8LSA46.D0030D200-0 by B & R Automation

B & R Automation manufactures the 8LSA46.D0030D200-0, a synchronous motor in the 8LS Synchronous Motors series. As a three-phase unit, it provides controllable torque and speed for automated conveyors, indexing tables, and robot joints. The motor serves as a direct rotary actuator, receiving current from a drive and returning encoder data so that the controller can hold position, synchronize multiple axes, and execute repeatable motion profiles across a manufacturing cell. This operating role makes it suitable for equipment that depends on accurate starts, stops, and coordinated movement over long production cycles.

The motor reaches a rated speed of 3000 rpm, allowing it to work with standard servo drives without additional gearing. A flange dimension of 100 mm provides the mounting interface and keeps alignment consistent across machines. Position feedback is provided by an Optical EnDat encoder with EnDat 2.2, so absolute position is available immediately after power-up. Power and feedback cables exit through an angled swivel connector housing that helps maintain clearance around nearby components. Internal heat is handled by self-cooling through free air circulation, eliminating the need for external fans. A standard holding brake secures the load whenever the drive is disabled, which is useful on axes that must remain stationary between moves.

Within the 8LSA configuration, the unit is supplied with a length 6 housing and does not include a reinforced bearing, which suits moderate radial loads while keeping the assembly lighter. The shaft end is a smooth shaft, allowing backlash-free clamping couplings, and the design omits an oil seal to reduce drag in self-ventilated service. Encoder memory holds 25 single-turn bits and zero multi-turn bits, delivering a single-turn absolute count suitable for indexing feeders and short-stroke gantries. This feedback arrangement fits applications that return to known positions repeatedly within one mechanical revolution and do not require stored multi-turn position data after shutdown.
