Product Description:

The 8LVA33.B1021D000-0 is a three-phase synchronous servo unit manufactured by B & R Automation and assigned to the 8LVA Three Phase Synchronous Motors series. Its type code also references the 8LV Servo Motor product series for configuration. The device converts drive current into controlled rotary motion for positioning, indexing, or velocity-regulated tasks in automated machines. An inductive absolute encoder and a battery-backed multi-turn counter allow controllers to recover shaft position immediately after power is restored, reducing cycle restart times.

The mechanical output reaches a nominal speed of 2100 rpm, allowing moderate-speed axes such as indexing tables or feed rollers to run directly from the shaft. Heat is dissipated through a self-cooling housing, eliminating the need for forced ventilation. Position feedback accuracy is held within ±120 arcsec, which suits medium-precision pick-and-place or packaging stations. The encoder side follows the EnDat 2.2 Inductive standard, so digital position, diagnostic, and electronic nameplate data travel on the same lines. Power and signal connections enter through a single hood with a built-in double angular swivel connector that can be rotated during installation to relieve strain.

The feedback chain delivers fine granularity because each single-turn revolution is resolved to 19/16 bits, and the multi-turn counter stores up to 65536 revolutions. Power conductors are isolated from encoder lines by separate encoder and power connections, reducing electrical noise on long cable runs. A smooth shaft mates with zero-backlash clamps, and because no oil seal is fitted, any required lubricant retention must be provided by the connected mechanics. The motor length and size are both coded 3. It has no holding brake, and functional safety hardware is absent, so external stop and safe torque-off circuits must be implemented.
