Product Description:

The 8SLSA43.R0022D100-0 synchronous servo motor is manufactured by B&R Automation for the 8LS Synchronous Motors series. Designed for closed-loop drives, it converts controlled AC power into precisely regulated shaft motion. Its 70 mm square flange permits direct installation in space-restricted assemblies. The motor provides torque and speed control for pick-and-place modules, indexing stations, and other automated machinery that requires accurate positioning.

At its continuous operating point, the motor delivers 806 W of mechanical power at 2200 rpm while drawing a nominal current of 1.6 A, producing a shaft torque of 3.5 Nm. The copper windings have a resistance of 11.53 Ω and an inductance of 81.1 mH. Current increases according to an electrical time constant of 7 ms, which indicates how quickly drive commands produce magnetic force. A torque constant of 2.22 Nm/A provides proportional torque for each ampere supplied by the inverter. The integrated resolver reports the rotor angle with an accuracy of 10 arcmin, providing the feedback required for precise position and velocity control. A stall current of 1.8 A works with a stationary torque of 4 Nm to hold loads at standstill. Length code 4 indicates the magnetic stack depth within the motor housing.

For short operating intervals, the winding can accept a peak current of 10.7 A, allowing the rotor to generate a maximum torque of 15.2 Nm during rapid acceleration or disturbance correction. The moving assembly has a reflected inertia of 1.87 kgcm², supporting fast speed changes without placing excessive demand on the drive. A back-EMF slope of 134.04 V/1000 rpm indicates the voltage generated as rotational speed increases. The servo drive must provide a corresponding increase in voltage to maintain controlled operation at higher speeds. Peak current and torque should be limited to short intervals to keep the windings within their allowable thermal range.
