Product Description:
The 8LSA43.E1030C600-0 is a three-phase synchronous motor produced by B&R Automation as part of the 8LS Synchronous Motors series. Intended for positioning and speed-controlled axes, it converts electrical energy into continuous rotary motion for packaging equipment, material-handling stations, and other factory automation systems. Its synchronous operation supports controlled torque and repeatable movement when paired with a compatible servo drive. The motor can be used for applications that require accurate acceleration, steady rotation, and coordinated positioning under changing loads.
The motor reaches a nominal speed of 3000 rpm, matching common servo-drive ratings for medium-inertia loads. Within the 8LSA frame group, length code 3 indicates a longer active stack that provides more continuous torque than shorter bodies. Heat is removed by self-cooling with free air circulation, so no external fan or liquid manifold is required. The square frame has a flange dimension of 100 mm, allowing direct attachment to compatible gearboxes or machine plates. Rotor position is monitored by an optical EnDat sensor that uses interface version 2.1 and supplies 13-bit single-turn and 12-bit multi-turn position data for precise interpolation. A smooth shaft simplifies connection to hubs or clamping collars without the stress concentrations associated with keyways.
Power and feedback conductors exit through a straight top connector, keeping cable bends minimal in compact machine installations. The standard circular connection hardware provides a secure interface for the associated motor and feedback cables. The prescribed mounting flange arrangement aligns the motor concentrically with the driven element, while the standard bearing configuration omits reinforced bearings. An internal oil seal blocks lubricant migration toward the encoder cavity and helps preserve reliable optical scanning. Because the motor does not include a holding brake, static loads must be secured mechanically if drive power is lost. The encoder retains position information over a multi-turn range of 4,096 revolutions, allowing the control system to recover the recorded axis position after the power supply is restored.
