80 mm frame as a solid base for a compact industrial drive
Electric motor 1AL-80M1-4 from the 1AL OPTIMAL series is a three-phase asynchronous electric motor with an output of 0.55 kW, a rated voltage of 230/400 V and a connection of Delta/Y. At a frequency of 50 Hz it reaches a rated speed of 1390 rpm and operates in a 4-pole version. The 80 mm frame, that is an shaft height of 80 mm, offers a good balance between compact dimensions and mechanical reliability in everyday operation. This design is well suited to production machines, technical modules and standalone drive units, where the assembly should be clear and the drive should fit reliably into the entire system.
In practice, this model is often used for belt conveyors, packaging equipment, filling lines, labelling systems, sorting workstations, fan units, pump modules, mixing units, dosing equipment, feed mechanisms and material handling technologies. In such operations, it is important for the drive to have smooth running, reasonable space requirements and the ability to operate reliably even with repeated starting or longer loading.
Performance and electrical values for stable line operation
The output of 0.55 kW is suitable for machines that need a compact electric motor with a certain operating reserve. The rated current is 2.50 A at 230 V and 1.44 A at 400 V, which allows straightforward integration into standard industrial systems. Efficiency of 71 % and power factor of 0.75 support economical and balanced operation in applications where the motor runs regularly throughout the shift or in repeated cycles according to the line rhythm.
During start-up, the ratio of starting torque 2.3, ratio of breakdown torque 2.4 and ratio of starting current 5.2 are of practical importance. This combination helps where the drive starts repeatedly, carries light to medium loads and must behave predictably. The load type with a parabolic or linear load characteristic broadens usability in conveyor systems, with fans and with mechanisms whose resistance changes during the working cycle.
Control, direction of rotation and response in operation
The 1AL-80M1-4 electric motor is suitable for DOL starting, for control via a frequency inverter and for a soft starter. This provides greater flexibility when setting the starting process and adapting operation to the specific technology. On simpler machines it can work with direct starting, while on more sensitive mechanisms a gentler start or better speed control helps. The motor can rotate in either direction, which is useful for reversing movements, feed units and technological assemblies where the working direction changes according to the process phase.
An important operating characteristic is also the rotor moment of inertia of 0.0018 kg·m². In equipment with repeated starting, step-by-step transfer or metered movement, it helps maintain a good drive response and a smooth working cycle. In conveyors, packaging modules or filling machines, this property has a direct impact on the stability of the mechanical system and on the smoothness of the entire production operation.
Resistance to the conditions of industrial use
The motor has IP55 protection, which helps protect internal parts from dust and splashing water. In operations where packaging, bulk materials, liquids or regular cleaning of the technology are involved, this is an important element of reliability. IC411 cooling supports a stable thermal regime during longer loading and the frame of the 1AL OPTIMAL series is designed for effective heat dissipation.
Insulation class F and temperature rise B give the motor a suitable basis for everyday industrial operation. It is designed for an ambient temperature of up to +65 °C and an altitude of up to 1000 m. Service factor 1.0 and operating modes S1, S2, S3, S4-S9 allow use in continuous operation as well as in interrupted sequences. Noise level of 58 dB(A) and vibration of 2.8 mm/s in class A support quiet mechanical performance, which is important for machines where smooth running and overall structural stability are monitored.
Mechanical design and the practical side of application
On both the DE and NDE sides, 6204-2Z bearings are fitted. Lubrication is provided by No. 2 lithium-based grease in the relevant temperature class. Balancing with a half key is important when fitting pulleys, couplings and other power transmission elements, where smooth running and a reliable mechanical connection matter. For electrical connection, 2-M20X1.5 cable glands are prepared, which makes integration into standard industrial solutions easier.
The 1AL OPTIMAL series is one of VYBO Electric’s best-selling ranges, with more than 30,000 units installed in industry. The 1AL OPTIMAL series is among the best-selling electric motors from VYBO Electric and has more than 30,000 installed units in industry. It is known for very good value for money, proven quality, high compatibility and quick commissioning. The series also includes elements that are practically important for everyday use, such as a reinforced terminal box, improved IP55 terminal box protection and a steel fan cover. For installation, the IM B3, IM B35, IM B5, IM B14, IM B34 versions can be used. The packaged weight of 10 kg and packaging dimensions of 320 × 220 × 260 mm also make handling easier during storage, transport and service replacement. The 1AL-80M1-4 electric motor is therefore a suitable choice for operations that need a compact three-phase drive with IP55 protection, a solid mechanical base and reliable behaviour in everyday work.
