Product Description:
B&R Automation manufactures the 8LWA23.B8030S100-0 as part of the 8LWA High Torque Servo Motors series. This high-torque servo motor converts drive current into tightly controlled rotary output for positioning axes, indexing tables, and pick-and-place heads in automated equipment. The model has motor size 2 and length code 3, providing a compact envelope while supporting the elevated torque density associated with the platform. Its rotary output allows compatible motion controllers to regulate position, velocity, and torque in closed-loop automation systems.
The electrical interface uses a single-cable connection that combines power, encoder, and fieldbus lines, and the connector is mounted on an angled swivel so cable routing can follow the machine frame. Thermal loads are managed by a self-cooling housing, maintaining performance at the nominal speed of 3000 rpm without auxiliary fans. The IP64 protection rating protects internal components against dust and water spray. Position data come from an EnDat 2.2 absolute encoder that provides a single-turn resolution of 19/0 bits and an accuracy of ±120 arcminutes. The encoder reports absolute position within one mechanical revolution but does not retain travel across multiple turns. This motor is supplied without a holding brake, so an external mechanism or drive-applied torque must secure a stationary load when necessary. It also lacks an oil seal, which reduces shaft friction but requires the coupling area to remain protected from lubricants and contaminants.
Thermal protection is provided by an embedded AM-LPTC1000F temperature sensor, enabling the drive to reduce current before the motor reaches its insulation temperature limits. The motor tolerates operational shocks of up to 2000 m/s², making it suitable for equipment that experiences rapid acceleration or impact loading. Output torque is transferred through a keyed shaft interface, ensuring secure engagement with compatible gears, pulleys, or rigid couplings. The angled connector position also helps prevent excessive cable strain where installation space is limited. Applications that require absolute position tracking across multiple revolutions must establish an external reference after startup.
