8LSA73.E1022D200-0 by B & R Automation

B&R Automation manufactures the 8LSA73.E1022D200-0 within the 8LS Synchronous Motors series. This unit is a three-phase synchronous motor that serves as a drive element for coordinated motion axes in industrial automation. It carries the internal designation 8LSA and uses the standard configuration without a reinforced bearing, so its mechanical layout stays compact while still supporting a mounting flange interface. The motor uses a smooth shaft for direct coupling, and the absence of an oil seal means the application must provide external protection if liquid exposure is possible.

The motor's rated speed is 2200 rpm, giving machine builders a fixed performance point for sizing gear ratios and inverter output frequency. A flange dimension of 190 mm determines the bolt circle and keeps installation interchangeable with other motors in the same frame class. Position feedback relies on optical EnDat, and protocol revision 2.1 allows digital transmission of absolute position data to modern servo drives. The feedback resolution is 13/12 bits for single-turn and multi-turn counting, which improves velocity control and repeatability. Power and feedback conductors terminate through a connector, and a length code of 3 identifies the stator stack depth used for this torque class.

The motor includes a standard holding brake so vertical or indexing loads remain fixed when the drive is de-energized. Cabling exits the housing with an angled swivel orientation, simplifying routing inside tight cabinets. Heat is removed by self-cooling through free air circulation, eliminating the need for external blowers. Encoder logic supports multi-turn (4096 revolutions), letting controllers recover absolute position after power loss. The connector arrangement keeps the electrical interface consolidated at the motor housing, which helps when cable routing space is limited.
