8LSA44.DA045S200-3
The 8LSA44.DA045S200-3 is a motor produced by B&R Automation within the 8LS Synchronous Motors series. It uses the 8LSA type code and carries product revision 3. As an automation component, the motor converts electrical power into rotary motion for positioning axes or continuous-duty drives on machine tools and packaging lines. A standard bearing arrangement is used instead of a reinforced bearing, which helps keep the weight moderate, and the mounting flange allows direct installation on rigid machine frames. This layout suits applications that need accurate motion with a compact mechanical footprint.
The motor has a rated speed of 4500 rpm, permitting relatively high surface velocities on coupled loads. A flange dimension of 100 mm sets the footprint for bolt patterns and shaft height. Feedback is supplied through an Inductive EnDat encoder that operates with EnDat version 2.2 and sends digital position data over the same hybrid cable used for power. This arrangement uses a single-cable hybrid connection, and thermal regulation relies on self-cooling with free air circulation rather than an external blower. Because cooling depends on the surrounding air, the motor can operate without separate fan wiring or added air-duct hardware. The connector-style cable exit supports straightforward routing, and the smooth shaft end reduces fretting on slip-fit couplings.
Fine control is aided by a 19/0 bit resolution, which provides absolute position data without multi-turn counting and matches the motor's single-turn capability. Holding position during shutdown is handled by a standard holding brake, which helps keep the axis in place after power is removed. The motor uses a three-phase synchronous operating principle for constant torque per ampere, while length code 4 balances inertia against continuous torque. An oil seal is not present, so this shaft arrangement is better suited to clean, dry environments than to areas with fluid exposure. The flange, connector housing, and smooth shaft support compact integration where cable space around the machine is limited.
