Product Description:

The 8LSA26.R0045D100-3 is a three-phase synchronous motor manufactured by B&R Automation as part of the 8LS Synchronous Motors series. Designed for industrial automation, the unit converts electrical power into controlled rotation for indexing stations, gantry axes, and other motion tasks that demand coordinated servo performance. Its electromagnetic design supports high dynamic response while remaining compatible with matching AC drive modules, allowing builders to implement synchronized multi-axis systems in packaging, assembly, and material-handling equipment.

At a rated speed of 4500 rpm, the motor can support high-throughput processes while remaining within the thermal envelope created by its self-cooling with free circulation airflow design. The front face carries a flange diameter of 58 mm, giving a standard interface for compact gearboxes and couplings. Electrical power and feedback are routed through a connector seated in an angled swivel orientation, simplifying cable runs inside tight machine enclosures. Rotor position is detected by a resolver, which maintains stable commutation. The motor uses a length code 6 stator stack, and product revision 3 marks this build version. Because the 8LSA configuration omits a reinforced bearing and does not include an additional oil seal, external axial loads and ambient contamination limits must be considered.

In terms of mechanical integration, the motor is delivered with a mounting flange, so it can be fastened directly to a machine frame without auxiliary brackets. A machined shaft end comes with a key, allowing torque to be transferred to pulleys or couplings without slip during acceleration and deceleration. Static positioning repeatability is maintained within 10 arcmin, which meets the accuracy requirements of most mid-range assembly lines. For safety or load-holding scenarios, the motor has no internal brake, so external actuators must provide holding force when needed.
