Product Description:
The 8LSA55.R2030D000-3 is a three-phase synchronous motor manufactured by B & R Automation as part of the 8LS Synchronous Motors series. It converts three-phase electrical power into rotary motion that can be precisely regulated by a compatible drive, making it suitable for indexing tables, packaging axes, and material-handling gantries. The motor belongs to the standard 8LSA configuration group and is intended for direct integration into servo systems that require compact dimensions and reliable position feedback. Its synchronous design supports coordinated motion by maintaining a consistent relationship between the commanded electrical frequency and rotor speed.
The motor has a standard frame without a reinforced bearing, and its length code 5 active stack provides a balance between rotor inertia and continuous torque. A mounting flange with a diameter of 142 mm provides the mechanical interface for attachment to gearboxes or machine plates. The motor uses an angled swivel connection, allowing the power and feedback cables to be routed parallel to the housing when installation space is limited. Electrical termination is provided through a single multipin connector, which simplifies cable attachment and disconnection. Heat is dissipated through self-cooling with free air circulation, allowing the housing ribs to release thermal energy without an auxiliary fan. Under nominal operating conditions, the rotor reaches 3000 rpm and provides smooth rotary output through its three-phase winding arrangement.
The position loop is closed by a resolver that supplies rotor-angle feedback to the connected servo drive. Its mechanical precision is 6 arcmin, supporting accurate position monitoring during controlled motion. Torque is transmitted through a smooth shaft, which allows the motor to connect to a clamping coupling without using a keyway. The motor does not include a holding brake, so an external locking device may be necessary when a back-driven load must remain stationary after power is removed. It is also supplied without an oil seal, requiring appropriate external protection when the shaft is exposed to lubricants, dust, moisture, or other contaminants. The motor is produced as Product Revision 3, indicating the applicable revision level for this model.
