8LSA44.EB060D000-3 by B & R Automation

The 8LSA44.EB060D000-3 is a three-phase synchronous motor supplied by B & R Automation as part of the 8LS Synchronous Motors series. Within the series, it uses the 8LSA designation and is revision 3. The unit is intended for servo axes that require high positional accuracy, and it uses an inductive encoder with flange mounting for direct coupling to machinery. It does not include an integrated brake, so holding torque must be provided by the drive or by an external mechanism during standstill.

This model sustains a rated speed of 6000 rpm, allowing rapid cycle times in pick-and-place or spindle duties. The flange dimension is 100 mm, so the housing fits standard IEC-compatible mounting faces without additional adapters. Thermal management relies on self-cooling with free circulation, so no external blower or liquid circuit is required and heat is dissipated through the frame surface. Position feedback is generated by an inductive EnDat system, which provides digital communication to the drive and good immunity to electromagnetic interference. The resolution reaches 19/12 bits for single-turn and multi-turn data. Electrical terminations use a connector that mates directly to prefabricated motor cables, which supports straightforward cable attachment in enclosed spaces.

An EnDat version of 2.1 supports advanced monitoring functions, and the cable exit uses an angled swivel orientation for strain relief during axis motion. A smooth shaft accommodates backlash-free clamp couplings, while the encoder tracks up to 4096 revolutions in multi-turn operation without battery support. The absence of an oil seal reduces friction losses, and the motor uses a standard bearing set without reinforcement. Length code 4 indicates the active stack height, and the mounting flange has threaded holes to speed installation.
