Product Description:
The 8LSA46.DB060S000-3 is a three-phase synchronous servo motor produced by B & R Automation as part of the 8LS Synchronous Motors series. With its 8LSA designation and product revision 3, the unit uses the standard configuration without reinforced bearings, making it suitable for automated machinery with moderate radial loads. The motor converts electrical power into precise rotary motion for axes that require high-speed positioning in industrial automation cells. Its compact design supports installation in machinery where available mounting space is limited.
The motor has a rated speed of 6000 rpm, providing the velocity required by fast packaging spindles and other high-speed axes. A flange dimension of 100 mm provides the interface size for direct mounting to compatible gearboxes or machine plates. Thermal management uses a self-cooling design that relies on free air circulation around the housing, eliminating the need for forced ventilation hardware. Position feedback is provided by an inductive encoder that supports EnDat 2.2, permitting high-speed serial transmission of absolute position data to the B & R drive. The encoder has a 19/12-bit resolution, providing 19-bit single-turn position data and 12-bit multi-turn position data to the controller.
The encoder stores absolute position data across 4096 revolutions, allowing the controller to retain axis position information after a power cycle. Power, feedback, and brake conductors are combined in a single-cable hybrid connection with a molded connector, reducing the amount of separate wiring required between the motor and drive. Because the motor has no holding brake, vertical axes require an external mechanical lock when the drive is disabled. A smooth shaft minimizes the imbalance associated with a keyway and supports attachment through a suitable clamping coupling. The shaft is supplied without an oil seal, so the installation should prevent lubricants or contaminants from reaching the bearing area. Length code 6 indicates the active stack height used for this motor configuration.
