8LSA35.R2030D000-3 by B & R Automation

B & R Automation's 8LSA35.R2030D000-3 belongs to the 8LS Synchronous Motors series and is classified as a three-phase synchronous motor. Delivered in the 8LSA standard configuration, it is intended for servo axes where compact dimensions and stable torque are required. Within an automated line, the motor pairs with a matching inverter to provide tightly controlled rotary motion for feeders, indexing tables, or compact machining modules. Its compact format also suits machines that need responsive motion without using a large motor frame.

The electrical section is designed for a rated speed of 3000 rpm, allowing the drive controller to maintain high throughput without overspeeding the mechanical load. Rotor position is returned by a resolver, a passive sensor that provides noise-immune sine-cosine feedback for closed-loop control. The motor has a flange face of 91.3 mm, which matches the 8LSA frame size used for this power range. Heat is removed by self-cooling with free air circulation, so airflow around the housing is sufficient and no external blower or liquid jacket is needed. Power and feedback leads exit through an angled swivel connector arrangement, which permits cable routing in tight cabinets while reducing strain on the terminals. This combination supports stable operation on compact axes that cycle frequently during normal production.

The motor has a smooth shaft, which simplifies coupling to gearboxes or belt pulleys that rely on interference fits rather than keys. Positioning repeatability is 6 arcmin, which is suitable for mid-accuracy pick-and-place or metering tasks. Installation relies on a rigid mounting flange that handles axial reaction forces without additional feet. The motor is built to Revision 3. Length code 5 balances rotor inertia against torque density, while the absence of an internal brake reduces mass during acceleration and deceleration. The motor is supplied without an oil seal and with a standard connector set, and it also uses the no reinforced bearing configuration. This layout is appropriate for clean machine areas where external holding or sealing is handled elsewhere in the system.
