Product Description:
The 8LSA44.DA045S200-3 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. This unit serves as a compact drive element in industrial automation applications that require precise torque and speed control, including positioning tables, pick-and-place heads, and packaging lines. A standard 8LSA configuration without reinforced bearings keeps the weight low, while the mounting flange allows direct attachment to machine frames and gearboxes. The motor works with a compatible servo drive to provide controlled rotary motion during repetitive production cycles.
The motor reaches a rated speed of 4500 rpm, supporting fast cycle times when paired with a suitable servo drive. A flange diameter of 100 mm establishes its mechanical envelope and supports direct integration with compatible mounting surfaces. Position feedback comes from an inductive encoder that supports EnDat 2.2 communication, enabling digital transmission of absolute position data to the controller. The encoder resolution is 19/0 bits, providing 19-bit single-turn position data without multi-turn counting. This arrangement gives the controller detailed position information throughout one complete shaft revolution. Power, signal, and feedback conductors use a single-cable solution, reducing cabinet terminations and simplifying cable routing compared with separate motor and encoder leads.
Axis holding is handled by a standard holding brake that clamps the rotor when power is removed, preventing drift on vertical loads. Heat is removed through self-cooling with free air circulation, eliminating the need for external fans or liquid cooling circuits. A smooth shaft supports connection to backlash-free clamping hubs, while the absence of an oil seal minimizes running friction in clean, dry environments. The motor is product revision 3. Its stator stack uses length code 4, and a hybrid connector provides a consolidated interface for field wiring. The single-turn absolute feedback allows the controller to determine the angular shaft position after startup without relying on multi-turn tracking components.
