8LSA34.R0030C000-0 by B & R Automation

The 8LSA34.R0030C000-0 is an AC servo motor manufactured by B&R Automation and included in the 8LS Synchronous Motors series. Within its internal coding, it carries the designation 8LSA and follows the standard configuration that omits a reinforced bearing. The unit is built around length code 4 and mounts by means of a dedicated flange, so it can be integrated directly onto machine frames or gearheads. In industrial automation, the motor converts drive power from a servo amplifier into controlled rotary motion for packaging, printing, and pick-and-place axes.

The motor reaches a rated operating velocity of 3000 rpm, allowing coordinated motion with 1 kHz-class control loops. Its interface face width conforms to a 91.3 mm flange dimension, providing a predictable bolt circle for mechanical alignment. Heat is evacuated through self-cooling with free air circulation, so no fan or liquid circuit is required. Rotor position is returned by a resolver, an analog transducer that withstands electrical noise and provides stable feedback. The system repeatability is limited to 10 arcmin, which is the maximum shaft position deviation during load reversal. Power and feedback conductors exit through a straight top connector, and this connection direction simplifies vertical cable routing inside compact cabinets.

As a three-phase synchronous machine, the stator produces a rotating field that tracks the drive current and maintains precise torque even at low speed. There is no holding brake, so any static load must be restrained by the drive or by an external clamp when power is removed. The output is a smooth shaft, and the front end has no oil seal, a combination that minimizes friction and suits coupling methods that rely on shrink fits or clamping hubs.
