Product Description:

The 8LSA44.R0045D200-0 servo motor is produced by B&R Automation for the 8LS Synchronous Motors series. It is a three-phase rotary unit designed to supply controlled torque and speed in automated machinery when connected to a compatible drive. Within an industrial motion loop, the motor converts inverter output into mechanical energy for positioning axes, conveyors, or tool spindles. Its standard 8LSA design suits applications that do not require reinforced bearings.

This motor uses a three-phase synchronous design, so it maintains a constant rotor position relative to the stator field for precise speed regulation. Its rated speed is 4500 rpm, providing the continuous operating velocity needed for high-speed motion. Heat is removed through self-cooling, which relies on free air circulation around the housing and eliminates the need for external blowers. The square flange measures 100 mm, allowing direct attachment to gearboxes or machine plates drilled to the corresponding pattern. For stop-and-hold duties, an integrated standard holding brake secures the shaft when power is removed, helping protect vertical loads and maintain the axis position while the machine is stationary.

Feedback is supplied by a resolver, which provides sinusoidal position signals that compatible drives process for commutation and closed-loop control. Mechanical output is carried through a smooth shaft, facilitating the use of clamp or collet couplings when zero key backlash is desired. The device repeats motion commands with a positional accuracy of 10 arcmin, making it suitable for general-purpose indexing tasks. Cabling exits through an angled connection, and the mating electrical connector can be adjusted during installation while preserving the integrity of the connection. The motor has a length code 4 housing and does not include an oil seal, making it appropriate for applications without significant exposure to fluids.
