8LSA25.R0060D300-3
The 8LSA25.R0060D300-3 is a synchronous servomotor produced by B&R Automation within the 8LS Synchronous Motors series. Designed for closed-loop positioning and velocity control, the unit mounts directly to machine frames through its flange. It drives rotary axes that require rapid acceleration and accurate speed tracking in automated cells. This layout suits compact motion systems where precise response is needed without adding separate transmission components. It is well suited for compact handling equipment, indexing tables, and other machinery where the motor must fit near the driven load.
This motor is a three-phase synchronous model, so it operates from a sinusoidal three-phase inverter while maintaining a fixed relationship between electrical frequency and mechanical speed. Its nominal operating point is 6000 rpm, which supports fast cycle times in packaging, pick-and-place, and indexing applications. Heat is removed through self-cooling with free circulation, so no external fan or liquid circuit is required. A 58 mm flange helps align the motor on the machine plate, and the power and feedback cabling exits through an angled swivel connector that simplifies routing inside compact enclosures. The motor also has a keyed shaft for positive torque transfer, a plug-style connection interface, and no oil seal to reduce friction at high speed. The direct plug connection helps keep installation tidy in confined machine spaces.
The motor uses a resolver for feedback, and mechanical repeatability is held within 10 arcmin for consistent positioning. During power-off states, a standard holding brake secures the load to help prevent back-driving on vertical axes. It has a length code 5, which balances torque output with overall package length. The product is supplied in revision 3 form, uses the 8LSA configuration without reinforced bearings, and is intended for flange mounting rather than supplemental foot mounting.
