8LVA33.R0015D000-0 by B & R Automation

The 8LVA33.R0015D000-0 is a three-phase synchronous motor produced by B&R Automation within the 8LVA Three Phase Synchronous Motors series. It is used as a drive element in automated machinery where closed-loop motion control is required for positioning, indexing, or continuous rotary tasks. When paired with compatible B&R servo amplifiers, the unit converts electrical energy into mechanical torque while returning rotor position information for coordinated multi-axis operation in production lines and material-handling cells.

The rotor has a nominal speed of 1500 rpm, which suits conveyor sections, rotary tables, or pump shafts. Positional accuracy is held within 10 angular minutes, allowing the controller to maintain repeatable stopping positions without a secondary encoder. Heat is removed through self-cooling, eliminating the need for forced airflow or liquid circuits. Feedback is delivered by a resolver, an analog device that tolerates vibration and temperature swings better than many optical encoder systems. Power and signal conductors are routed separately through a separate encoder and power interface, which helps reduce electromagnetic interference during high-current switching. Field wiring connects through a built-in double angular connector that swivels, so the cable bundle can be routed in either direction inside compact enclosures.

The motor uses Motor length 3 together with motor size 3, giving it mid-range inertia for medium torque demands without oversizing. Inside the stator, the RE-15-1-J04 resolver provides the transformation ratio expected by B&R drives. A smooth shaft is supplied for clamp-hub couplings, so no keyway machining is required on the mating element. The motor does not include a holding brake, so static load retention must come from the drive or from external locking hardware, and the lack of an oil seal limits use to environments where lubricant migration is not a concern.
