Product Description:
The SK45B21140-000 by Pacific Scientific is a permanent magnet AC servo motor for industrial automation. This motor delivers 1.55 kW of continuous rated power as its main operational parameter. The motor functions under a rated operating condition that combines 330 V voltage with 6.7 A current. The servo motor maintains a constant speed operation at 2000 rpm during full load conditions.
The SK45B21140-000 servo motor operates within insulation category F, where it displays strong resistance to high temperatures. The motor reaches its maximum torque performance of 29.5 Nm when used under intermittent duty type S3 to deliver powerful acceleration. The unit reaches the maximum current output of 30.5 A for brief durations. Position feedback and speed control operations of this motor depend on a resolver sensor. Industrial harsh conditions do not affect its technical performance. Rugged precision is the hallmark feature of single-speed (1X-RX) resolvers, which serve as the feedback type. The braking system of SK45B21140-000 servo motor utilizes 10 Nm torque through a 24 V holding brake for its operation. The 0.65 A current used by the brake enables secure position retention before shutdown. The motor housing meets the IP64 standard, which ensures it stays dust-proof along with withstanding water spray. The product functions well in moisture environments reaching 95% non-condensing humidity levels that suit industrial ground surfaces.
The ambient operating temperature for this SK45B21140-000 servo motor falls within the 0°C to 40°C range. Altitude rating is up to 1000 meters above sea level without derating. The shaft equipment features a keyed-type structure combined with a pulley mounting system. The electrical winding system of this component delivers steady torque at different operational loads. It achieves the IEC 60068-2-6 standard vibration resistance performance at 2g peak magnitude.
