When a compact drive is already carrying a noticeable working load
Electric motor 1AL-80M2-4 from the 1AL OPTIMAL series belongs to a power class in which more is expected from the drive than basic operation alone. With an output of 0.75 kW, rated voltage of 230/400 V and connection Delta/Y, it is ready for technologies where operation must be stable, installation reasonably space-saving and motor behaviour clearly readable throughout the entire shift. At a frequency of 50 Hz it reaches rated speed of 1390 rpm and operates in a 4-pole design. The 80 mm frame, that is, the shaft height of 80 mm, provides a solid base for machines that already transfer more noticeable mechanical load, while still maintaining a compact design solution.
This model is a natural fit for belt conveyors, packaging lines, filling equipment, sorting modules, labelling systems, mixing sets, fan units, pump units, dosing mechanisms, feed technologies, material handling equipment and various automated workstations. In these applications it is often crucial that the motor handles a regular working rhythm without an unnecessarily restless character and can be easily integrated into both existing and new technology.
A reliable start and a smooth running cycle are important
In equipment with frequent starts or a repeated working step, the motor’s behaviour during run-up is very important. The 1AL-80M2-4 model operates with a rated current of 3.22 A at 230 V and 1.85 A at 400 V. The ratio of starting torque reaches 2.3, the ratio of breakdown torque 2.3 and the ratio of starting current 6. In practice, this helps in technologies where the drive is expected to provide a predictable start, stable engagement and reliable behaviour even during regular starting in production.
An efficiency of 73 % and a power factor of 0.76 support balanced operation under longer load. The motor is intended for a load type with a parabolic or linear load characteristic, so it is well suited to mechanisms with varying resistance, medium flow and material movement. Important too is the rotor moment of inertia of 0.0021 kg·m². In equipment where the working step is repeated at regular intervals, this helps maintain good drive response and smoother behaviour of the whole assembly.
Operation in a production environment places clear demands on the motor
A drive in industry must operate reliably even in environments where dust, higher temperatures or regular mechanical stress occur. That is why the IP55 protection rating is important, helping to protect the internal parts of the motor from dust and splashing water. In packaging machines, conveyor modules, mixing equipment or material handling technologies, this is a practical advantage that supports long-term operational reliability. Thermal stability is provided by IC411 cooling, while the frame of the 1AL OPTIMAL series is designed for effective heat dissipation.
The motor uses insulation class F and temperature rise B. It is designed for an ambient temperature of up to +65 °C and for altitudes up to 1000 m. The service factor of 1.0 together with operating modes S1, S2, S3, S4-S9 broadens the range of applications from continuous operation to intermittent sequences. Noise level of 58 dB(A) and vibration of 2.8 mm/s in class A help maintain a refined mechanical character, which is important in machines where stability, precision and overall working comfort in the hall are monitored.
Mechanical design and control without unnecessary restrictions
Both the DE and NDE ends are fitted with 6204-2Z bearings. Lubrication is provided by No. 2 lithium-based grease in the appropriate temperature class. Balance with a half key supports even running when fitting pulleys, couplings and other power transmission elements. The motor is suitable for DOL starting and also supports control via a frequency inverter and a soft starter. This allows it to be adapted to simpler applications as well as technologies requiring gentler run-up or better starting control.
The motor can rotate in either direction, which expands its use in reversing mechanisms, bi-directional feeds and equipment with a changing direction of working movement. For electrical connection, 2-M20X1.5 cable glands are provided. The logistics aspect is practical too. Packing weight is 11 kg and packaging dimensions are 320 × 220 × 260 mm, so handling during installation, storage and service replacement remains simple.
1AL OPTIMAL as a proven platform for industry
The 1AL OPTIMAL series is one of VYBO Electric’s best-selling ranges, with more than 30,000 units installed in industry. 1AL OPTIMAL is among the best-selling electric motors from VYBO Electric and has more than 30,000 installed units in industry. The series is known for very good value for money, proven quality, high compatibility and fast commissioning. Practical benefits also include features such as a reinforced terminal box, improved protection of the IP55 terminal box cover, a steel fan cover and compatible feet. During installation, the following designs can be used: IM B3, IM B35, IM B5, IM B14, IM B34. The electric motor 1AL-80M2-4 therefore represents a reliable three-phase drive for operations that need compact dimensions, a solid mechanical foundation and stable operation in day-to-day industrial use.
