Product Description:
B & R Automation manufactures the 8LSA44.R2030D200-3 as part of the 8LS Synchronous Motors series. The unit is a servo motor used to drive machine axes directly, providing closed-loop speed and position control for pick-and-place modules, indexing tables, and packaging lines. It combines mechanical, electrical, and feedback components in one housing, simplifying system integration while giving the controller a fast dynamic response. The motor has the A-designation standard configuration and uses standard bearings rather than reinforced bearings, supporting compact installations and repeatable operation.
At a rated speed of 3000 rpm, the rotor supports continuous operation while matching common servo drive requirements. The mounting interface uses a 100 mm square flange pattern that aligns with compatible gearboxes and machine frames. The maximum positional deviation is 6 arcmin, making the motor suitable for medium-precision indexing tasks. Rotor angle feedback is produced by a resolver, whose analog sine-cosine signals remain stable under vibration and electrical noise. Power and signal conductors exit through an angled swivel connector system, reducing cable strain where installation space is limited. A bayonet-style connector housing provides a secure electrical connection during machine operation. The motor is product revision 3, and its length code 4 indicates the selected stack depth for this configuration.
Thermal control relies on self-cooling through free air circulation, so the housing requires unobstructed ambient airflow for heat dissipation. An integrated standard holding brake secures the load when the drive is disabled, helping prevent movement on vertical or suspended axes. Output torque is transmitted through a smooth shaft, which supports clamping or press-fit couplings without requiring a keyway. As a three-phase synchronous motor, the unit draws balanced current from the inverter and produces controlled torque throughout the electrical cycle. The shaft does not include an oil seal, which reduces running friction in applications where additional sealing is unnecessary. Its direct-drive capability allows the motor to be connected to suitable machine mechanisms without an intermediate transmission when the required torque and speed are within the operating range.
