Electric motor 7,5 kW, 2900 rpm, 400 V, 1AL-132S2-2

Electric motor 1AL-132S2-2 7.5 kW for operations where the drive must maintain output even at a high working pace

When a production line runs without pauses, ventilation must maintain stable output and pumping or conveyor technology must not lose its rhythm, the quality of the drive becomes clear very quickly. Electric motor 1AL-132S2-2 from VYBO Electric is designed precisely for such an environment. It is a three-phase asynchronous electric motor with an output of 7.5 kW, 2-pole design and rated speed of 2900 rpm at a frequency of 50 Hz. The rated voltage of 400/690 V with Delta/Wye connection corresponds to industrial use, where reliable operation, stable mechanical performance and certainty in everyday working load are expected.

The 132 frame size gives this model a solid base for technologies that already require more significant output while still wanting to retain sensible mounting dimensions. In practice, this means a motor ready for conveyor systems, fan assemblies, extraction units, circulation pumps, filling stations, mixing technologies, dosing units, packing lines, sorting mechanisms, handling workstations, assembly units and service technology assemblies. In all of these applications it is important that the drive can work quickly, evenly and without unnecessary operational compromises.

Here, power reserve also matters

At an output of 7.5 kW, more is expected from the motor than reliable starting alone. Its ability to carry a regular working load throughout the entire shift while maintaining calm behaviour is also important. The 1AL-132S2-2 model operates with a power factor of 0.88 and an efficiency of 87%, making it a strong foundation for technologies that need a high-speed drive with a good operational result. The rated current is 13.56 A at 400 V and 8.20 A at 690 V, which is an important figure for power supply design and for the correct setting of the electrical part of the equipment.

Starting parameters are also highly important. A starting torque ratio of 2.2, a breakdown torque ratio of 2.3 and a starting current ratio of 7.5 describe a motor that is ready for a firm transition into operating mode. In equipment where a fan, pump, conveyor system or technological unit with a regular cycle is driven, this kind of certainty at start-up is reflected in smoother operation of the entire plant. The result is not only output on paper, but also greater operational predictability.

Operation that adapts to the real rhythm of the technology

1AL-132S2-2 is suitable for operating modes S1, S2, S3 and S4-S9. This makes it suitable for continuous processes as well as equipment where the motor is regularly switched on, interrupted or operates under changing load. The service factor 1.0 corresponds to rated working conditions and the parabolic or linear load characteristic broadens its usability in various types of industrial mechanisms.

Such characteristics have real value in practice. Conveyor lines need stable feed, ventilation needs steady running, pumping sets need reliable output and mixing technologies need a regular working rhythm. A motor of this class must handle more than a one-off start. It must retain operating certainty even during longer running periods, under changing load and in operation where the pace is set by the production process itself. That is exactly where the advantage of a structurally robust and operationally balanced drive becomes clear.

Durability without unnecessary weak points

The motor is built in an aluminium frame and operates with IP55 protection, which provides protection against dust and splashing water. In both standard and more demanding industrial conditions, this is an important foundation of reliability. IC411 cooling supports a stable thermal regime under higher working load. Insulation class F and temperature rise B complete the technical profile of a motor ready for regular deployment in production, engineering and the technical background of operations.

From a mechanical point of view, the motor operates with a vibration velocity of 2.8 mm/s in class A and noise of 80 dB(A). The direction of rotation can be in both directions, which makes the design of universal and reversing solutions easier. Balancing is provided with a half key. On the DE and NDE sides, 6308-2Z bearings are used and lubrication is provided by No. 2 lithium-based grease. This design gives the motor a reliable mechanical basis for long-term working deployment.

A mounting solution that leaves room for equipment design

In equipment of this power class, how easily the motor can be integrated into the technology is also important. The 1AL-132S2-2 model is fitted with cable glands 2-M32X1.5. The packed dimensions of 500 × 290 × 340 mm and packed weight of 43 kg are important for logistics, handling and planning service interventions. The rotor inertia of 0.0499 kg·m² also adds to the picture of the motor’s behaviour during starting and when the operating state changes.

The 1AL OPTIMAL range is available in mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34, which expands the options for fitting into new machines as well as upgraded technologies. The 1AL OPTIMAL platform is known for high compatibility, proven quality and an excellent balance between quality and price. Practical benefits also include compatible feet, the possibility of replacing the front cover, a reinforced terminal box, an improved IP55 terminal box cover seal, a steel fan cover, a carefully designed frame to increase cooling efficiency and reinforced bearings. The motor is suitable for DOL starting and, depending on operational requirements, also for control by a frequency converter or soft starter.

Electric motor 1AL-132S2-2 is a solution for operations that do not want to compromise between speed, output and reliability. In equipment where the drive must cope with an intense working pace every day while still maintaining stable operation, it offers a convincing combination of power reserve, robust construction and practical readiness for real industrial deployment.
