Product Description:
The 8LSA75.DA030S100-3 is a three-phase synchronous motor developed by B&R Automation for the 8LS Synchronous Motors series. Within automated machinery, this unit delivers rotary motion directly to drive axes that require compact dimensions, encoder feedback, and simple wiring compatible with servo controllers. It carries the internal designation 8LSA and is supplied without a reinforced bearing, making it suitable for applications that do not impose elevated radial loads. The synchronous design supports precise torque regulation when the motor is paired with a compatible servo drive.
The motor reaches a rated speed of 3000 rpm, allowing precise velocity control across common servo drive output ranges. Position and speed are reported through an inductive EnDat feedback system, and the protocol operates at version 2.2 to provide digital diagnostics and electronic nameplate data. A flange dimension of 190 mm provides a broad mounting face for attachment to compatible gearboxes or machine frames. The flange mounting arrangement also allows the housing to be secured from the machine side without a separate foot-mounted base. Power, signal, and encoder conductors use a single-cable hybrid connection, reducing cable bulk and connector count compared with separate power and feedback leads. The encoder provides 19 bits of single-turn resolution without multi-turn storage, supporting fine position measurement within one mechanical revolution.
Thermal management relies on self-cooling with free air circulation, so the motor does not require an external blower or liquid-cooling jacket when adequate ambient airflow is available. Field wiring attaches through a sealed connector rather than fixed pigtails, allowing the cable to be disconnected without disturbing internal terminations. The motor has no holding brake, so drive torque or an external locking device must retain the load while the axis is stationary. The non-braked design also omits an oil seal, which reduces friction at the shaft interface. Length code 5 indicates the active stack length, while product revision 3 identifies the build revision. Output torque is transmitted through a shaft with a key, providing positive engagement with a compatible keyed coupling, pulley, or gearbox input.
