Product Description:

The 8LVA22.R0030D200-0 is a three-phase synchronous motor produced by B&R Automation for the 8LVA Three Phase Synchronous Motors series. It serves as the rotary actuator in industrial automation cells, delivering closed-loop speed and torque control to indexing tables, feeders, and packaging modules where fast response and precise positioning are required. The permanent-magnet design supports responsive acceleration and controlled rotary motion when the motor is paired with a compatible servo drive. The motor has size 2 and length 2, matching the corresponding mechanical envelope in the 8LV servo motor family.

The motor reaches a nominal speed of 3000 rpm, allowing integration with gear stages that require high input velocity. Positional repeatability remains within 10 angular minutes, making the motor suitable for applications that require consistent positioning across repeated cycles. Thermal management relies on self-cooling, which allows heat to dissipate through the frame without external air or liquid circuits. This cooling method reduces the number of auxiliary components needed around the motor and leaves nearby machine space available for cables and mounting hardware. Power and feedback conductors terminate on a built-in double-angle connector, and the swivel design eases cable routing in confined machine spaces. A permanent-magnet holding brake supplies 2.2 Nm of static torque, helping vertical axes remain stationary when motor power is removed. No oil seal is fitted, so the installation area must remain free of pressurized lubricants that could reach the shaft opening.

Rotor position is sensed by a resolver, which provides analog feedback for closed-loop control under elevated temperatures and vibration. The resolver model is RE-15-1-J04, and it delivers sine-cosine signals that allow the connected drive to determine rotor angle throughout operation. The wiring harness uses separate encoder and power leads, reducing electromagnetic interference between the high-current motor phases and the low-level feedback signals. Keeping these circuits apart also supports stable signal transmission when the cables follow the same general route through the machine. Motion is transferred through a smooth shaft, allowing the motor to connect to clamp-style or shrink-disc couplings without a keyed joint. This shaft arrangement supports a close mechanical fit while avoiding the clearance associated with a key and keyway.
