Product Description:

The 8LMA45.DB022C100-0 is a brushless AC synchronous motor produced by B&R Automation within the 8LM Synchronous Motors series. As a servo-class unit, it converts electrical power into rotational motion for positioning and velocity control tasks in industrial automation lines. Its winding design, feedback compatibility, and phase alignment allow closed-loop operation with the manufacturer’s drives and PLCs. By delivering controlled torque across a moderate speed range, the motor supports axis integration in packaging machines, assembly stations, and material-handling cells.

Under rated conditions, the motor delivers 1175 W while turning at 2200 rpm, producing a nominal torque of 5.1 Nm at the shaft. This continuous output is supported by a nominal phase current of 2.4 A and a rotor with five pole pairs. Copper losses are governed by the winding resistance of 4.32 Ω, while reactive behavior is influenced by a stator inductance of 41 mH. The electrical dynamics are characterized by a 9.49 ms time constant, indicating how quickly current approaches its steady value after a voltage step. With a back-EMF gradient of 134.04 V per 1000 rpm, the motor can be matched to mid-voltage servo inverters without additional gear-ratio scaling.

Beyond its continuous rating, the motor can produce up to 27.4 Nm for rapid acceleration and can draw a peak line current of 19.29 A. At standstill, the motor can hold 6.7 Nm, and the stall winding demand is limited to 3.02 A to help protect the amplifier during overload conditions. The electromechanical gain remains predictable because each ampere adds 2.22 Nm/A to shaft torque. Thermal buildup is moderated by a 35 min constant that reflects the housing mass and surface area, permitting intermittent overload events without immediate overheating during indexing or start-stop duty cycles.
