Electric motor 0,55 kW, 880 rpm, 400 V, 1AL-80M2-6

Electric motor 1AL-80M2-6 for reliable power supply and smooth 6-pole operation

Electric motor 1AL-80M2-6 from VYBO Electric is designed for operations where stable start-up, smooth speed and trouble-free integration into a standard three-phase system are expected. The power of 0.55 kW, rated voltage of 230/400 V and △/Y connection make it a practical drive for technologies that need a balanced ratio between compact size and dependable operating performance. The rated current of 2.78 A at 230 V and 1.6 A at 400 V provides a good basis for the correct design of connection, protection and control elements. At a frequency of 50 Hz, the rated speed reaches 880 rpm, so this is a 6-pole motor with a calmer, more even running characteristic, suitable for equipment where stable motion is valued more than rapid dynamics.

Electrical properties and their practical significance

In technology, it is not only important that the motor operates, but also how it behaves during start-up and under normal load. The starting torque ratio of 2.1 helps the motor overcome initial resistance without uncertain start-up. The pull-out torque ratio of 1.9 supports stability when the load fluctuates and the mechanical load changes during the cycle. The starting current ratio of 4.7 is important for the electrical design of the entire system, especially with more frequent starting or when connected to more compact switchboards. The motor is suitable for DOL starting, for frequency-inverter control and for operation with a soft starter. This expands the range of use from simple fixed drives to applications where a gentler start or regulation of the operating rhythm is needed.

This design is practical, for example, in fans, extraction units, smaller pumps, conveyor belts, packaging machines, mixing equipment, sorting modules, dosing technologies, filtration assemblies, labelling lines and service mechanisms of production equipment. In these applications, it is crucial that the motor operates clearly, smoothly and without unnecessarily abrupt reactions.

Speed, load and operating character

The rated speed of 880 rpm defines the operating character of this model very clearly. It is a pace that suits technologies with an emphasis on even running, more precise feed or controlled mechanical behaviour. The motor is intended for a parabolic or linear load curve, so it is suitable for equipment with a steady resistance as well as for applications where the load changes according to the operating point. The rotor inertia of 0.0019 kg·m² supports a brisk response without unnecessary sluggishness. During start-up, stopping and control via an inverter, the motor therefore behaves predictably, which is important in technological units with a repeated cycle.

The operating modes S1, S2, S3 and S4-S9 give this model a wide range of applications. It can work in continuous operation as well as in intermittent cycles, depending on the character of the equipment. The service factor of 1.0 corresponds to a precisely defined and reliable working duty within the rated conditions.

Construction, protection and temperature resistance

The frame size of 80 mm provides a balanced solution for machines where compactness is required, but where a sufficiently robust mechanical construction is also needed. The IP55 protection helps protect the motor against dust and normal operating moisture, which is essential in an industrial environment. IC411 cooling supports a stable thermal regime during daily use. Insulation class F and temperature rise B provide a suitable reserve for long-term operation. The motor is designed for an ambient temperature of up to +65 °C and an altitude of up to 1000 m, so it performs well in standard as well as warmer operating conditions.

Noise level of 54 dB(A) and vibration of 2.8 mm/s with vibration severity class A support smooth mechanical running. This is often important in equipment where the motor operates together with more precise parts of the line or where a calmer operating profile is monitored. The 1AL OPTIMAL series is built as a professional VYBO Electric platform for wide industrial use, with an aluminium frame, proven quality and quick commissioning.

Mechanical design and mounting details

On both the DE and NDE sides, 6204-2Z bearings are used, which contribute to stable rotor support and reliable operation under regular load. No. 2 lithium-based grease is suitable for normal industrial conditions. Balancing with a half key supports correct coupling with the mechanical elements of the equipment. The design includes 2-M20X1.5 cable glands, which makes clean power supply entry easier. The motor can rotate in either direction, so the motor can be easily adapted to the design of a specific machine or line.

The packaged weight of 11 kg and packaging dimensions of 320 × 220 × 260 mm are practical for logistics, handling and preparation for installation. The power factor of 0.72 and efficiency of 65% help with more precise technical design of the equipment and with planning operating conditions.

Practical drive for everyday industrial operation

Electric motor 1AL-80M2-6 is suitable wherever the technology is meant to operate calmly, reliably and without unnecessary complications in connection or control. It combines 0.55 kW output, 6-pole design, IP55 protection and flexibility in both starting and regulation. For production, building services equipment and various industrial mechanisms, it represents a stable solution that is easy to integrate into operation and maintains a balanced working character over the long term.
