Product Description:
The 8LSA66.EB045D000-1 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. Delivered in the 8LSA standard configuration without reinforced bearings, the unit is intended for direct flange mounting on machinery that requires precise rotary motion in industrial automation. The absence of an internal holding brake and an oil seal simplifies the mechanical layout when external clamping devices are used and the surrounding environment is clean.
The motor relies on a self-cooling design that exchanges heat with free airflow, so no external fan or liquid cooling circuit is required. A rated speed of 4500 rpm provides the maximum continuous rotor velocity under nominal load, while the 190 mm square flange provides the interface for coupling the motor to gearboxes or machine frames. Position feedback is supplied by an inductive EnDat sensor, a noncontact system that reduces wear compared with optical encoders. The sensor delivers single-turn and multi-turn position data with a resolution of 19/12 bits, providing fine angular granularity for tight speed control and repeatable indexing. This feedback arrangement allows the connected drive to obtain accurate rotor position information during controlled motion. Its noncontact operation also avoids the contamination sensitivity commonly associated with optical sensing components.
The encoder uses EnDat version 2.1, which supports serial communication of diagnostic and electronic nameplate data to the drive. Multi-turn tracking covers 4096 revolutions, so absolute position is retained after power loss without requiring a battery. Power and feedback cables are routed through an angled swivel feed-through that reduces cable strain in compact installations, and a mating connector completes the detachable wiring arrangement. Length code 6 indicates the longest stator stack available for this frame size, increasing torque capacity without changing the flange dimensions. The smooth shaft end avoids the stress concentration associated with a keyway. Flange mounting also eliminates the need to align foot brackets during installation, allowing the motor housing to attach directly to a compatible machine surface or gearbox interface.
