Product Description:

The 8LSA35.DA030S200-3 is a three-phase synchronous motor manufactured by B & R Automation for the 8LS Synchronous Motors series. Within the internal 8LSA designation, this model is the standard build without reinforced bearings and is intended for axes that require accurate velocity and position control in automated assembly and packaging lines. It connects directly to compatible servo drives and converts commanded current into rotary motion for moderate-inertia loads. The synchronous design supports controlled acceleration, steady rotation, and repeatable positioning when paired with a suitable feedback-compatible drive.

The motor delivers a rated speed of 3000 rpm, establishing the continuous operating limit for the shaft. Heat is removed through self-cooling with free air circulation, which keeps the frame within its temperature limits when sufficient ambient airflow is available. Power, feedback, and brake conductors share a single-cable hybrid solution routed through a keyed connector, reducing wiring complexity and the number of separate cable runs. Mechanical mounting is handled by a square flange with an outer dimension of 91.3 mm, allowing the motor to fit many compact gearbox and machine interfaces. Position feedback is supplied by an inductive EnDat encoder that communicates with compatible drives using EnDat 2.2. Its 19/0 single-turn and multi-turn resolution supports fine interpolation while retaining single-turn position capability. The length code 5 stator stack balances torque output against overall motor mass, while the standard connector interface provides a secure connection for the combined cable.

A standard holding brake locks the rotor when power is removed to prevent drift on vertical or indexed axes. Torque is transmitted through a smooth shaft, eliminating keyway stress when a clamping coupling is used. Installation relies on the provided mounting flange, which supports rigid attachment and accurate alignment with the driven equipment. Because the motor has no oil seal, the host machine must prevent oil and other external contaminants from reaching the shaft opening. The standard bearing arrangement is suited to applications that do not impose unusually high radial forces on the shaft. Product revision 3 identifies this release within the 8LSA family, and the integral keyed connector maintains proper cable orientation during installation. The combined connection also keeps power, feedback, and brake wiring within a compact routing path around the motor housing.
