Product Description:

B&R Automation’s 8LSA25.R0060D100-3 is a servo motor from the 8LS Synchronous Motors series that drives rotary axes in packaging, assembly, and material-handling systems. The A identifier marks a standard build without reinforced bearings, and the motor converts inverter current into regulated torque and speed for accurate axis control. Resolver-based feedback lets the connected drive monitor rotor motion continuously, which supports stable positioning and controlled response during changing load conditions. Because the motor is intended for servo duty, it responds to drive commands with controlled acceleration and deceleration rather than simple fixed-speed rotation.

Its nominal speed limit is 6000 rpm, enabling direct coupling to fast tooling or conveyor rolls without external gearing. Heat is removed by a self-cooling with free circulation design that eliminates the need for forced-air ducting and keeps the installation simple. Position and velocity are detected by a resolver, which remains tolerant of electrical noise during industrial operation. The mounting interface uses a 58 mm flange, and the motor is supplied without a holding brake, so any holding force at standstill must come from the drive or external machine mechanics. Power and feedback are combined in a single molded connector, and the standard bearing arrangement supports responsive motion with low added inertia.

The wiring exits through an angled swivel connection, which helps route the cable within tight machine spaces and reduces stress on moving-axis loops. The connection style keeps strain relief inside the machine envelope, which is useful where moving parts leave little room for wide cable bends. Repeatable positioning is supported by 10 arcmin mechanical precision that matches the flange centering tolerance. A shaft with a key transmits torque securely, and the three-phase synchronous design provides smooth rotary output across the usable speed range. Length code 5 increases stack height compared with shorter motors in the same family, while product revision 3 marks the recorded revision level and the unit is built without an oil seal.
