8LSA43.R0030D000-0 by B & R Automation

B & R Automation builds the 8LSA43.R0030D000-0 within its 8LS Synchronous Motors series. This three-phase synchronous unit is intended to drive positioning axes and speed-controlled spindles in automated assembly lines, where closed-loop control and compact installation are priorities. In automated machinery, it converts electrical input into controlled rotary motion for indexing tables, feed axes, and other servo-driven mechanisms. The motor is suited for applications that need accurate positioning and steady speed response without a large housing footprint.

The motor delivers a rated speed of 3000 rpm, so it can maintain that rotational speed while producing nominal torque. Heat is removed through self-cooling with free air circulation, which eliminates the need for an external blower or liquid circuit. Rotor position feedback comes from a resolver encoder, and that signal gives the drive continuous rotor-angle information for commutation and speed regulation. Motion repeatability is held to 10 arcmin, which helps limit positioning error in coordinated multi-axis systems. Because there is no holding brake, the load must be secured by the machine or held electrically when power is removed. The motor uses a 100 mm flange for mounting to compatible machine interfaces.

The angled connection header helps route cables in tight cabinets, and the molded connector mates with standard hybrid leads for power and feedback. This layout helps keep cable bends manageable near the motor body and supports orderly routing in compact equipment. A smooth shaft works with clamp or shrink-fit hubs, while the mounting flange supports secure attachment to compatible machine plates. Overall body length follows length code 3, which keeps the housing size consistent within this variant. The 8LSA configuration uses standard bearings, and the lack of an oil seal is intended for clean, dry environments where contaminants and external lubricant are not expected.
