8LSA66.EA022D000-3 by B & R Automation

B&R Automation manufactured the 8LSA66.EA022D000-3. The motor belongs to the 8LS Synchronous Motors series and is a three-phase synchronous unit used for coordinated axes and positioning modules in industrial automation. Inside a drive system, it converts electrical power into controlled torque and speed for pick-and-place gantries, packaging machinery, and material-handling stages.

It reaches a rated speed of 2200 rpm, providing medium-speed motion profiles for conveyors and format adjustments. A flange dimension of 190 mm sets the mounting pattern and allows the frame to fasten rigidly to machine bases. Heat is removed through self-cooling with free air circulation, so no external blower or liquid circuit is required. Position feedback uses an EnDat 2.1 inductive encoder that resists contamination and supplies absolute data to the drive controller. The encoder offers 19/0 bits of resolution, which means it provides 19 bits of single-turn data and no multi-turn counting. A smooth shaft end mates with couplings that transmit torque without a key, while length code 6 identifies the active magnetic stack used for this torque class.

Cabling exits through an angled connection that can swivel, which helps with strain relief in compact cabinets. Power and feedback share a keyed connector interface for secure cable attachment and orderly routing. Because there is no holding brake, the application must secure loads through the drive or external clamps during power-off states. The motor does not include an oil seal, so the installation area should stay clear of coolant splash. The configuration uses a standard bearing arrangement without reinforcement, and the single-turn encoder format suits indexing tasks that return to a reference each cycle. The motor is listed as product revision 3 and uses the 8LSA designation.
