Users of factory automation units worldwide recognize B&R as a trustworthy supplier of innovative motion control products. The 8LS motors are three-phase synchronous motors by the company, built for high-performance operations. These motors are notable for their compact build that guarantees low weight and optical power density and precise encoder systems. Their typical application areas are seen in the plastics industry, metalworking industry, and beverage and food industry.
The 8LSA55.S0030D900-3 is an 8LS three-phase synchronous motor model designed by B&R. This permanent-magnet motor features electronic commutation and displays impressive controllability, thanks to its optimized torque rippling detail. It is a self-cooling motor with a built-in connector and slim, elongated construction. Its cooling is supported by its mounting flange, which acts as a cooling surface. It is also designed to be attached to machines by this flange. The encoder system present in this 8LS motor is the EnDat 2.2 optical encoder with a single-turn configuration. It detects the absolute, indirect position recording within one mechanical motor revolution and is optimized for functional safety. The nominal speed of the motor is 3,000 revolutions per minute.
Based on the design of the 8LSA55.S0030D900-3, its built-in connector is the angled type, and its encoder and power cable connections are separate. It is equipped with a standard holding brake and form A oil seal according to DIN 3760. This oil seal gives it an IP 65 Ingress Protection Rating, indicating that it cannot be penetrated by solid extrinsic materials or sprays from water jets. The motor’s holding brake is a permanent-magnet type and can be controlled by the B&R drive system with the 8LS motor.
