Electric motor 1AL-561-2 0.09 kW for compact industrial drives
Electric motor 1AL-561-2 is a three-phase asynchronous electric motor from the 1AL series intended for standard and more demanding operations in a compact design with a aluminium frame. With an output of 0.09 kW, a 2-pole design and a rated speed of 2700 rpm at a frequency of 50 Hz, it offers fast and stable operation wherever precise movement of smaller mechanisms and space-saving dimensions are important. The rated voltage of 230/400 V and connection Delta/Y make it easy to integrate into standard three-phase systems.
The 56 frame size predestines this model for use in equipment where installation space is limited and reliable operation during a normal working cycle is expected at the same time. It is precisely in such applications that the combination of a compact body, stable speed and a design ready for everyday industrial use is important.
Technical features that help in practice
The motor operates with a power factor of 0.77 and an efficiency of 62 %. The rated current is 0.47 A at 230 V and 0.27 A at 400 V, which provides a solid basis for correct electrical sizing. During starting and transient states, the values of starting torque ratio 2.2, breakdown torque ratio 2.1 and starting current ratio 5.2 are also important. These parameters are particularly relevant in smaller technologies, where reliable start-up, smooth operation and correct behaviour during repeated starting are monitored.
The service factor of 1.0 corresponds to rated operating conditions. Operating modes S1, S2, S3 and S4-S9 are available, so the motor is suitable for both continuous and intermittent operation according to the nature of the equipment. The parabolic or linear load characteristic also expands the possibilities of its integration into technologies with different load profiles during the working cycle.
Durability and reliable operation in an industrial environment
The 1AL-561-2 model is designed for an environment where long-term operation and protection of important motor parts are required. The IP55 protection rating provides protection against dust and splashing water. The IC411 cooling method supports a stable thermal regime during operation. Insulation class F and temperature rise B correspond to reliable deployment in industrial conditions.
Running quality is supported by a vibration velocity of 2.8 mm/s in class A and noise of 57 dB(A). In smaller equipment, laboratory modules or auxiliary production mechanisms, quiet operation is often just as important as the output itself. The motor can rotate in either direction, which makes it easier to use in reversing or universal assemblies. Balancing is dealt with using a half key. On both the DE and NDE side, bearings 6201-2Z are used and lubrication is provided by No. 2 lithium-based grease.
Where this model naturally fits in
The character of the motor corresponds to smaller drives that need fast running and reliable operation without excessive space requirements. In practice, it is used in drives for small conveyors, material feeders, labelling units, packaging modules, sorting mechanisms and dosing stations. It also has its place in fan assemblies, extraction units, smaller pumps, simple mixers, service lines, laboratory equipment, filling modules and auxiliary production tables.
In such equipment, the combination of compact design, speed and smooth operation is often particularly important. An electric motor with an output of 0.09 kW and a speed of 2700 rpm therefore fits well into technologies where lower power is transmitted, but reliable mechanical movement and trouble-free operation in repeated cycles are expected.
Mounting, connection and flexibility of the 1AL series
From an installation point of view, the motor is equipped with cable glands 2-M20X1.5. The packaging dimensions of 220 × 130 × 175 mm and the packaged weight of 4 kg make handling easier during storage, transport and service replacements. The rotor inertia of 0.00018 kg·m² adds information about the motor’s behaviour during start-up and changes in operating state.
The 1AL series is available in mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34, which brings greater flexibility when designing machines and integrating them into different types of equipment. The series concept also includes high compatibility, the option of replacing the front cover, compatible feet, a reinforced terminal box, improved IP55 terminal box protection, a steel fan cover, a carefully designed frame to increase cooling efficiency and reinforced bearings. For specific technological solutions, the motor is suitable for starting by the DOL method and also for control by a frequency converter or soft starter.
A practical choice for smaller industrial assemblies
Electric motor 1AL-561-2 combines a compact frame, fast operation, IP55 protection and a design ready for everyday industrial use. In smaller mechanisms and auxiliary drives, it provides stable operation, space-saving dimensions and good integration into technologies where reliability, simple connection and trouble-free operation matter.
