Product Description:

The 8LSN44.R0030D100-0 is a three-phase synchronous motor produced by B & R Automation within the 8LS Synchronous Motors series. Bearing the internal 8LSN designation, this unit is intended for servo axes that require moderate rotor inertia and consistent velocity control. In automated machinery, it functions as the primary rotary actuator, converting regulated current from a drive amplifier into precise torque for positioning tooling, transporting materials, or synchronizing production cycles.

With a flange dimension of 100 mm, the motor uses the standard configuration and length code 4 for its overall stack length. Its nominal operating point is a rated speed of 3000 rpm, matching common drive outputs for packaging, handling, and assembly equipment. The stator relies on self-cooling, eliminating the need for an external fan, while the motor’s mass moment of inertia helps stabilize motion during load changes. Cabling leaves the housing through an angled swivel connector, which simplifies routing in confined machine spaces. Rotor position is monitored by a resolver, supplying noise-resistant analog feedback for closed-loop control. The motor does not have an oil seal, so additional protection is required where process liquids or fine particles could reach the shaft opening.

The unit includes a mounting flange that allows the housing to be bolted directly to a gearhead or machine plate. Torque is transferred through a keyed shaft end, providing positive engagement with a compatible coupling or driven component. Mechanical backlash is limited to 10 arcminutes, supporting repeatable load alignment during direction changes. The motor is supplied without a holding brake, so an external clamping device or drive-based braking function must maintain the position of a vertical load when power is removed. Applications exposed to fluids or airborne contaminants should provide suitable guarding around the unsealed shaft interface.
