Product Description:

B&R Automation's 8LVA33.B1015D000-0 is a three-phase synchronous motor in the 8LVA Three Phase Synchronous Motors series. It acts as an electromechanical drive element that delivers controlled rotary motion to conveyors, indexing tables, or articulated axes in industrial automation lines. The design couples a permanent-magnet rotor with a digital feedback interface so that the associated servo amplifier can regulate current and position in real time. It belongs to the manufacturer’s medium-frame class and is intended for applications where repeatability, compact dimensions, and low maintenance are important. This arrangement supports repeatable acceleration and stopping in machines that cycle frequently and must return to the same position throughout the day.

At a nominal speed of 1500 rpm, the unit delivers rated torque within its size 3 frame and motor length class 3. Position feedback is provided by a ±120 arcsec absolute encoder that uses the EnDat 2.2 Inductive interface. The device supplies 19/16 bits of single-turn and multi-turn resolution through a built-in double angular connector that can swivel to relieve cable strain. Power conductors and encoder lines exit on separate plugs, a separation that helps minimize conducted noise. Functional safety hardware is not included, so external circuitry must handle STO and emergency-stop tasks. A smooth shaft end mates directly with couplings, and the lack of an oil seal means the bearing zone should be protected from liquids. Internally, the encoder mapping follows 8LV servo motor conventions to simplify controller parameter sets.

The motor cools by self-cooling, so enclosure airflow requirements are low and no auxiliary fan kit is needed. A battery-backed counter inside the encoder records up to 65536 revolutions, matching its multi-turn operating mode and eliminating the need for homing after power cycles. Because no holding brake is supplied, static loads must be secured by drive torque or external clamps.
