8LSA75.EB022C104-0 by B & R Automation

The 8LSA75.EB022C104-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. It is identified in the series by the internal designation 8LSA and incorporates a reinforced A-side bearing for added radial load support. Using a standard mounting flange and a shaft end with a key, the unit is intended for positioning or velocity-controlled axes in automated machinery where compact, maintenance-friendly rotary drives are required. A holding brake and an oil seal are not included, so external load-holding or environmental sealing measures must be provided when needed.

The motor's nominal mechanical output is governed by a rated speed of 2200 rpm, allowing direct coupling to gearboxes or loads that match this operating window. Rotor position and velocity feedback are handled by an Inductive EnDat sensor, which combines good shock resistance with absolute position data. This transducer supplies a 19/12-bit resolution for single-turn and multi-turn tracking, enabling precise interpolation by the drive controller. A built-in counting register stores up to 4096 revolutions without external power, eliminating homing routines after shutdowns. Mechanically, the housing conforms to a 190 mm flange, simplifying interchangeability with other IEC-sized motors in the same machine frame.

Thermal management relies on a self-cooling principle that uses free air circulation around the stator, so machine layouts must provide unobstructed airflow to maintain winding temperatures. Power and feedback lines exit through a straight top connector; this direction eases cable routing in cabinets where lateral clearance is limited. The reinforced A-side bearing works with the motor's mounting flange to absorb higher belt or pinion loads than standard 8LS variants. Physical dimensions use length code 5, which corresponds to the stator stack depth needed for the required torque while keeping overall mass compatible with common pick-and-place mounting equipment. The EnDat 2.1 interface is used for feedback communication with a compatible drive.
