Product Description:
The 8LCA33.R0A67D102-0 is a three-phase synchronous motor manufactured by B & R Automation within the 8LS Synchronous Motors series. The internal designation for this unit is 8LSA. It serves as a rotary servo element that converts drive controller output into precise mechanical motion for automated machinery, packaging equipment, and assembly systems. Its synchronous operation supports controlled torque and speed when paired with a compatible servo drive.
The motor bolts to equipment through a flange measuring 91.3 mm across, providing a fixed reference for frame alignment. Heat is removed by a self-cooling system with free air circulation, so no external fan or liquid circuit is required. Normal airflow around the housing helps transfer heat away from the stator during operation. Positional accuracy is maintained to 10 arcmin, making the motor suitable for indexing tables and moderate-precision axes. Rotor position data is supplied by a resolver, allowing the controller to close the feedback loop in electrically noisy environments. Power and feedback leads exit through an angled swivel connector arrangement, which reduces cable strain during installation in tight enclosures. The connection hardware uses a sealed circular interface, while the length code 3 stator stack provides mid-range torque for this motor family.
Mechanical coupling to gearboxes or pulleys is handled by a keyed shaft, which provides positive torque transmission without slipping. Structural attachment uses a mounting flange for secure alignment with the connected machinery. The motor is supplied with no holding brake, so static load retention must be managed by the drive or an external brake module. The absence of an oil seal means the shaft opening is not intended to exclude fluids, so the motor should be protected from direct oil spray. Resolver pins and power contacts are integrated into the connector system to keep the electrical interfaces organized. The free-circulation cooling path must remain unobstructed to maintain effective heat transfer around the housing during continuous operation.
