Product Description:
The B & R Automation 8LSN44.EB030D900-0 is a three-phase motor characterized by low inertia and impressive torque density. It is designed with 5 pole pairs that deliver precise and stable rotational performance across a range of motion control applications. The motor's low inertia means it requires minimal torque to change speed. This results in swift acceleration and deceleration, enhancing system responsiveness and minimizing energy consumption during dynamic motion sequences.
The 8LSN44.EB030D900-0 operates continuously at a nominal velocity of 3000 rpm under rated load and voltage conditions. This makes it a good fit for high-speed automation environments, where rapid and repeatable motion is required. The motor’s shaft design is smooth with no keyed connection. This simplifies mechanical integration, allowing straightforward coupling with the driven component. This shaft type optimizes power delivery and ensures a smooth rotational profile with a high load capacity and low-noise operation. This unit features self-cooling, allowing it to manage internal temperatures naturally without additional components such as fans or liquid cooling jackets.
This motor comes with a versatile swivel connector for ease of installation into varying setups. Users can rotate the connector as needed to meet their cabling and layout requirements, making set up much simpler. The motor has a 30-minute thermal time constant, indicating excellent thermal insulation properties during continuous use. The motor takes 30 minutes to reach approximately 63% of its final temperature after a change in load, allowing it to absorb short-term overloads without quickly exceeding its thermal limits. This longer thermal response time helps maintain temperature stability, protecting internal components from thermal stress. This ensures the durability of the motor even in demanding operations with long duty cycles.
