Electric motor 5,5 kW, 2900 rpm, 400 V, 1AL-132S1-2

Electric motor 1AL-132S1-2 5.5 kW for equipment where speed and uncompromising performance matter

In operations where the line starts up repeatedly, material moves without interruption, and the technology must keep to the rhythm throughout the whole shift, the drive is often one of the most important parts of the entire assembly. Electric motor 1AL-132S1-2 from VYBO Electric is ready for exactly this type of work. It is a three-phase asynchronous electric motor with an output of 5.5 kW, a 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 makes it easy to integrate into industrial electrical systems, where the motor is expected to deliver reliable daily performance and stable behaviour under working load.

The 132 frame size gives this model a solid structural base for technologies that need a brisk drive with genuine working reserve. In practice, such a motor excels in conveyor lines, fan assemblies, extraction systems, pumping modules, mixing units, filling stations and packaging technologies, where the equipment operates regularly and without unnecessary downtime. What matters here is not only the power figure itself, but also how the motor handles longer running periods, repeated starts and the normal industrial environment.

Key design considerations

The motor operates with a power factor of 0.88 and an efficiency of 85.7%. The rated current is 10.1 A at 400 V and 6.09 A at 690 V, which is an important figure for the design of the power supply, protective devices and the overall electrical solution. In this power category, it is already a drive with a clear working role in the technology. It is not enough for it to merely start up. It must be able to operate stably, without unnecessary fluctuations, and with confidence in the daily production cycle.

The good reputation of this model is also based on its starting behaviour. Starting torque ratio 2.2, breakdown torque ratio 2.3 and starting current ratio 7.5 create the conditions for a firm entry into operating mode. For equipment driving conveyor belts, fans, extraction, mixing or process pumping, this kind of start is very important. It helps keep the line running smoothly and predictably even when the load changes according to the working phase of the process.

It is not only about power, but also about operational confidence

1AL-132S1-2 is suitable for operating modes S1, S2, S3 and S4-S9. This means it can be used in continuous operation as well as in technologies where the motor is regularly switched on, interrupted or run in cycles. The service factor of 1.0 corresponds to rated operating conditions, and the parabolic or linear load characteristic broadens the range of possible uses in different kinds of mechanical tasks.

In practice, this makes a great deal of sense. Air handling units need a reliable rhythm and stable running. Conveyor systems, in turn, need a dependable start and continuous output. With agitators, filling stations or pumps, the ability of the motor to handle regular operation without unnecessary disturbance in the entire drive train is also important. This model is set up precisely for such conditions. Its parameters do not merely look good on paper. In the equipment, they translate into smoother starts, stable running and better operational predictability.

A construction that behaves professionally even during longer use

The motor is made in an aluminium frame and operates with IP55 protection. In an industrial environment, this is an important combination. Protection against dust and splashing water helps in daily use in production halls, workshops, plant rooms and operations where the motor is exposed to a harsher working environment. IC411 cooling supports a stable thermal regime during longer loading. F insulation class and B temperature rise complete the technical basis that matches professional industrial use.

From the point of view of mechanical behaviour, the motor operates with a vibration velocity of 2.8 mm/s in class A and a noise level of 80 dB(A). The motor can rotate in either direction, which expands the design possibilities for the equipment. The balancing is solved with a half key. On both the DE and NDE sides, 6308-2Z bearings are used and lubrication is provided by No. 2 lithium-based grease. All these details together create a motor that feels solid, clear and reliable in everyday work.

Mounting solution without unnecessary complications

The motor is fitted with cable entries 2-M32X1.5, which corresponds to its power class and industrial use. The 500 × 290 × 340 mm packaging dimensions and a packaged weight of 40 kg are important for logistics, handling and planning service interventions. The rotor inertia of 0.0377 kg·m² complements the picture of the drive’s behaviour during starting and when the operating state changes.

The 1AL OPTIMAL range offers mounting arrangements IM B3, IM B35, IM B5, IM B14 and IM B34, which makes it easier to integrate into new equipment as well as into modernisations of existing technologies. The strengths of this platform include high compatibility, an reinforced terminal box, sophisticated IP55 terminal box protection, a steel fan cover, compatible feet, the option to replace the front cover and a frame designed for efficient cooling. The motor is suitable for start-up by DOL method and, according to the requirements of the operation, also for control by a frequency converter or soft starter.

Electric motor 1AL-132S1-2 is exactly the type of drive that an operation notices mainly because it works reliably, keeps the pace and does not make the technology the weak point. For equipment where fast running, a robust construction and readiness for regular working load are required, it is a very strong and practical choice.
