Product Description:
The 8LVA33.R0021D200-0 is a three-phase synchronous servo motor developed by B&R Automation for the 8LVA Three-Phase Synchronous Motors series. Classified under the 8LV servo motor architecture, it converts drive amplifier current into controlled mechanical motion with integrated feedback. The device is intended for packaging machines, material-handling robots, and assembly stations where coordinated axes must accelerate, decelerate, and hold position with electrical precision. Its synchronous design supports regulated torque and speed when paired with a compatible servo drive.
It reaches a nominal shaft speed of 2100 rpm, providing a balance between speed and torque for medium-duty tasks. When power is removed, a permanent-magnet brake rated at 4.0 Nm locks the rotor and prevents vertical or overhung loads from drifting. Positioning error is limited to 10 angular minutes, supporting moderate repeatability requirements without an external encoder. Electrical terminations enter through a built-in swiveling double-angle connector, which can be rotated to relieve cable stress during installation. Ambient airflow over the finned housing provides self-cooling operation, so no fan or liquid circuit is required. The electromagnetic stack has a length of 3. Because the motor has no oil seal, lubricants must be kept away from the front bearing.
Rotor position is measured by a resolver pickup, model RE-15-1-J04, which withstands high temperatures and delivers analog sine-cosine signals to the drive. Wiring uses separate encoder and power cables to isolate low-level feedback signals from motor phase currents. Torque is transferred through a smooth shaft, allowing backlash-free clamp couplings in pick-and-place equipment or indexing tables. The size 3 frame provides a midrange mounting footprint that supports consistent bracket and housing dimensions across compatible installations. The resolver supplies the drive with the rotor-angle information needed for electronic commutation and closed-loop positioning. The cable arrangement also helps reduce electrical interference between the feedback and power circuits during operation.
