Product Description:
The 8LSA46.DB030S100-3 is a three-phase synchronous motor manufactured by B & R Automation within the 8LS Synchronous Motors series. Designed for industrial automation, the unit connects directly to servo drives to deliver accurate torque and speed control for packaging lines, material-handling stages, and general-purpose motion axes. The “8LSA” designation indicates a standard configuration without reinforced bearings, making the motor suitable for machines that impose moderate radial loads.
At a rated shaft speed of 3000 rpm, the motor provides continuous rotary motion within the output range of compatible B & R servo inverters. Position feedback is provided by an inductive EnDat encoder that uses protocol version 2.2, enabling bidirectional communication of position, temperature, and diagnostic data over a single data pair. The encoder provides 19 single-turn bits and 12 multi-turn bits of resolution, allowing the drive to resolve one revolution into 524,288 positions while tracking as many as 4,096 mechanical revolutions. Thermal regulation relies on self-cooling with free air circulation, eliminating the need for an external blower when sufficient ambient airflow is available around the motor housing.
Power, signal, and encoder conductors are combined in a single-cable hybrid solution that terminates at a connector, reducing the number of cable runs and cabinet penetrations. A square mounting face with a 100 mm flange dimension supports alignment with compatible IEC adapters. The motor has a keyed shaft that transfers torque through standard couplings and provides positive mechanical engagement under changing loads. Absolute multi-turn tracking allows the control system to recover the recorded shaft position after a power interruption without requiring a homing cycle. The motor also has a mounting flange, no oil seal, and no holding brake, so an external method is required when a stationary load must remain secured after motor power is removed. Its length code is 6 for the magnetic stack, and the product revision is 3.
