Product Description:

The 8LSA34.R0030D100-0 is a servo unit manufactured by B & R Automation and included in the 8LS Synchronous Motors series. This configuration is the standard build without reinforced bearings. It is engineered for industrial automation tasks that require compact, precisely regulated rotary motion, such as conveyor sections, pick-and-place axes, or general machine modules. When driven by a compatible inverter, the motor converts controlled three-phase power into mechanical rotation for closed-loop speed and position control across factory equipment.

The motor has a rated speed of 3000 rpm for its continuous operating point before thermal derating begins. The rotor follows a stator field generated by a three-phase synchronous winding set, which eliminates steady-state slip during normal operation. Position feedback is supplied by a resolver, providing analog sinusoidal signals that remain stable in electrically noisy environments. Heat from copper and iron losses is removed through self-cooling with free circulation, so no auxiliary blower or coolant loop is required at nominal load. Commanded moves can be repeated with an angular accuracy of 10 arcmin, which is suitable for many mid-range servo applications. This feedback arrangement supports consistent speed and position control while keeping the motor layout straightforward.

The mounting interface has a flange outer dimension of 91.3 mm, matching common frame patterns for direct bolting to machine plates. Cables exit through a connector with an angled swivel orientation, which helps routing in compact machine spaces. Load coupling is handled by a shaft end machined with a key, allowing positive torque transfer to sprockets or couplings. The motor has no holding brake, so vertical or suspended axes must rely on external braking hardware or maintained drive torque during power-off conditions. This layout supports compact installation where cable clearance and secure shaft coupling are both important.
