Product Description:
The 8LSA75.E3030D104-0 is a servo motor produced by B & R Automation for the 8LS Synchronous Motors series. The 8LSA designation identifies its motor family within the product type code. The motor supplies precise rotary motion to packaging, material-handling, and general factory automation axes that use electronically commutated drives. Its synchronous design supports controlled torque and speed when paired with a compatible servo drive.
This unit is built as a three-phase synchronous machine that reaches a rated speed of 3000 rpm, making it suitable for moderately high-speed positioning tasks. Mechanical durability is enhanced by a reinforced A-side bearing that supports demanding shaft loads. The stator housing has a flange measuring 190 mm across, allowing direct attachment to gearboxes or machine frames with a matching interface. Heat is removed through self-cooling with free air circulation, so no external blower or liquid cooling circuit is required. The motor is supplied without a holding brake, so applications that require static torque must rely on drive-applied torque or an external clamp. No oil seal is installed, and equipment exposed to lubricants or coolants should protect the shaft area from contamination. The cooling method also reduces the number of auxiliary components needed around the motor housing.
Cabling exits the housing through an angled connection that can swivel to improve routing and reduce strain on the cables. Power and feedback conductors terminate through a sealed connector set, allowing the cables to be attached or disconnected without opening the motor housing. The motor uses length code 5, which indicates the active core depth associated with its continuous torque capacity. A shaft with a key transmits torque securely to compatible couplings and helps prevent rotational slippage under load. The absence of an internal oil seal reduces shaft friction at higher operating speeds. The adjustable cable connection helps accommodate different installation orientations while maintaining orderly power and feedback routing.
