8LSA46.DA030S200-3 by B & R Automation

The 8LSA46.DA030S200-3 belongs to the 8LS Synchronous Motors series produced by B&R Automation. It is a three-phase synchronous motor intended for servo axes and positioning tasks in automated machinery, where precise torque generation and compact installation footprints are important. This version uses the standard 8LSA construction rather than a reinforced-bearing arrangement, so it suits general-purpose motion duties that do not place unusually high radial loads on the shaft. That makes it suitable for applications that need repeatable positioning without the added bearing support used for heavier side loads.

The motor reaches a rated speed of 3000 rpm, enabling direct coupling to moderate-speed transmission stages without overspeeding the rotor. Power and feedback signals are routed through a single-cable hybrid interface that terminates in a molded connector, which reduces cable routing complexity and keeps the motor connection area compact. Thermal regulation relies on self-cooling with free air circulation, removing the need for external blowers. Rotor position is monitored by an Inductive EnDat encoder that operates on version 2.2 protocol and provides a 19/0 bit resolution for single-turn and multi-turn data, supporting tight loop control. The mounting interface uses a 100 mm flange, while the smooth-face housing uses length code 6 and product revision 3.

A standard holding brake is integrated to keep the load in position when power is removed, which is useful on vertical or stationary axes. The shaft exits the housing as a smooth shaft, favoring clamp couplings or friction hubs over keyed joints. Because there is no oil seal, the motor is best suited to clean environments or to installations that provide external sealing around the shaft area. This arrangement supports use in modular machine platforms where compact dimensions and straightforward axis integration are important.
