Product Description:
The 8LSA44.R0030D100-0 three-phase synchronous motor is produced by B & R Automation for the 8LS Synchronous Motors series. The device converts electrical energy into tightly regulated rotary motion for pick-and-place units, indexing tables, and other machine axes found in automated cells. Its feedback interface supports precise control of torque, speed, and rotor position when the motor is paired with a compatible drive. The compact design also allows the motor to fit within space-constrained industrial machinery.
Continuous operation is specified at a shaft speed of 3000 rpm, giving the actuator the responsiveness needed for rapid duty cycles. Heat is dissipated through a self-cooling housing with free air circulation, eliminating the need for external fans or liquid cooling loops. Rotor position is reported by a resolver, allowing the drive to determine the shaft angle and regulate motion accurately. Mechanical attachment follows an ISO pattern with a flange width of 100 mm. The power and feedback leads use an angled, swiveling connection direction that helps relieve cable stress and supports flexible routing around nearby machine components. Commanded moves maintain repeatability within 10 arcmin, supporting precise part placement, alignment, and indexing operations.
The motor has length code 4, which indicates a mid-length configuration that balances torque output with installation depth. A keyed shaft end transmits torque through positive engagement with a compatible coupling, pulley, or gearbox. The shaft assembly operates without an oil seal, reducing friction during high-speed operation. Electrical terminations use a rugged connector that secures the power and feedback wiring at the motor housing. Because the motor does not include a holding brake, an external locking device or drive-applied torque must hold the axis in place when power is removed. The standard, non-reinforced bearing arrangement keeps rotating mass low and supports responsive acceleration during repetitive machine cycles.
