Product Description:

The 8LSA45.EA030D300-0 is a three-phase synchronous motor built by B&R Automation within the 8LS Synchronous Motors series. As a standard option in this range, it provides rotary actuation for axes that need precise velocity and position control in automated machinery such as packaging stations and pick-and-place modules. The model functions as a drive component that converts electrical power into controlled mechanical rotation for coordinated multi-axis motion.

This motor reaches a rated speed of 3000 rpm, allowing direct coupling to gearboxes or belt drives without overspeeding common automation peripherals. A mounting flange measuring 100 mm aligns the housing to machine frames and positions the shaft concentrically with the driven load. Heat produced by copper losses is removed through a self-cooling with free circulation design, so no external fan or liquid circuit is necessary. For feedback, an Inductive EnDat encoder supplies absolute position information, and it supports protocol level 2.1 for bidirectional communication and electronic nameplate data exchange.

A standard holding brake locks the shaft when power is removed, maintaining axis position during emergency stops or vertical load pauses. Power and feedback leads exit through an angled swivel connector interface, which helps strain-relief routing in tight enclosures while keeping the connection hardware sealed. The encoder delivers a resolution of 19/0 bits, indicating 19 bits for single-turn measurement and 0 bits for multi-turn data, which matches the single-turn capability of this variant. Drive torque is transmitted through a shaft end equipped with a key. The motor is supplied without reinforced bearings, no oil seal is present, and length code 5 indicates the overall body extension used for the internal stator stack.
