Electric motor 1,1 kW, 905 rpm, 400 V, 1AL-90L-6

Electric motor 1AL-90L-6 for reliable operation in technologies with a steady working rhythm

Electric motor 1AL-90L-6 from VYBO Electric is a 6-pole three-phase motor designed for operations where smooth running, assured start-up and good control over the operating pace of the equipment are important. The output of 1.1 kW and rated speed of 905 rpm at a frequency of 50 Hz create a drive character that is well suited where the motor is expected to provide a regular and calm transfer of energy. This design is suitable for fans, extraction units, circulation pumps, conveyor lines, mixing equipment, filtration technologies, packaging machines, dosing units, sorting lines, drying modules and various auxiliary drives in production and in technical building equipment.

It is precisely the 6-pole solution that gives this model an operating behaviour which supports continuity. When conveying material, circulating a medium or driving elements that are meant to work without sudden changes, this is a practical feature. The motor does not create an unnecessarily fast working rhythm. It fits better into processes where the technology is to run steadily throughout the entire shift and where a clear mechanical response is important.

Power supply, wiring and commissioning

Model 1AL-90L-6 operates with a rated voltage of 230/400 V and with connection △/Y. The rated current is 5.25 A at 230 V and 3.02 A at 400 V, which is important when designing the supply branch, protection and also when sizing control elements. When commissioning the technology, this helps prepare the drive so that it is correctly matched to the electrical part of the equipment and so that its operation remains stable even under regular load.

The electric motor is suitable for direct DOL starting, for control by frequency converter and for operation with a soft starter. In practice, this expands the possible uses. In simpler systems it can operate as a fixed drive with direct starting. In regulated processes, the start-up and operating speed can be better adapted to the specific task. This is important, for example, in ventilation, where the power demand changes, in dosing, where feeding accuracy is monitored, or on conveyors, where smoother behaviour is appreciated during starting and while running.

Starting characteristics and behaviour under load

An industrial motor must be reliable not only once the speed has stabilised, but also at start-up itself. Electric motor 1AL-90L-6 has a starting torque ratio of 2.1, which helps overcome the initial resistance of the equipment without uncertain run-up. The breakdown torque ratio of 2.0 supports stability even when the mechanical load fluctuates. The starting current ratio of 5.5 is important for electrical design and for the correct setting of protection elements during start-up.

The motor is intended for a parabolic or linear load curve. This means it can naturally be used in applications with steady resistance as well as in assemblies where the load changes according to the current operation. For circulation pumps, fans, mixers, conveyors, filtration units or packaging mechanisms, this is an important prerequisite for reliable everyday operation. The rotor inertia of 0.0035 kg·m² supports a balanced response during start-up and during control, so the motor responds clearly without an unnecessarily harsh or delayed reaction.

Protection, cooling and operating conditions

In an industrial environment, resistance to ordinary operating influences is also decisive. IP55 protection shields the motor against dust and operating moisture, which is important in halls, plant rooms and in equipment operating in more demanding surroundings. IC411 cooling supports a stable thermal regime during longer working cycles. The F insulation class and B temperature rise create a suitable basis for reliable operation under continuous and intermittent load.

The motor is designed for an ambient temperature of up to +65 °C and for an altitude of up to 1000 m. The service factor of 1.0 and the operating modes S1, S2, S3 and S4-S9 give this model good usability in constant processes as well as in applications with repeated cycles. For technological assemblies that run throughout the entire shift, as well as for equipment with alternating duty and pauses, this is an important practical benefit.

Mechanical design and mounting confidence

The shaft height of 90 mm provides a balanced ratio between compact design and mechanical stability. On both the DE and NDE sides, 6205-2Z bearings are used, which support smooth running and reliable rotor guidance under regular load. The No. 2 lithium-based grease is suitable for normal industrial conditions. Balancing with a half key makes correct connection with the mechanical parts of the equipment easier.

The design includes 2-M25X1.5 cable entries, which helps with a clean and safe supply connection. The motor can rotate in either direction, so the motor is well suited even for constructions where the final arrangement of the drive is determined only during assembly or when commissioning the line. The packaged weight of 14 kg and packaging dimensions of 380 × 210 × 270 mm make logistics, handling and preparation for installation in the machine easier.

The 1AL OPTIMAL series from VYBO Electric represents professional low-voltage electric motors in an aluminium frame for wide industrial use. The emphasis is placed on quick commissioning, a very good price to quality ratio and proven quality in real conditions.

A practical choice for stable industrial operation

Electric motor 1AL-90L-6 combines 1.1 kW power, rated speed of 905 rpm, IP55 protection and flexibility in control. It is suitable for operations that need a reliable 6-pole drive with a smooth working expression, good installation readiness and confidence in everyday use. With this model, VYBO Electric offers a motor that naturally fits into technologies with an emphasis on stability, regularity and long-term operational reliability.
