Product Description:
B and R Automation manufactures the 8LSE85.E1020D000-3 Synchronous Motor a high-performance motor designed for precise and reliable industrial motion control systems. It delivers a rated output torque of 103.7 Nm for continuous duty cycles. The peak holding torque (stall) of 123.4 Nm provides enhanced load resistance which makes it suitable for demanding automation applications that require stable torque and consistent mechanical performance.
For steady performance in high-cycle activities, the 8LSE85.E1020D000-3 Synchronous Motor maintains a constant operating speed of 2000 RPM. It runs on a nominal supply voltage of 400 VAC in a three-phase system. The motor draws 42.3 A under active load and handles peak current draw of 50.4 A during stall. The cooling is managed through a liquid cooling system with a water flow rate of 5 L/min. The thermal insulation is rated Class F which provides heat resistance in demanding applications. It has an IP64 ingress protection rating which makes it dust-tight and splash-resistant. The ambient temperature range for the motor's efficient operation is 0°C to +40°C. It is non-condensing and can withstand up to 80% relative humidity for safe internal functioning. For reliable use in a variety of settings, the maximum installation elevation is 1000 meters above sea level.
The 8LSE85.E1020D000-3 Synchronous Motor has an electrical interface that is equipped with a top-mounted power connector for simplified access. It features a flange-type mounting style for secure mechanical integration. The unit is designed without a dynamic braking system or holding brake. The product combines precision, thermal safety and environmental protection. The 8LS Synchronous Motors series ensures consistent output with controlled energy use. Each specification supports industrial requirements for reliability, installation ease and thermal stability.
Frequently Asked Questions about 8LSE85.E1020D000-3:
Q: What role does relative humidity tolerance play in motor integrity?
A: The 80% non-condensing humidity tolerance protects windings and bearings. It allows 8LSE85.E1020D000-3 to operate reliably in moist or semi-conditioned environments.
Q: How does 2000 RPM base speed support industrial control systems?
A: The base speed offers reliable operation in repetitive cycles. It supports high-speed indexing and load positioning with reduced wear.
Q: How does the Class F thermal insulation improve motor performance?
A: The Class F insulation in the 8LSE85.E1020D000-3 allows the motor to withstand higher internal temperatures. This extends lifespan in thermally demanding automation environments.
Q: Why is the liquid cooling system set at 5 L/min?
A: The 5 L/min water flow ensures rapid heat dissipation during high-load operation. This prevents thermal derating and stabilizes torque output under stress.
Q: What’s the advantage of a top-mounted power connector in 8LSE85.E1020D000-3?
A: The top-mounted connector simplifies cable routing in confined panels. It also minimizes interference with mounting structures.
