Product Description:
The 8KSJ95.E7020B100-0 launches as a three‑phase asynchronous motor design that enhances torque consistency. Manufactured by B & R Automation, this motor’s design voltage of 400 V basically matches common industrial power supplies which eliminates step‑down transformer needs. Its power output of 2.0 kW delivers mid‑level drive capability which accommodates a variety of machinery loads. A frequency rating of 50 Hz aligns with global grid standards which simplifies direct connection.
A nominal speed of 2850 rpm supports rapid cycle operations, thus maintains process throughput. A current draw of 4.1 A sustains continuous torque delivery to prevent thermal overload. An IP55 protection class repels dirt and low‑pressure water jets, preserving internal components and gives long lasting life. B3 foot mounting secures the device firmly to standard baseplates which prevents vibration‑induced misalignment. A frame size 90S provides a compact envelope and conserves installation space. An IE2 efficiency classification ensures lower energy consumption, thereby reducing running costs. This B & R’s variant 8KSJ95.E7020B100-0 holds installation up to 1000 m above sea level that can expand application in elevated facilities.
An IC411 cooling method circulates air within the enclosure to maintain thermal stability without extra blower. Model with insulation class F rating withstands coil temperatures up to 155°C, extending winding longevity. A built‑in thermistor offers over‑temperature protection and prevents insulation damage. A housing constructed from aluminum reduces overall mass which enhances heat dissipation. A motor weight of 54 kg simply lightens structural loads which simplifies support framework design. Further, a meantime between failures of 520 hours guides preventive maintenance scheduling and that improves uptime planning. 3‑phase asynchronous drives under 1000 V often survive up to 20 years which informs long‑term lifecycle management.
Frequently Asked Questions about 8KSJ95.E7020B100-0:
Q: In what way does rotational speed influence the 8KSJ95.E7020B100-0’s operation?
A: A nominal speed of 2850 rpm provides near‑synchronous motion which reduces slip losses and vibration, enhancing precision in position‑sensitive applications.
Q: How does the current rating benefit the 8KSJ95.E7020B100-0?
A: A rated current of 4.1A regulates electromagnetic torque generation which prevents drive overload, ensuring consistent performance during peak load cycles.
Q: What advantages does IP55 protection bring to the 8KSJ95.E7020B100-0?
A: IP55 rating prevents ingress of dust and water spray which protects internal components, reducing the risk of electrical faults and extending service intervals.
Q: How does the mounting arrangement affect the 8KSJ95.E7020B100-0?
A: A B3 (foot mounted) configuration provides a stable installation base which simplifies alignment and secures the motor against vibration on standard mounting surfaces.
Q: What does frame size 90S indicate for the 8KSJ95.E7020B100-0?
A: The frame size 90S adheres to IEC standards which maintain that the motor’s dimensions and mounting hole pattern match industry conventions for seamless replacement and integration.
