8LSA56.E2030C000-1 by B & R Automation

The 8LSA56.E2030C000-1 motor belongs to the 8LS Synchronous Motors series developed by B&R Automation. It is a rotary actuator intended for feed axes, pick-and-place heads, and similar motion stages where precise speed tracking and repeatable torque are required. By integrating directly with the manufacturer's servo drives, this unit helps automate positioning tasks without adding mechanical transmissions or external cooling accessories. Its design also suits compact motion systems that need quick starts, controlled stops, and steady repeatability during frequent cycling.

The motor's nominal operating velocity is 3000 rpm, giving the drive controller a stable operating point for closed-loop motion control. A flange face measuring 142 mm provides the mounting interface and keeps the stator housing centered accurately on machine plates. Heat is evacuated through a self-cooling design that relies on free air circulation around the housing, so no blower or liquid jacket is necessary. Power and feedback leads exit through a straight top connector, an orientation that keeps cables clear of adjacent axes and supports tidy routing inside compact enclosures. A smooth shaft is provided, allowing backlash-free coupling with clamping hubs or pulley bores while avoiding keyway stress points. Because the motor has neither an oil seal nor a holding brake, the driven machine must provide external sealing, and load holding during power loss must come from the control system or a separate mechanical device.

This is a three-phase synchronous motor, so torque is produced by sinusoidal currents matched to a permanent-magnet rotor, which helps reduce cogging and improve efficiency at light loads. The integral mounting flange carries the reaction forces generated during acceleration without the need for foot brackets. Its standard 8LSA configuration omits reinforced bearings, which reduces inertia and supports faster response in lightly loaded axes that reverse direction often. The assembly follows length code 6, indicating a moderate rotor stack that balances continuous torque output with compact overall dimensions.
