Product Description:

B & R Automation produces the 8LSA25.R0060D100-0 as part of its 8LS Synchronous Motors series. The unit is a compact rotary servo motor intended to drive indexing tables, pick-and-place axes, and other motion modules inside automated machinery. By combining a lightweight stator package with a high pole-count rotor, the device converts electrical power into continuous, accurately controlled torque and supports precise position and velocity loops within a PLC-controlled environment.

The motor uses a flange that measures 58 mm, allowing direct attachment to small gearboxes or machine frames without adapter plates. Under nominal excitation, it can spin at up to 6000 rpm, a speed range that gives the system enough headroom for rapid acceleration profiles in short-stroke applications. Heat generated by copper losses is removed through self-cooling with free air circulation, so no external fan or liquid loop is required. Feedback for closed-loop control is delivered by a resolver, which supplies analog sine-cosine signals that tolerate vibration and electrical noise. Power and signal leads exit through an angled swivel connector, reducing cable bend stress when the motor is mounted on moving carriages. The motor also uses a length code 5 stator stack, a standard 8LSA configuration without reinforced bearings, and a mounting flange that supports front-face fastening.

The electrical section uses a three-phase synchronous winding, enabling high torque density while keeping current harmonics low. The unit has no holding brake, so mechanical clamping or drive torque must secure the axis during power-off states. Positional repeatability is supported by a maximum backlash error of 10 arcmin, which is suitable for medium-precision pick-and-place equipment. The output is provided through a shaft with key, and there is no oil seal, so the installation area should remain free of coolant spray or lubricating oil mist.
