Electric motor 1AL-561-4 for compact drives in industry
Electric motor 1AL-561-4 from the 1AL OPTIMAL series is a three-phase asynchronous motor with an output of 0.06 kW, rated voltage of 230/400 V, connection Delta/Y and a 4-pole design. At a frequency of 50 Hz, it reaches rated speed of 1300 rpm. This is a compact model with a frame size of 56, suitable where a small installation space, neat drive mounting and stable operation throughout the entire working shift are important.
Thanks to the smaller frame and low noise level of 48 dB(A), this motor is well suited to technologies where quiet machine operation is important. In practice, it is used in light conveyors, dosing equipment, labelling units, sorting modules, laboratory mechanisms, packaging assemblies, small fans, compact pumping units, mixing units with lower load, feed mechanisms and automated lines with precisely controlled movement.
Operating parameters with a clear meaning
This model operates with a rated current of 0.38 A at 230 V and 0.22 A at 400 V. Motor efficiency reaches 56 % and power factor 0.7. The starting torque ratio of 2.1, breakdown torque ratio of 2 and starting current ratio of 4 provide confidence when designing the drive and when integrating it into an existing machine. What is especially important is that the motor behaves predictably at start-up and is well suited to mechanisms where repeatable starting is required without unnecessarily complicated adjustment.
The service factor of 1.0 and operating duty types S1, S2, S3, S4-S9 broaden the range of applications. The motor can operate in continuous duty, as well as in cyclic processes where load, pause and restart alternate. The rotor moment of inertia of 0.0003 kg·m² supports a brisk response of the drive in smaller machines where movement accuracy, rapid response and good control of the mechanical process are important.
Construction prepared for everyday production
The 1AL OPTIMAL series is among the best-selling solutions from VYBO Electric. It is designed as a low-voltage platform for standard as well as more demanding operations in an aluminium frame. For the 1AL-561-4 model, the IP55 protection rating is important, helping protect the internal parts of the motor from dust and splashing water. Industrial operation therefore gains a drive that is well suited to production halls, service technologies and technical units with increased demands for reliability.
IC411 cooling supports a stable thermal regime during longer loads. The motor uses insulation class F and temperature rise B, which is important for long-term operating reserve. The maximum ambient temperature of +65 °C and suitability for altitudes up to 1000 m provide broader application options even where the technology is subject to higher thermal demands. Vibration at the level of 2.8 mm/s in class A helps maintain quiet and stable operation of the entire assembly.
Bearings, control and installation readiness
6201-2Z bearings are fitted on both the DE and NDE sides. Lubrication is provided using No. 2 lithium-based grease in the relevant temperature class. Half-key balancing is practical when fitting couplings, pulleys and other transmission elements. The motor supports DOL starting and is also suitable for control by a frequency inverter or soft starter. This provides greater flexibility when setting the start-up and adapting the operation to a specific machine.
The design includes 2-M20X1.5 cable glands. Compact logistics are also practical. The packaged weight is 4 kg and the packaging dimensions are 220 × 130 × 175 mm. For servicing, storage and quick drive replacement, this is an advantage that saves space and makes handling easier. The motor can rotate in either direction, which expands usability in equipment with reversing or where a variable drive arrangement is required.
1AL OPTIMAL as a professional solution
1AL OPTIMAL offers very good value for money, proven quality and quick commissioning. The series is known for high compatibility, availability of various modifications and the option of mounting designs IM B3, IM B35, IM B5, IM B14, IM B34. The 1AL-561-4 model is a suitable choice for operations that need a small three-phase electric motor with IP55 protection, quiet operation and parameters ready for reliable everyday work. In compact machines, auxiliary technology modules and precise production units alike, it offers a clean, professional and proven drive solution.
