8LSA44.EB022D000-3 by B & R Automation

The 8LSA44.EB022D000-3 is a three-phase synchronous motor manufactured by B & R Automation within the 8LS Synchronous Motors series. Identified by the 8LSA configuration, it uses a standard bearing set without reinforcement. Heat is removed through self-cooling with free air circulation, so the motor does not require forced ventilation. It is intended to supply tightly regulated rotary motion for conveyors, pick-and-place axes, and other automated machinery in industrial plants. The design suits applications that need consistent positioning and stable speed control during repeated operating cycles.

The motor's rated speed is 2200 rpm, allowing servo controllers to match electrical frequency to the motor's mechanical output. A flange dimension of 100 mm sets the mounting face, so machine frames can accept the unit without adapter plates. Position feedback comes from an Inductive EnDat 2.1 encoder that exchanges digital position data and motor parameters over a bidirectional link. Its native resolution is 19/12 bits, yielding 524,288 positions per turn and absolute tracking over 4096 revolutions. Because the motor has no holding brake, the drive system must maintain torque or use external locking when power is removed. The motor uses a smooth shaft to avoid keyway stress, and it has no oil seal, which lowers friction at the output journal.

The mechanical outline follows the mounting flange format with length code 4, providing rotor depth suited to medium-inertia loads. Electrical and feedback conductors route through an angled swivel interface that helps reduce cable bend radius, and the housing uses a pluggable connector interface for compact wiring access on multi-axis machines without requiring a straight cable exit behind the housing. The motor is identified as product revision 3. This revision marks the documented version of the motor used within the product line.
