8LSA75.DA030S100-3 by B & R Automation

The 8LSA75.DA030S100-3 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. It serves as a torque source in industrial automation, driving axes that require consistent velocity and accurate positional feedback under servo control. By integrating the power and feedback connections used in this series, the motor simplifies cabinet wiring and supports high-performance motion control tasks in packaging, handling, and assembly lines.

The motor reaches a rated speed of 3000 rpm, allowing direct coupling to gearless mechanisms where high shaft velocity is required. Position measurement is handled by an Inductive EnDat encoder that operates in single-turn mode and transmits absolute data with a resolution of 19 single-turn bits and zero multi-turn bits, which suits applications that reestablish position after each power cycle. This feedback channel works with EnDat version 2.2, so modern servo drives can use automatic parameter detection and cable monitoring. A flange dimension of 190 mm establishes the mounting envelope and aligns the shaft center with adjacent machinery. Heat is removed through self-cooling through free circulation, so no external blower or liquid circuit is required. The housing uses length code 5 to balance torque and inertia within the 8LS range.

Electrical power and encoder signals share one cable through a single-cable solution interface that terminates in a sealed connector, reducing cable count between the motor and drive. Mechanical integration is simplified by the mounting flange, which mates with the series bolt circle, and by a shaft end supplied with a key for secure torque transmission to pulleys or couplings. The motor uses a standard configuration without a reinforced bearing, indicating normal radial load capability. It has no holding brake or oil seal, and it is released as product revision 3.
