Product Description:
The 8LSA75.EB022C104-0 is a three-phase synchronous motor manufactured by B&R Automation and assigned to the 8LS Synchronous Motors series. Within industrial automation, this unit provides rotary motion for axes that demand consistent speed control or precise positioning. Machine builders can couple it directly to ball screws, gearboxes, or belt transmissions through its keyed shaft. Its mechanical interface uses a 190 mm square flange that aligns with standard mounting surfaces and distributes radial forces evenly.
The motor uses a self-cooling design with free air circulation, so ambient airflow removes heat without external fans or liquid circuits. Under rated load, it reaches 2200 rpm, balancing dynamic response with torque production for general-purpose machinery. Rotor position is reported by an inductive EnDat feedback system. This contact-free method resists dust and oil films while maintaining high signal fidelity in industrial environments. Communication with the drive controller uses EnDat 2.1, enabling automatic parameter transfer and access to stored motor data during setup. The feedback arrangement gives the controller the position information needed to regulate speed, torque, and movement accurately throughout the operating cycle.
Cabling exits through a straight top-connector arrangement, keeping harness routing compact when the motor is installed in confined machine spaces or on moving carriages. The sensor provides a combined single-turn and multi-turn resolution of 19/12 bits, supporting precise velocity loops and absolute position recovery after a power loss. Internal counting extends across 4096 revolutions, eliminating the need for separate home switches on long-travel axes. A reinforced A-side bearing supports higher thrust loads when the shaft is coupled to belts or pinions. The motor has a length code 5 housing and a mounting flange interface. It is supplied without a holding brake or oil seal, so an external holding method may be necessary for loads that must remain stationary without motor torque. The keyed shaft end provides positive torque transmission to a compatible coupling, pulley, or gearbox input.
