8LSA26R0045D100-0 by B & R Automation

The 8LSA26R0045D100-0 is a motor supplied by B & R Automation under the 8LS Synchronous Motors series. It is intended for industrial automation where precise velocity, torque, and position control are required, such as indexing tables, pick-and-place units, and coordinated conveyor axes. A permanent-magnet rotor lets the motor couple directly to a servo drive and respond quickly to command changes without mechanical gearing. In servo systems, this direct-drive response supports accurate interpolation on axes that change speed often and must settle quickly at the target position. This layout also supports compact axis design and helps keep motion behavior consistent during frequent starts, stops, and reversals.

Electrically, the machine uses a three-phase synchronous design, so commutation remains locked to rotor position for controlled torque across the speed range. Thermal management relies on self-cooling, which removes heat through the housing without an auxiliary blower when air can circulate around the frame. Power, feedback, and protective earth conductors are routed through a single industrial connector, reducing separate cable terminations at the motor. Using one connection point also helps keep the motor housing compact and simplifies cable routing where axis space is limited. The front face uses an IEC-compliant 58 mm square flange pattern, allowing straightforward attachment to compatible gearboxes, ball screws, or belt-drive assemblies.

The series code 8LSA identifies the motor platform used for this model, while length designation 6 marks the active lamination stack in this version. That length affects the body depth and the motor's continuous output capability, and it also helps distinguish this unit from shorter or longer members of the same range. Positioning accuracy is supported by the pilot surface on the integrated mounting flange, which helps the motor seat concentrically against precision gear stages or machine plates. Accurate centering at the flange reduces misalignment that can otherwise increase bearing load, vibration, and coupling wear in tightly toleranced drive trains. Open space around the housing should be maintained so normal surface heat can dissipate during operation.
