8LSA35.EA030D200-0 by B & R Automation

The 8LSA35.EA030D200-0 is a three-phase synchronous motor manufactured by B&R Automation and supplied within the 8LS Synchronous Motors series. As a rotary drive element, it converts electrical energy into controlled torque and speed, allowing precise axis movement in packaging machines, pick-and-place stations, and other automated assemblies. The design follows the 8LSA configuration that omits reinforced bearings, focusing on compact size while still meeting general-purpose motion requirements in industrial automation.

This motor delivers a rated shaft velocity of 3000 rpm, which is its continuous operating speed under nominal load and voltage. Heat produced by copper losses is removed through a self-cooling method that relies on free air circulation, eliminating the need for external blowers. A mounting flange with a face size of 91.3 mm centers the housing and provides repeatable alignment on machine frames. Power, brake, and feedback conductors exit through an angled swivel connector orientation, which reduces cable bend stress in dynamic installations. Position and speed feedback are generated by an Inductive EnDat encoder, and protocol version 2.1 supports bidirectional communication with the connected drive.

A standard holding brake is integrated to keep the load stationary when power is removed, which is useful on vertical or suspended axes. The shaft end is a smooth shaft, allowing backlash-free clamping hubs or rigid couplings to be fitted without keyways. The feedback system provides a resolution of 19/0 bits, indicating 19-bit single-turn measurement with no multi-turn count. The absence of an oil seal means applications exposed to lubricants must use external sealing. Length code 5 sets the active stack height, and the connector mates directly on the mounting flange without hard-wired terminations.
