Product Description:

The 8LSA26.R0045D000-0 is an AC servo motor built by B&R Automation and part of the 8LS Synchronous Motors series. It carries the 8LSA designation and follows a standard configuration without reinforced bearing elements, keeping mass and inertia moderate for general-purpose axes. In automated assembly stations, packaging machines, and material-handling modules, the unit supplies closed-loop rotary motion wherever precise electrical actuation is required.

The motor achieves a rated speed of 4500 rpm, allowing fast cycle execution while staying within the continuous torque envelope. Its flange face measures 58 mm, so it fits compact gearbox or direct-drive layouts that follow common IEC sizing patterns. Feedback is produced by a resolver, which tolerates temperature and vibration well and delivers position data to the drive controller. Power and feedback lines exit through an angled swivel connection that saves cabinet depth and helps prevent sharp cable bends, and termination is completed with a sealed connector housing. Mechanical integration is handled by a mounting flange, and thermal control relies on self-cooling through free air circulation, eliminating the need for external blowers or liquid jackets.

The 8LSA construction uses a three-phase synchronous design, so torque is generated through permanent-magnet interaction without rotor slip. Positional repeatability is held within 10 arcmin, which suits indexing tables and moderate-precision pick-and-place heads. A smooth shaft eases coupling to friction hubs or clamp collars, and the motor uses length code 6 for the active stack height in this power class. No holding brake is fitted, so static load retention must be provided by the drive or external mechanical locks, and the absence of an oil seal suits dry-room installations where lubricant containment is unnecessary.
