8LSA34.E1030D100-0
The 8LSA34.E1030D100-0 is a three-phase synchronous servo motor manufactured by B&R Automation within the 8LS Synchronous Motors series. It is identified in the series by the 8LSA designation, which indicates a standard design without reinforced bearings, and it is intended to deliver position-controlled rotary power to automated machinery axes. A mounting flange is provided for direct attachment to machine frames, making the unit suitable for compact motion stages or packaging lines that rely on accurate closed-loop control.
This motor reaches a rated speed of 3000 rpm, while the length code 4 frame balances continuous torque output with space constraints. The front face follows a flange dimension of 91.3 mm, which helps simplify interchange with other IEC-sized motors. An optical EnDat feedback system in version 2.1 supplies single-turn and multi-turn position data at 13/12 bits of resolution, supporting fine incremental moves and absolute recovery after power loss. The encoder counts up to 4096 revs internally, removing the need for external homing switches on long-travel applications. A keyed shaft end transmits torque positively to couplings or pulleys, and the absence of an oil seal reduces axial friction in dry, cabinet-mounted installations. Because no holding brake is fitted, static load retention must be provided by the drive or by a mechanical lock when power is removed.
Connections exit the stator through an angled (swivel) plug system that terminates in a field-installable connector, allowing cable routing inside tight enclosures. The windings rely on self-cooling with free air circulation, so thermal limits are maintained by ambient airflow rather than by forced ventilation hardware. As a three-phase synchronous design, the motor delivers constant torque over a wide speed range and operates with sinusoidal current supplied by a matched inverter. The standard 8LSA build, combined with the keyed shaft and flange mounting, makes the motor suitable for conveyors, pick-and-place robots, or indexing tables that do not require a built-in brake or an oil barrier.
