8LSA45.R0030D000-0 by B & R Automation

B&R Automation manufactures the 8LSA45.R0030D000-0 within its 8LS Synchronous Motors series. The device is a compact three-phase servo motor intended for positioning, indexing, and constant-speed duties on assembly cells, gantry axes, and transport modules. Its compact housing helps it fit installations where space is limited. By producing synchronous torque that stays locked to the stator field, the motor allows the controller to generate accurately programmed motion profiles for industrial automation lines.

The flange of 100 mm sets the mechanical interface, letting the motor bolt directly to standard gearheads or machine frames without adapter plates. Under rated excitation, the rotor reaches 3000 rpm, so a typical inverter can deliver nominal power while maintaining field orientation. A resolver feedback device supplies position signals that remain reliable under vibration and elevated ambient temperature. Heat is removed through self-cooling, using free air circulation across the housing ribs and eliminating external blowers. Cabling exits through an angled swivel connection, which eases routing in tight enclosures and maintains strain relief. The standard 8LSA configuration omits reinforced bearings, while length code 5 indicates an elongated active stack for greater continuous torque. A connector interface also allows tool-free electrical disconnection.

Machine builders secure the unit by its mounting flange, and the 8LSA45 designation identifies the frame size used in applications with limited installation depth. The motor uses a three-phase synchronous design, which eliminates rotor slip and supports closed-loop control that keeps positioning error within 10 arcmin. Because a holding brake is not present, vertical or overhung loads must be locked externally when the drive is disabled. The lack of an oil seal limits use to dry areas or to housings with additional protection. A smooth shaft eases coupling alignment, minimizes fretting, and supports backlash-free clamp hubs for accurate torque transmission.
