Product Description:

B&R Automation’s 8LSA44.E3030D100-0 belongs to the 8LS Synchronous Motors series and serves as a three-phase synchronous drive element for motion axes that require accurate speed and torque regulation. The 8LSA configuration indicates a standard build without reinforced bearings, and the motor integrates into machines through its mounting flange. In automated packaging, material handling, and robotics, the unit converts inverter output into controlled rotation so position loops and process cycles stay synchronized.

Its thermal and electrical ratings support continuous operation. A self-cooling, free-circulation housing removes heat without external airflow, supporting a nominal shaft output of 1451 W at the rated speed of 3000 rpm. At this operating point, the motor delivers 4.62 Nm while drawing a nominal phase current of 2.8 A through 3.6 Ω stator windings. During rapid acceleration or transient load changes, torque can rise to 22.8 Nm, and current can increase to 21.9 A. The five pole-pair rotor works with a torque constant of 1.63 Nm/A to maintain sinusoidal back-EMF. Electrical connections are angled through a swivel connector, simplifying cable routing, and the keyed shaft transmits motion directly. The length code 4 stator stack and the 100 mm flange dimension keep inertia moderate while fitting common mounting patterns.

During standstill, the motor sustains 6 Nm of torque while drawing only 3.7 A, so the drive can maintain position without overheating. Because a holding brake is omitted, mechanical locking must come from the application side. The absence of an oil seal decreases drag and reduces resistance at the shaft. For field-oriented control, the drive relies on the voltage constant of 98.44 V/1000 rpm to translate measured back-EMF into speed data, keeping the five pole-pair rotor synchronized throughout velocity ramps.
