Product Description:

The 8LVA22.B1030D300-0 is a three-phase synchronous servo motor built by B&R Automation for the 8LVA Three Phase Synchronous Motors series. It serves as a compact drive element for positioning tasks in automated machinery, where closed-loop motion must be repeated precisely and without frequent maintenance interruptions. This model reaches a nominal speed of 3000 rpm, allowing direct coupling to gearless axes that demand moderate throughput.

Feedback is provided by an EnDat 2.2 inductive encoder, and its single-turn angular error is limited to ±120 arcsec, enabling accurate contouring when the drive is interpolated across multiple axes. The encoder generates 19/16 bits of single-turn and multi-turn position data, allowing the controller to resolve fine increments while continuing to track the overall mechanical cycle. A permanent-magnet holding brake delivers 2.2 Nm of static torque, so vertical loads remain stationary whenever system power is removed.

The multi-turn design can record up to 65,536 revolutions, and that count is retained by a battery-backed supply, which allows the absolute position to survive plant power outages. Thermal management relies on self-cooling, allowing the housing to dissipate heat without external blowers or liquid circuits. A keyed shaft provides secure torque transfer to a coupling or driven mechanism. Encoder and power conductors exit through separate cables, and a built-in double angular swivel connector simplifies routing inside moving cable chains. The unit has motor size 2 and length code 2, providing a compact housing for space-constrained machinery. It does not contain an oil seal because it is intended for a dry operating environment. The motor does not include functional safety channels, so the machine control system must provide the required external safety functions.
