Product Description:
The 8LSA45.ee030ffgg-3 is a servo-class motor manufactured by B&R Automation within the 8LS Synchronous Motors series. The unit is intended for integration into automated machinery where fast response and repeatable positioning are required, such as pick-and-place stations, indexing tables, and format-adjustment equipment. It converts electrical power from a controlled inverter into mechanical rotation through a permanent-magnet rotor and stator winding set. This operating principle allows multiple axes to remain synchronized and helps machinery maintain consistent production rates under variable load conditions.
Power and feedback lines terminate at a single connector, reducing the number of separate connection points and helping prevent wiring errors. Thermal regulation relies on self-cooling with free air circulation, which dissipates heat through the housing without external blowers or liquid cooling loops. The front face has a square pattern with a flange dimension of 100 mm, allowing the motor to fit compatible machine interfaces. The housing attaches to the machine through a mounting flange, while the centered shaft transfers torque to the connected mechanical load. Under rated excitation, the rotor reaches a shaft speed of 3000 rpm. This speed is suitable for many servo applications using vector-controlled frequency conversion on common industrial power systems.
The motor uses the series code 8LSA and a length index of 5, indicating the selected active stack height and overall motor length. Its electromagnetic design uses a three-phase synchronous arrangement, so the rotor turns in step with the rotating magnetic field generated by the stator. The permanent-magnet rotor eliminates slip during synchronous operation, while sinusoidal drive current provides controlled torque across the operating range. The motor is product revision 3, with encoder compatibility and mechanical tolerances aligned with the corresponding generation of 8LS motion components. Its servo-oriented design supports closed-loop control of shaft position, rotational speed, and output torque when connected to a compatible inverter and feedback system.
