Product Description:
The 8LVA33.R0021D100-0 is a three-phase synchronous servo motor produced by B&R Automation for the 8LVA Three Phase Synchronous Motors series. Designed for closed-loop motion axes, the unit translates drive current into controlled torque and speed so packaging machinery, pick-and-place gantries, and other automated stations can achieve repeatable positioning under varying loads. Its mechanical outline follows the 8LV Servo Motor product family, providing a consistent form factor for integration with compatible B&R drive systems. This format also supports orderly installation in multi-axis machinery where available mounting space and cable routing must be carefully managed.
At a nominal output speed of 2100 rpm, the rotor can sustain application duty cycles that require moderate velocity while remaining within the magnetic and thermal limits of the winding set. The housing relies on self-cooling, which allows convection through the frame fins to remove heat without an auxiliary blower. Electrical connections pass through a built-in double angular connector, and its swivel feature allows the cables to be oriented along either machine axis. Signal integrity is maintained by an interface with separate encoder and power connections, which physically divides high-current conductors from feedback wires. Position feedback comes from a resolver, providing the shaft angle needed by the drive for closed-loop speed and position control. Resolver feedback also remains suitable for industrial environments where electrical noise could interfere with more sensitive signal types.
Repeatable indexing is supported by an angular accuracy of 10 angular minutes, meeting midrange precision requirements for feeders, indexing mechanisms, or rotary tables. Output torque is transferred through a keyed shaft, preventing slip between the motor and its coupling during repeated start-and-stop cycles. The feedback element is identified as RE-15-1-J04, which corresponds to the resolver electrical characteristics and connector pinout required by the associated drive. The size 3 motor frame establishes the mounting hole pattern, flange diameter, and overall stator volume. This predictable footprint helps arrange multiple motors on a common baseplate while preserving adequate clearance around the housings. The mounting layout also provides practical access to the shaft coupling and the adjustable electrical connector during machine assembly.
