Product Description:

The 8LSA35.R0030D100-0 is a three-phase servo motor that B&R Automation supplies under its 8LS Synchronous Motors series. As a compact rotary actuator, the unit converts drive current into controlled torque for indexing tables, packaging axes, and material-handling stations that need repeatable motion. The motor uses a three-phase synchronous design based on the 8LSA configuration, with standard construction and no reinforced bearing. This configuration supports controlled acceleration and positioning when the motor is paired with a compatible servo drive.

A flange face measuring 91.3 mm provides the reference surface for positioning, and a mounting flange is predrilled so the housing aligns directly with machine frames. Power and feedback lines exit through an angled swivel connector arrangement that simplifies cable routing in confined installation spaces. The sealed connector helps protect the electrical contacts from contamination during industrial operation. The shaft end is machined with a key to transfer torque into pulleys or couplings without slipping. Length code 5 indicates the stack depth used to provide the required torque density. No holding brake is integrated, so static load retention must be provided by the drive or external mechanical components. The motor does not include an oil seal, so external protection is required when the shaft may be exposed to splashing fluids or lubricant.

Heat produced in the stator is removed by self-cooling with free circulation. This natural-convection method simplifies installation because no auxiliary fans or liquid-cooling lines are needed. Nominal operation is specified at 3000 rpm, providing a practical balance between speed and torque for general automation applications. Position feedback comes from a resolver, allowing analog angle detection that tolerates electrical noise and elevated temperatures. The device maintains motion accuracy within 10 arcmin, making it suitable for pick-and-place heads and moderate-precision gantries. The feedback signal allows the connected drive to monitor rotor position and correct motion as operating loads change. The 8LSA designation distinguishes this standard motor configuration from versions equipped with reinforced bearings.
