Product Description:

B&R Automation’s 8LSA37.DB030S200-3 belongs to the 8LS Synchronous Motors series and is supplied as a three-phase synchronous unit for motion axes that need tight speed regulation in automated assembly, packaging, and material-handling lines. The motor carries the internal designation 8LSA and follows a standard build without a reinforced bearing, making it a general-purpose choice where low radial loading is expected. Its purpose is to convert electrical power into controlled rotary motion that can be servo-regulated through the EnDat feedback channel in multi-axis systems.

The drive reaches a rated speed of 3000 rpm, matching typical servo inverter outputs for conveyor and pick-and-place duties. The motor has a flange dimension of 91.3 mm, so the housing fits compact mechanical frames. Position feedback is delivered by an inductive EnDat encoder that uses differential signaling to resist electrical noise. Its data depth is 19/12 bits for single-turn and multi-turn increments, which supports fine interpolation while retaining absolute position. This encoder operates on EnDat protocol release 2.2, allowing digital temperature monitoring and automatic parameter transfer. The motor uses a smooth shaft end to simplify coupling, and its length code 7 corresponds to a rotor stack sized for the torque class. A single hybrid connector routes both power and transducer lines so wiring is consolidated at the cabinet interface. Multi-turn tracking extends to 4096 mechanical revolutions, so absolute position can be retained across extended power-off intervals.

A standard holding brake helps maintain load position during shutdowns. The hybrid interface uses a single-cable solution to reduce harness count on moving axes. Thermal management relies on self-cooling with free air circulation, eliminating the need for external fans or liquid jackets. The unit is at product revision 3. The motor does not have an oil seal, so the shaft should not be exposed to pressurized lubricants.
