Product Description:

The 8LSA44.R0030D300-0 is a three-phase synchronous motor produced by B&R Automation and supplied in the 8LS Synchronous Motors series. Designed as a drive axis for packaging lines, pick-and-place gantries, and similar motion tasks, the unit converts electrical energy into controlled rotary torque with high positioning accuracy. In factory cells, it pairs with compatible servo amplifiers to provide closed-loop speed and position control, allowing coordinated motion between multiple axes.

The motor carries the designation 8LSA, confirming the standard configuration that omits reinforced bearings and keeps weight moderate for gantry mounting. Its length code is 4, which corresponds to the active stack height, and thermal capacity is supported by the self-cooling principle that uses free air circulation instead of forced ventilation. During continuous operation, the rotor can reach 3000 rpm, and positional error is held within 10 arcmin, a value suitable for medium-precision indexing tables. A centering register of 100 mm on the front face simplifies alignment, while power and feedback leads exit through an angled swivel connector interface that reduces cable stress in enclosures. A molded connector body locks against vibration during high-acceleration cycles.

Motion feedback is supplied by a resolver, an analog transducer that maintains accuracy in high-temperature environments without complex electronics. For static load retention, the motor integrates a standard holding brake, eliminating the need for external clamping devices during power-off conditions. The output shaft is supplied with a key, allowing immediate coupling to pulleys or gearboxes; an oil seal is not present, so installations that expose the shaft to lubricants must use an external seal on the driven component. A factory-machined mounting flange lets the unit bolt directly to equipment frames.
