Product Description:
B & R Automation a company known for automation solutions designs and manufactures the 8LSA74.E0022D600-0 8LS Synchronous Motor. This motor includes an EnDat single-turn encoder system with 512 lines (ECN1313). The motor is built in size 7 and features an exceptionally large motor length. It operates at a nominal speed of 2200 min-1 and delivers a nominal torque of 27.5 Nm.
The 8LSA74.E0022D600-0 8LS Synchronous Motor motor provides a nominal power output of 6336 W. It draws an operating current of 12.39 A during regular operation. The motor has a moment of inertia of 60 kgxcm^2 and includes a smooth shaft end. It does not feature a holding brake and uses a self-cooling system. The insulation class of the motor is defined under IEC 60034 as Class F. The motor includes thermal protection following IEC 60034-11 standards with a maximum winding temperature of 145 degrees C. It supports a maximum installation altitude of 2000 m above sea level. When the environmental temperature exceeds 40 degrees C the rated current and stall current are reduced by 10 % per 10 degrees C. The 8LS Synchronous Motors can operate reliably in ambient temperatures from -15 degrees C to +40 degrees C. However, the motor can handle up to +55 degrees C maximum during operation. The relative humidity during operation is specified from 5 to 95%, non-condensing. For safe storage, the temperature range is -20 to +60 degrees C.
The 8LSA74.E0022D600-0 8LS Synchronous Motor has a five-pole design which ensures stable and consistent performance. The motor complies with vibration severity R according to IEC 60034-14. The cross-section of the motor cable is 1.5 mm^2. It includes an oil seal for protection against contaminants. All components are optimized to support high-efficiency industrial motion tasks.
Frequently Asked Questions about 8LSA74.E0022D600-0:
Q: What protection is offered by IEC 60034-11 thermal monitoring in the 8LSA74.E0022D600-0?
A: The IEC 60034-11 compliant thermal protection prevents winding temperatures from exceeding 145 degrees C. This helps avoid thermal overloads during continuous duty cycles.
Q: How does the absence of a holding brake affect the 8LSA74.E0022D600-0 motor's use?
A: Without a holding brake, the motor is suited for dynamic applications that don't require stationary torque hold. This also reduces overall motor size and inertia.
Q: Why is a self-cooling system crucial for the 8LSA74.E0022D600-0 8LS Synchronous Motor?
A: The self-cooling system efficiently dissipates internal heat during high-load operation. This maintains operational stability without external cooling accessories.
Q: What is the benefit of having a smooth shaft end on the 8LSA74.E0022D600-0?
A: The smooth shaft end allows for versatile coupling options. It helps in reducing mechanical wear and vibration during start-stop cycles.
Q: How does Class F insulation in the 8LSA74.E0022D600-0 improve thermal durability?
A: The Class F insulation allows the motor windings to tolerate higher thermal loads. This extends service life in applications with frequent temperature fluctuations.
