8LSA66.EB022D300-1
The 8LSA66.EB022D300-1 is a three-phase synchronous motor built by B & R Automation and belongs to the 8LS Synchronous Motors series. It is a standard 8LSA configuration without a reinforced bearing, intended for positioning and velocity-control tasks on machine-tool axes, packaging equipment, and general-purpose gantries. Its synchronous design supports controlled torque delivery and repeatable motion in automated equipment that depends on closed-loop motor feedback. The motor combines a compact housing with integrated feedback and a mounting flange, allowing it to be fitted directly to precision gearboxes or driven loads where accurate rotary motion and stable response are required.
During continuous operation, the shaft reaches a rated velocity of 2200 rpm, which suits moderate-speed axes such as indexing tables and vertical actuators. Thermal management relies on self-cooling through free circulation, so the housing dissipates heat without an auxiliary blower. The square mounting face measures 190 mm, providing a rigid interface for machine mounting while keeping the frame compact. Rotor position is reported through an Inductive EnDat sensor that works with EnDat version 2.1, allowing absolute position capture at power-up. A standard holding brake is integrated to secure the axis when supply power is removed.
The wiring exits the stator through an angled swivel connection, which helps reduce cable strain in tight cabinet layouts or on moving axes. Power and feedback lines share a single connector, reducing cable clutter at the motor interface and keeping the connection point compact. The encoder provides a 19/12-bit resolution data stream and supports multi-turn 4096 rev capability, so the controller can track position across multiple revolutions without external homing after every restart. Length code 6 indicates the active stack height, and the shaft end includes a key for torque transmission. This variant does not include an oil seal, so applications that require an external barrier should account for that at the machine interface.
