Product Description:

The 8LSA75.E0022D100-0 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. Supplied under the internal designation 8LSA, the unit serves as a rotary actuator in industrial automation, receiving regulated current from a servo drive and producing torque for indexing tables, conveyors, and Cartesian axes. This type of motor supports controlled speed and position response in closed-loop systems. Its standard configuration omits reinforced bearings, which keeps the motor suited to general-purpose motion tasks where compact dimensions are preferred.

Thermal management is handled by self-cooling with free circulation, eliminating external fans and simplifying installation. Because cooling is passive, the housing removes heat without separate blower hardware at the machine. Under nominal conditions, the rotor reaches 2200 rpm, permitting direct coupling to medium-speed machinery without gear reduction. Position data comes from an optical EnDat feedback system that communicates through the EnDat 2.1 protocol for high-resolution absolute position reporting. This arrangement allows the servo drive to monitor rotor position accurately during startup and operation. A 190 mm square flange provides the primary mounting face and matches IEC dimensions. An angled swivel connector routes power and encoder lines away from the shaft axis, and the molded plug connector can be locked with standard field-installable mates.

Length code 5 indicates the active core depth and identifies the longer magnetic stack used in this version. The motor has no mechanical brake, so holding at standstill must be provided by drive torque or an external clamp. The output shaft is machined with a key, providing a positive drive interface for couplings and pulleys. The keyed shaft helps prevent slip in mechanical connections that rely on positive engagement. Position information uses a 13/0 bit structure, which corresponds to single-turn operation. No oil seal is installed, so the surrounding machine must provide its own barrier when fluids or contaminants are present.
