43.98 V/1000 rpm to determine inverter demand. Resolver feedback provides 6 arcmin precision, and power and feedback connections use an angled swivel connector with matching connector hardware. This feedback allows the drive to monitor rotor position during closed-loop operation.

The motor can supply up to 9.2 Nm of peak torque for rapid indexing moves, and the rotor inertia is 0.9 kgcm². Its mass is 4.4 kg, and the unit uses length code 5 with a 91.3 mm flange for compatibility with earlier 8LSA layouts. Cooling is handled by self-cooling with free-air circulation, and the winding inductance is 15.6 mH, which influences current rise during dynamic operation. The configuration is standard, with no reinforced bearing, oil seal, or holding brake fitted. The absence of a holding brake means load retention must be provided elsewhere when the motor is not energized.
