8LSA35.R0030D200-0 by B & R Automation

B & R Automation manufactures the 8LSA35.R0030D200-0 motor within the 8LS Synchronous Motors series. The unit is a three-phase synchronous motor intended to drive positioning tables, conveyors, and automated tooling where repeatable speed is required. Used with compatible servo drives, it converts electrical input into controlled torque for medium-inertia loads in assembly and material-handling cells. Its compact frame supports cabinet or machine-side installation without auxiliary cooling hardware, and resolver feedback lets the drive close the velocity and position loops during operation. This arrangement supports closed-loop positioning and speed control in compact automation stations where repeatable motion is important over frequent cycles.

The motor reaches a maximum speed of 3000 rpm, which suits applications that need steady operation across common servo speed ranges. Heat is removed through self-cooling airflow around the housing, so no fan or coolant circuit is required. The housing remains simple because cooling is handled by the motor surface rather than by an external attachment. A 91.3 mm square flange provides the mounting pattern for the motor. Cables exit through an angled swivel connector that can be rotated to clear panel edges and reduce bend stress. Rotor position is supplied by a resolver, whose analog signals tolerate high electromagnetic interference and still support precise commutation by the servo amplifier.

A standard holding brake keeps the axis fixed when power is off, which is useful on vertical or indexing stations. The smooth shaft simplifies coupling installation because there is no keyway to align. Code 8LSA indicates the standard motor version without reinforced bearings or an oil seal, which suits light radial loads. Accuracy is held within 10 arcmin, meeting the needs of feeders, small gantries, and carton erectors. That level of positioning accuracy fits transfer tasks, indexing movements, and other small-axis duties that depend on consistent motion. The motor also uses length code 5 and a mounting flange interface.
