8LVA23.R0030D027-0 by B & R Automation

B&R Automation manufactures the 8LVA23.R0030D027-0, a three-phase synchronous motor offered within the 8LVA Three Phase Synchronous Motors series. The unit is also classified in the 8LV Servo Motor product series and is compatible with standard servo drives. Used as a direct-drive element, the motor supplies consistent torque and speed for positioning axes and coordinated motion stages in automated assembly, packaging, and pick-and-place equipment.

The motor reaches a nominal speed of 3000 rpm, allowing control systems to execute rapid index moves without mechanical gearing. Positional repeatability is supported by an accuracy window of 10 angular minutes, which is the maximum deviation between the commanded and actual shaft angle when feedback is closed. Power, feedback, and brake conductors plug into a built-in double angular connector (swivel), and its rotation eases cable routing in tight machine frames. Signal segregation is preserved because the cable interface uses separated encoder and power connections, which reduces electromagnetic interference between high-current phases and low-level resolver lines. Size code 2 sets the frame dimensions and flange pattern used for this motor size. A resolver serves as the encoder system, providing analog sine-cosine feedback for servo drive commutation. The design omits a holding brake, so any power-off load retention must be handled by external clamping devices.

Thermal management relies on self-cooling, so heat is transferred through the housing surface without forced airflow. Length code 3 indicates an extended active stack that increases continuous torque capability while keeping the selected frame size. Application interfaces are simplified by a smooth shaft, which mates with clamp couplings or pulleys without keyways. The resolver element is RE-15-1-J04, matching the drive's excitation and sampling parameters. No oil seal is fitted, so the mounting position should exclude fluid spray zones or use external sealing if required for the duty cycle.
