Product Description:

The 8LSA44.DA030D100-3 is a three-phase synchronous motor produced by B & R Automation for the 8LS Synchronous Motors series. This third product revision uses the 8LSA configuration, meaning a standard housing without reinforced bearings, and it carries length code 4 for its stator package. In automated assembly cells and packaging lines, the unit supplies regulated torque and speed to position tables, feed axes, and light conveyors, integrating easily with servo drives that accept EnDat feedback. Because it is a synchronous servo motor, it is suited to applications that require repeatable motion and stable speed control during frequent starts, stops, and short indexing moves.

The motor achieves a rated speed of 3000 rpm, so it can be direct-coupled to mechanisms that need medium rotational velocity without external gearing. A flange dimension of 100 mm sets the mounting interface, supporting compatibility with IEC motor frames already used on existing equipment. Rotor position is measured by an Inductive EnDat encoder that communicates with drive electronics over protocol version 2.2; this absolute sensor provides 19-bit single-turn resolution, eliminating the need for Hall switches or index pulses. Heat is removed through self-cooling with free air circulation, allowing the motor to run in cabinets where forced ventilation is not available.

Cabling enters through an angled swivel connector, and power plus feedback conductors are grouped in a single keyed connector to reduce wiring errors during installation and keep the rear connection area compact. The housing includes a mounting flange, so no foot brackets are required, and the motor has no holding brake, so vertical axes must rely on external clamps or drive torque for static holding. An oil seal is also omitted, which makes the unit better suited to clean, dry machine areas than to wet or oily zones. The shaft uses a keyed end for positive torque transfer when it is coupled to driven equipment.
