Product Description:
The 8LSA57.E3045D200-0 belongs to the 8LS Synchronous Motors series produced by B&R Automation. It is a servo motor intended for position and speed control in packaging stations, pick-and-place axes, and similar motion applications where a compact torque source connects directly to a drive controller. Delivered in an 8LSA configuration without reinforced bearings, the unit uses the standard bearing arrangement for this motor type. Its housing supports installation in automated machinery that requires accurate rotary motion and stable closed-loop operation.
The power and feedback leads exit the housing through an angled swivel arrangement, and a keyed connector provides a secure electrical interface. Heat generated in the stator is removed through self-cooling with free air circulation. No external fan or liquid cooling circuit is required, which reduces the number of auxiliary cooling components around the motor. The front face has a 142 mm flange that supports accurate alignment with a compatible gearbox or machine frame. A standard holding brake is built into the motor for vertical or indexing axes. The brake engages when drive power is absent, helping prevent the connected load from moving during a power loss.
The motor has a nominal speed of 4500 rpm, allowing rapid motion cycles when it is paired with a compatible drive. Its smooth shaft accepts clamp-style or shrink-fit couplings that transmit torque without a keyway. The three-phase synchronous design provides controlled torque in response to drive current, supporting precise speed and position regulation. The motor uses length code 7 for its axial stack configuration. It does not have an oil seal, so it is best suited to installations where the shaft is not exposed to coolant, lubricant spray, or similar fluids. The flange-mounted housing keeps the motor rigidly positioned while the angled connection arrangement helps route cables away from nearby machine components.
