Product Description:

The 8LCN58.EB030D030-0 synchronous motor is produced by B & R Automation for the 8LS Synchronous Motors series. Bearing the internal designation 8LSN, the unit is intended for general-purpose servo axes in automated assembly lines and material-handling stations. It attaches to machinery through a mounting flange, allowing rigid alignment with gearboxes or direct-drive load elements, while its smooth shaft simplifies coupling to precision clamping hubs.

At its nominal operating point, the rotor reaches 3000 rpm, a speed that fits common 1 kHz control loops without overspeed derating. The square 8LS frame provides a flange measuring 142 mm across, establishing the bolt circle used when selecting adapters. Rotor position is detected by an inductive EnDat encoder that supports bidirectional digital communication using version 2.1. This sensor delivers absolute feedback with a resolution of 19/12 bits for single-turn and multi-turn data, enabling drive controllers to command fine incremental moves without homing procedures. A length code of 8 indicates the overall stack height, balancing torque production against inertia.

The motor has multi-turn capability, and the encoder stores the shaft revolution count for up to 4096 revolutions, so position is maintained even after power loss. Power and feedback conductors exit the housing through an angled swivel connector, freeing space above the rear cover in tight installations. Thermal management relies on a self-cooling design with an increased mass moment of inertia, which dissipates heat through the frame and raises rotor inertia for smoother speed regulation. The motor has no holding brake, so static load retention must be handled externally. It also has no oil seal, meaning it should not be exposed to lubricants that could migrate along the shaft.
