Product Description:

The 8LSC5A.R0030D000-0 is a rotary servo motor manufactured by B&R Automation for the 8LS Synchronous Motors series. It drives positioning, indexing, and continuous-duty axes on assembly lines, packaging cells, and CNC equipment. By converting three-phase electrical power into controlled torque, the unit partners with ACOPOS drives to move loads precisely across its speed band. Its compact frame supports machine-side or panel mounting while maintaining thermal stability under demanding cycles.

The motor body follows the 8LSC designation, indicating standard construction without reinforced bearings, and carries length code A for the shortest stator stack in this frame. A flange diameter of 142 mm sets the mechanical interface and mates with ISO gearbox patterns. Integrated cooling uses a built-in fan assembly that moves air along the housing to hold winding temperature during continuous duty. At a rated speed of 3000 rpm, the rotor delivers constant torque while allowing overspeed for rapid indexing. Position feedback is provided by a resolver, an analog sensor that is resistant to electrical noise. Closed-loop accuracy benefits from a precision of 10 arcmin, limiting cumulative error in multi-axis systems. Power and signal connections exit through one connector, which streamlines cabling.

As a three-phase synchronous machine, the rotor’s permanent magnets synchronize with stator currents to provide steady torque across varying loads. The electrical leads exit via an angled swivel connection, permitting tight cable bends when the motor is mounted close to other hardware. Because there is no holding brake, the axis must rely on static drive torque or external locks to remain stationary during power-off states. The shaft interface is a smooth shaft, supporting backlash-free clamp hubs and minimizing keyway stress. An oil seal is not included, which lowers rotational friction and suits clean environments where lubricant migration is not critical.
