Electric motor 1AL-71M2-2 0.55 kW for compact drives with confidence in everyday operation
Electric motor 1AL-71M2-2 from VYBO Electric is a practical solution for industrial equipment where a higher working rhythm, space-saving design and reliable operation throughout the entire shift are required. It is a three-phase asynchronous electric motor with an output of 0.55 kW, a 2-pole design and rated speed of 2790 rpm at a frequency of 50 Hz. The rated voltage of 230/400 V and connection Delta/Star allow easy integration into standard three-phase systems, which makes it easier to design new equipment and modernise existing technology.
The 71 frame size gives this model a very good basis for machines where compact dimensions need to be combined with regular and stable working performance. The power level of 0.55 kW is particularly interesting in operations where the motor already plays a visibly important role in the process, yet a space-saving solution is still expected without unnecessarily large installation dimensions. In such situations, reliable starting, smooth operation and good readiness for repeated operation are decisive.
When technology needs a brisk drive without unnecessary downtime
The 1AL-71M2-2 model achieves a power factor of 0.82 and an efficiency of 74 %. Rated current is 2.26 A at 230 V and 1.30 A at 400 V, which provides a reliable basis for proper electrical sizing. In practice, for this power class it is equally important how the motor behaves during start-up and when the working load changes. A starting torque ratio of 2.3, a breakdown torque ratio of 2.3 and a starting current ratio of 6.1 describe a motor that is ready to handle regular starts with confidence and stable performance.
Such properties are important wherever the drive does not operate in just one monotonous mode. In many devices, start-up, steady running and changes in resistance alternate depending on the specific production operation. If the technology is to run smoothly, the motor must respond predictably and without unnecessary load on the entire system. That is precisely where the practical value of this model lies.
Prepared for the rhythm of modern production
1AL-71M2-2 is suitable for operating modes S1, S2, S3 and S4-S9. This means that it has a place in continuous operation as well as in processes with intermittent or cyclic loading. The service factor 1.0 corresponds to rated operating conditions and the parabolic or linear load characteristic extends the range of applications in various technologies where the nature of the load changes during the working cycle.
In real operation, this is very important for mechanisms that convey, dose, extract, ventilate or mix. A smaller and medium-light drive often determines whether the entire line will run calmly and without unplanned stoppages. A motor in this class therefore must handle not only the actual running, but also regular start-up without nervous behaviour.
Durability you can feel in everyday use
The motor is designed in an aluminium frame and operates with IP55 protection, which guards against dust and splashing water. In workshops, production halls and technical rooms this is a very important feature, because the drive is better prepared for the everyday industrial environment. IC411 cooling supports a stable thermal regime during longer operation. Insulation class F and temperature rise B complete the technical basis suitable for regular and long-term operation.
The running quality is supported by a vibration velocity of 2.8 mm/s in class A and noise level of 64 dB(A). This is especially welcome in equipment that operates in more compact production units or stands closer to the operator. The motor can rotate in either direction, which broadens the range of use in universal mechanisms and in assemblies with reversal. Balancing is carried out with a half key. On both the DE and NDE sides, bearings 6202-2Z are used and lubrication is provided by No. 2 lithium-based grease.
Natural application in a wide range of technologies
The power of 0.55 kW and speed of 2790 rpm make this model a suitable drive for equipment where a brisk mechanical response and reliable working rhythm are required. It is well suited to conveyors, material feeders, packaging assemblies, labelling units, sorting modules and dosing stations. It also has its place in fan assemblies, extraction systems, pumping modules, mixers with light to medium-light load, filling workplaces, assembly lines, service equipment and auxiliary production mechanisms.
The main benefit is that the motor can fit well into equipment where space is limited, yet operation already requires a noticeably higher working output than the smallest drives. As a result, it is a sensible choice for technologies that need a reliable everyday drive without unnecessary compromises in size and durability.
Advantages of the 1AL OPTIMAL platform where they make sense
The model belongs to the 1AL OPTIMAL range, which is popular among customers thanks to its excellent value for money, proven quality and broad usability across various industries. The platform is available in mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34, which widens the options for installation into different types of machines and equipment. Its strengths also include compatible feet, the option of replacing the front cover, a reinforced terminal box, improved IP55 terminal box protection, a steel fan cover, a carefully designed frame to improve cooling efficiency and reinforced bearings.
The motor is fitted with cable glands 2-M20X1.5. Packaging dimensions of 260 × 170 × 215 mm, packaging weight of 6.3 kg and rotor inertia of 0.0009 kg·m² complete the technical picture of handling, logistics and mechanical behaviour. The motor is suitable for DOL starting and, depending on the needs of the technology, also for control by a frequency inverter or soft starter.
Electric motor 1AL-71M2-2 is therefore a strong choice for compact industrial drives that need fast operation, durable construction and confidence in regular operation in a modern working environment.
