Electric motor 18,5 kW, 2930 rpm, 400 V, 1AL-160L-2

Electric motor 1AL-160L-2 18.5 kW for technologies where continuous operation and solid operational reliability are important

In many industrial operations, it is not only the motor output itself that matters, but above all how it behaves during continuous working, repeated starting and longer loading under real conditions. Electric motor 1AL-160L-2 from VYBO Electric is designed precisely for this kind of environment. It is a three-phase asynchronous electric motor with an output of 18.5 kW, a 2-pole design and rated speed of 2930 rpm at a frequency of 50 Hz. The rated voltage of 400/690 V with Delta/Wye connection corresponds to industrial electrical systems where reliable power transfer and stable operation in a higher output class are required.

The 160 frame size moves this model into the field of technologies where the motor forms one of the load-bearing parts of the drive. In equipment that ensures continuous movement of material, stable extraction, media circulation or a regular mixing process, the drive must work without unnecessary fluctuations. This is exactly where the 1AL-160L-2 fits in naturally. It is well suited to conveyor systems, fan assemblies, extraction units, circulation pumps, mixing technologies, packaging lines, sorting nodes, dosing assemblies, handling workplaces and technological systems where a high-speed motor with a solid output reserve is needed.

A reliable basis for more powerful industrial drives

The 1AL-160L-2 model operates with a power factor of 0.9 and an efficiency of 90%. The rated current is 31.6 A at 400 V and 19.11 A at 690 V. For equipment of this class, these are important values for power supply design, protection and the overall electrical solution. The output of 18.5 kW combined with a speed of 2930 rpm creates a suitable basis for technologies that require a brisk drive and stable performance during a longer working cycle.

During starting, the motor behaves with parameters that correspond to its output level. A starting torque ratio of 2.3, a breakdown torque ratio of 2.2 and a starting current ratio of 7.5 are suitable for equipment where the motor starts repeatedly or where it must quickly move into a steady operating mode after start-up. In practice, this is appreciated by a conveyor line with regular run-up, a fan unit with an emphasis on even operation, and a pumping or mixing system that needs certainty at every start.

Design for industrial environments and regular load

The electric motor 1AL-160L-2 is made in an aluminium frame and operates with IP55 protection. This protection is important wherever the motor encounters dust, normal operating moisture or splashing water. In industrial halls, technical rooms, engineering operations and technological assemblies alike, this is a practical advantage because the drive is ready for daily deployment in a real working environment. IC411 cooling supports a stable thermal regime under higher load and during longer operation. F insulation class and temperature rise B complete a structural basis suitable for regular operation in high-performance equipment.

From the mechanical point of view, the motor operates with a vibration velocity of 2.8 mm/s in class A and a noise level of 86 dB(A). Balancing is provided with a half key and the motor can rotate in either direction. This gives greater flexibility in machine design and in solutions where reversal or more universal mounting of the drive is required. On both the DE and NDE sides, 6309-2ZC3 bearings are used. Lubrication is provided by No. 2 lithium-based grease, which corresponds to industrial deployment in this output class.

Operating modes suitable for modern production processes

The motor is suitable for operating modes S1, S2, S3 and S4-S9. This means wide deployment options in continuous operations as well as in processes where operation is regularly interrupted or changes according to the working operation. The service factor of 1.0 corresponds to rated operating conditions and the parabolic or linear load characteristic expands usability in various types of technological equipment. In one plant this model can ensure smooth transport, in another air handling, elsewhere a pumping process or regular movement of a production unit.

For the starting method, the motor is suitable for DOL. It is also suitable for control by means of a frequency inverter or a soft starter, if the specific technology setup requires it. In practice, this is a useful feature when modernising equipment, when controlled starting is required or when the drive operation needs to be adapted more precisely to a specific task.

The 1AL OPTIMAL platform and mounting flexibility

The 1AL-160L-2 model belongs to the 1AL OPTIMAL range, which is known for excellent value for money, high compatibility and proven quality in industrial practice. The series is available in mounting arrangements IM B3, IM B35, IM B5, IM B14 and IM B34, which makes installation into new machines and modernised equipment easier. Practical advantages of the platform include a reinforced terminal box, improved IP55 terminal box protection, a steel fan cover, compatible feet, the option to replace the front cover, a carefully designed frame to increase cooling efficiency and reinforced bearings.

The motor is equipped with cable entries 2-M40X1.5. Rotor inertia of 0.124 kg·m² adds to the picture of behaviour during starting and when the operating state changes. The electric motor 1AL-160L-2 therefore represents a solution for technologies that need an output of 18.5 kW, a speed of 2930 rpm, IP55 protection and a design ready for stable and long-term industrial operation.
