8LSA43.E1030C600-0 by B & R Automation

The 8LSA43.E1030C600-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. It is intended for position and velocity control in industrial automation where compact servo axes are required. The motor follows the 8LSA configuration, meaning the standard housing is used and no reinforced bearing is fitted, which keeps mechanical compliance predictable for general-purpose drives.

This model operates at a rated speed of 3000 rpm, enabling direct coupling to moderate-inertia loads without gear reduction. Rotor position is monitored by an Optical EnDat encoder, and communication uses version 2.1, so absolute position is available at power-up with bidirectional diagnostics. A flange dimension of 100 mm permits interchange with other IEC-sized servomotors, while the stator uses self-cooling through free air circulation rather than external blowers or liquid jackets. Power and feedback lines exit straight upward through a top connector, and the single plug-in connector keeps cable routing compact. Because no holding brake is installed, the application must secure the load through drive torque or an external brake when power is removed.

Mechanical power is transmitted through a smooth shaft, which accommodates clamp or compression couplings. The integrated multi-turn encoder records up to 4096 multi-turn revolutions, preserving position reference over large travel ranges. Installation uses a mounting flange, matching the motor's length code 3 envelope for cabinets with limited depth. An oil seal is fitted at the shaft exit to help protect internal laminations from lubricant splash in gearboxes or linear stages. The standard 13/12-bit resolution supports precise interpolation in servo loops, and the design supports accurate feedback across the full speed range.
