Product Description:

The 8LSA75.R0030D000-0 is a rotary motor manufactured by B&R Automation within the 8LS Synchronous Motors series. Supplied in the 8LSA standard build without a reinforced bearing, the unit serves as a drive element for positioning tasks in industrial robots, gantries, and conveyor systems. By combining a permanent-magnet rotor with electronic commutation, the motor converts drive current into regulated mechanical torque for closed-loop motion sequences in factory automation.

The motor uses a three-phase synchronous design, enabling sinusoidal current control without slip. At a rated speed of 3000 rpm, the rotor delivers constant velocity suited to standard servo inverter output frequencies. Heat is managed through self-cooling with free circulation, so no external blower or liquid circuit is required. A flange pattern of 190 mm centers the housing on machine frames and corresponds to the IEC mounting face. Rotor position feedback is generated through a resolver, allowing the drive to compute real-time angle and speed even in high-temperature or electrically noisy areas. The length code 5 housing balances torque density against overall motor weight, and the integrated connector interface simplifies cabling.

The motor has a smooth shaft for direct coupling to pulleys or couplings without keyways. Positional alignment is held within 10 arcmin, which is suitable for mid-range indexing duties. Installation uses a mounting flange, while power and feedback leads exit through an angled swivel connection to ease cable routing in tight cabinets. The motor is delivered without a holding brake, and the housing omits an oil seal because the application assumes a clean, dry environment. The standard bearing arrangement remains non-reinforced, which matches general-purpose servo loading instead of heavy radial loads.
