Product Description:
The 8LSA55.EB045D000-3 is a three-phase synchronous motor produced by B & R Automation within the 8LS Synchronous Motors series. Intended for servo axes in industrial automation, it converts controlled current from a drive into repeatable torque and speed. The motor supports motion in pick-and-place stations, feeders, and packaging machinery where accurate indexing and controlled acceleration are required. Its synchronous operation allows the connected servo drive to regulate the shaft in response to position and speed commands from the machine controller.
The motor operates at speeds up to 4500 rpm, enabling rapid indexing without requiring an oversized drive. A flange face measuring 142 mm provides the mounting interface and keeps the stator concentric with the connected load. Heat is removed by a self-cooling design that relies on free air circulation, so no external blower or liquid circuit is required. Power and feedback conductors exit through an angled swivel connector that simplifies cable routing in confined installation spaces, and the mating hardware uses a sealed industrial connection. The motor has a smooth shaft for couplings that clamp directly onto the journal. Length code 5 indicates the stack height, and the motor uses the standard bearing arrangement without reinforcement. The unit is supplied without a holding brake, so an external mechanism or drive-applied torque must secure stationary loads. There is no oil seal at the shaft, which reduces seal maintenance in lightly contaminated installations.
Position feedback is generated by an inductive EnDat encoder that communicates over protocol version 2.1. The encoder provides 19-bit single-turn resolution and 12-bit multi-turn resolution. Its multi-turn range of 4096 revolutions preserves the absolute position count through repeated shaft rotations, supporting position recovery after power cycles. Mechanical attachment uses a mounting flange, allowing direct connection to a gearbox or machine frame while maintaining alignment with the driven equipment. Product revision 3 identifies the revision level of this motor configuration.
