Product Description:
The 8LVA33.R0015D100-0 is a three-phase synchronous motor produced by B&R Automation for the 8LVA Three Phase Synchronous Motors series. As a servo drive element, it converts pulsed inverter output into accurate rotary motion for pick-and-place arms, indexing tables, and conveyor sections. The design follows the 8LV servo architecture and pairs with standard B&R controllers to deliver consistent torque in compact machinery where panel space and wiring access are limited. Its synchronous operation supports controlled acceleration and precise speed regulation when connected to a compatible inverter.
Its nominal speed of 1500 rpm establishes the rated operating point for steady-state duty, while feedback accuracy of 10 angular minutes supports repeatable positioning cycles under closed-loop control. The frame is classified as size 3, which sets the flange pattern and shaft diameter used across midrange axes in the platform. A self-cooling housing dissipates heat by natural convection, eliminating the need for an auxiliary blower. Cabling exits through a built-in double angular connector that can swivel, allowing power and signal bundles to run parallel to machine panels without sharp bends. Motor length code 3 keeps the housing compact for installations with limited axial space. The motor has no holding brake, so external clamping is required when back-driving forces could move a stationary axis. It also has no oil seal, making additional protection necessary where fluids could reach the shaft opening.
An interface with separated encoder and power connections isolates power conductors from sensor wiring, minimizing electromagnetic interference on feedback lines. Position data is generated by the RE-15-1-J04 resolver, which supplies analog sine-cosine signals to the drive for rotor position monitoring. This feedback allows the controller to regulate commutation and respond to changes in commanded position or speed. A keyed shaft couples output torque securely to pulleys or gearboxes without relying on friction alone. The positive mechanical engagement helps prevent coupling slip during repeated acceleration and deceleration cycles.
