Product Description:
B&R Automation manufactures the 8LSN57.E0022D300-0 as a member of the 8LS Synchronous Motors series. The motor serves as the primary drive element in automated machinery that requires precise torque and velocity regulation. It is suitable for indexing, conveying, and coordinated axis control in systems where repeatable rotary motion is important.
The motor uses a three-phase synchronous design and has a rated shaft speed of 2200 rpm, allowing direct coupling to gearboxes or loads that operate at moderate rotational speeds. Heat is removed through self-cooling, which uses the housing surface and surrounding airflow to dissipate thermal energy without an external fan. An increased-inertia rotor smooths changes in speed and can help stabilize motion when the connected load varies during operation. Mechanical attachment is provided by a mounting flange with a 142 mm square pattern, while length code 7 indicates the housing length used for installation planning. An integrated standard holding brake keeps the axis stationary during power loss or planned machine stops. The motor also has a keyed shaft end for positive torque transfer, no oil seal for reduced shaft drag, and an angled swivel cable outlet that supports strain-relieved cable routing. It uses the standard bill-of-material configuration for this model.
Position feedback is provided by an optical EnDat encoder that uses protocol version 2.1 to communicate with the drive. The bidirectional serial interface transmits absolute position information for closed-loop position and velocity regulation. The encoder provides single-turn feedback with 13-bit resolution for each revolution and no multiturn turn-count data. Power and signal cables use the angled outlet, helping the conductors fit within restricted installation spaces while reducing excessive bending near the motor housing. The swivel mechanism allows the cable direction to be adjusted to match the available routing path without changing the motor’s mounting position.
