Product Description:
The 8LVA23.B1030D27-0 is a three-phase synchronous motor manufactured by B&R Automation for the 8LVA Three Phase Synchronous Motors series. It is used to drive precision axes in automated machinery where coordinated positioning and velocity control are required. The motor converts electrical power into controlled rotary motion for applications such as conveyors, indexing tables, and handling systems. Closed-loop operation allows a compatible servo drive to regulate the shaft position and speed as machine loads change.
The motor delivers a nominal speed of 3000 rpm, allowing direct coupling to gearless mechanisms that operate at conveyor or spindle speeds near this value. Position feedback is provided by an EnDat 2.2 inductive encoder with 19-bit single-turn and 16-bit multi-turn word lengths, providing high digital granularity over each mechanical revolution. The shaft position error remains within ±120 arcsec, supporting repeatable pick-and-place and indexing tasks. Encoder and power leads exit through separate interfaces, while the built-in double angular swivel connector simplifies cable routing in confined machine spaces. The smooth shaft end mates with friction or clamp couplings without requiring a keyed connection. Internal gearing supports multi-turn position counting across successive shaft revolutions. The motor has length code 3, and its swivel cable outlet maintains strain relief when the connector orientation is adjusted.
A battery-backed absolute position store tracks up to 65,536 rotations, allowing the control system to retain position information after a power loss without repeating a homing cycle. A permanently engaged holding brake provides 2.2 Nm of static torque to secure vertical loads when the drive is disabled. Thermal management relies on self-cooling, so the housing surface dissipates heat without external fans. This cooling method simplifies installation for machines designed around motor size 2 and avoids the maintenance associated with forced-air equipment. The motor does not include integrated functional safety, so any required safety functions must be provided elsewhere in the machine control system. It also does not have an oil seal, and applications exposed to lubricants may require additional shaft sealing to prevent fluid from reaching the bearing area.
