Electric motor 1,5 kW, 1400 rpm, 400 V, 1AL-90L-4

Electric motor 1AL-90L-4 for reliable operation of lines, pumps and air-handling systems

In production, what often decides is how smoothly the motor runs from the first start-up and how easily it is integrated into the entire technology. Electric motor 1AL-90L-4 from the 1AL OPTIMAL series is ready for exactly this kind of use. It is a three-phase asynchronous electric motor with an output of 1.5 kW, a rated voltage of 230/400 V, connection Delta/Y and rated speed of 1400 rpm at a frequency of 50 Hz. The four-pole design together with the 90 mm frame, i.e. a shaft shaft height of 90 mm, provides a suitable basis for machines and technological assemblies where the drive should be compact, stable and ready for regular operation.

This model is naturally used in conveyor lines, packaging machines, filling units, mixing assemblies, fan modules, pump units, labelling technologies, dosing mechanisms, sorting workplaces, feed systems, closing equipment and automation systems. In such applications, it matters that the motor handles the continuous rhythm of the line and repeated starts without an unnecessarily erratic character. For equipment where movement precision, regular timing and clean installation are monitored, it is a practical and professional drive foundation.

Parameters that have a direct effect on machine operation

The rated current is 6.14 A at 230 V and 3.53 A at 400 V. When designing the connection and integrating the motor into existing equipment, these are important values because they help to set the supply and drive protection correctly. The rated speed of 1400 rpm is suitable where a balanced mechanical transfer is expected without an unnecessarily abrupt running character. In technologies with material handling, mixing, airflow or liquid flow, this provides a reliable basis for everyday work.

The motor operates with an efficiency of 78.5 % and a power factor of 0.78. When the load lasts longer, the start-up behaviour is also important. A starting torque ratio of 2.3, a breakdown torque ratio of 2.3 and a starting current ratio of 6 give the motor behaviour suitable for machines where the working cycle is repeated regularly and the drive must respond predictably. The load type with a parabolic or linear load characteristic also broadens usability in technologies with changing movement resistance and in equipment where energy is transferred to a fan, pump or mechanical feed.

Practical advantages in start-up, control and reversing

Electric motor 1AL-90L-4 is suitable for DOL starting, for control by a frequency inverter and also for a soft starter. This combination provides freedom in choosing the starting method according to the specific technology. In simpler equipment, it can remain with direct starting, while more sensitive processes can use a gentler start or better speed control. This is advantageous in dosing equipment, in fan applications and in feed mechanisms where a smoother transition into operating mode is required.

An important feature is also the possibility of rotation in both directions. This capability broadens use in reversing assemblies, in bidirectional transfers or in units where the direction of movement changes according to the phase of the production process. The rotor moment of inertia of 0.0027 kg·m² helps to maintain a good response in applications with repeated start, stop or a short working step.

Durability, cooling and mounting for long-term operation

The motor has IP55 protection, which helps to protect internal parts against dust and splashing water. In an industrial environment, this is essential for machines that operate in production halls, in material processing and in technologies with regular cleaning. Thermal stability is ensured by IC411 cooling, which together with a frame designed for efficient heat dissipation supports reliable operation under longer load. The motor uses insulation class F and temperature rise B, so it is ready for everyday industrial duty in industrial conditions.

It is intended for an ambient temperature of up to +65 °C and an altitude of up to 1000 m. The service factor 1.0 and duty types S1, S2, S3, S4-S9 allow use in continuous operation as well as in intermittent cycles. Noise level 61 dB(A) and vibration 2.8 mm/s in class A contribute to a refined mechanical character, which is important in equipment where several drives operate side by side and the stability of the entire assembly is monitored.

On the DE and NDE sides, 6205-2Z bearings are fitted and lubrication is provided by No. 2 lithium-based grease in the appropriate temperature class. Balancing with a half key is important when fitting pulleys, couplings and other power transmission elements where even running matters. Practical importance also lies in the 2-M25X1.5 cable glands, which support a neat electrical connection.

The 1AL OPTIMAL series in professional use

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. It is an innovative low-voltage platform in an aluminium frame for standard and demanding operations, with very good value for money, proven quality and broad compatibility. Practical value is also provided by features such as a reinforced terminal box, sophisticated IP55 terminal box cover protection, a steel fan cover or compatible feet. During installation, versions IM B3, IM B35, IM B5, IM B14, IM B34 can be used. The packaging weight of 14 kg and packaging dimensions of 380 × 210 × 270 mm also make storage, transport and service handling easier. Electric motor 1AL-90L-4 therefore represents a reliable drive for operations that need solid technical support, smooth running and easy integration into everyday production.
