8LSA44.D0030D000-0 by B & R Automation

B & R Automation manufactures the 8LS Synchronous Motors series, and the 8LSA44.D0030D000-0 is one of its standard variants. This three-phase motor is built for precise rotary positioning and speed regulation in automated machinery. Integrated into servo axes, it can drive loads directly without mechanical reduction stages, improving response and accuracy in packaging, material handling, and assembly lines. That direct-drive approach can reduce backlash from extra transmission elements and helps the axis follow rapid command changes more smoothly. Its construction also suits repeated start-and-stop motion where consistent position control is important.

Beneath its housing, the motor uses a three-phase synchronous electromagnetic design that maintains constant torque across the speed range. The continuous rated velocity is 3000 rpm, so control systems can command rapid cycles while staying within thermal limits. Heat is removed through self-cooling with free circulation, eliminating the need for forced-air or liquid circuits. Mechanical attachment uses a 100 mm flange that matches IEC mounting patterns, and the power and feedback conductors exit through an interface in an angled swivel orientation to ease cable routing in tight cabinets. This layout helps preserve cabinet space around the motor connection area. A connector plug set is preinstalled, and the length code 4 stator keeps the motor body compact while supporting the listed torque class.

The feedback subsystem relies on an Optical EnDat sensor, and this resolver-free design follows version 2.2 of the protocol for bidirectional parameter transfer and startup data exchange. Position data are delivered with a 25-bit single-turn resolution, so the motor is suited for axes that return to a reference position at power-up rather than requiring multi-turn position retention. The encoder arrangement also gives the drive detailed position feedback for precise speed and motion control during normal operation. The rotor has a smooth shaft, so torque is transmitted with friction couplings or clamping hubs rather than keyways. No holding brake or oil seal is integrated, which reduces inertia and suits clean, dry environments where external holding methods are acceptable.
