Electric motor 1,1 kW, 680 rpm, 400 V, 1AL-100L2-8

When the drive must suit both the power supply and the application

Electric motor 1AL-100L2-8 is an 8-pole model with an output of 1.1 kW, rated speed of 680 rpm and power supply of 230/400 V at 50 Hz. This type of motor makes sense wherever movement is meant to be steady, clear and reliably consistent over the long term. In practice, it is not a drive for high speeds, but a solution for technologies that need a regular working rhythm without unnecessarily abrupt reactions. Such behaviour is welcome on belt conveyors, dosing screws, mixers with light to medium load, circulation pumps, drying modules, fan assemblies, sorting tables, rotary work units, filling machines and also when winding material at a slower pace. In these tasks, it is important that the motor does not force a harsh start on the mechanism, but maintains an operation that transfers well to the whole machine.

Power supply, current and integration into the technology

The electrical side of this model is designed so that it can be naturally integrated into a standard industrial network. The Delta/Y connection at 230/400 V simplifies the power supply design, and the rated current of 5.56 A at 230 V and 3.2 A at 400 V gives the designer and service technician a clear basis for selecting protection, switching and safeguarding. This is especially important for machines that are commissioned without lengthy adjustments and need to move quickly from installation to operating mode. The motor is suitable for DOL, for control by a frequency inverter and for use with a soft starter. Thanks to this, it can be used in a simple stand-alone application as well as in technology where a gentler start or adjustment of the working pace according to the process is required. During filling, mixing, dosing or on conveyor lines with a regular cycle, this helps set the operation so that it is in line with the mechanical system and the subsequent operations.

This is precisely where the practical significance of the 1AL OPTIMAL series becomes apparent. These are professional low-voltage VYBO Electric electric motors in an aluminium frame, designed for standard and more demanding operations, with an emphasis on quick commissioning and good compatibility in industry.

Starting, torque and behaviour in repeated cycles

At a rated speed of 680 rpm, the motor is suitable for processes where power is transmitted smoothly and without the need for high dynamic performance. A starting torque ratio of 2.0 to rated torque means that the motor has solid confidence at start-up. A breakdown torque ratio of 1.8 helps to handle common changes in resistance during operation, and a starting current ratio of 5.0 is important when designing the electrical start-up. These data have a concrete impact on equipment that starts repeatedly during a shift or works in a regular production cycle. On a dosing unit, this means a predictable start of feed. On a pump or fan, it means a steadier run-up without unnecessarily abrupt loading of the system. On a conveyor or rotary table, it is easier to maintain smooth motion transfer.

The motor is designed for a parabolic or linear load curve, which broadens its usability across a wide range of common industrial applications. It is well suited wherever the load rises smoothly, or wherever it remains within a regular range throughout the entire operation. The output of 1.1 kW here is not just a number in a catalogue. In real use, it means a stable foundation for technologies that must run reliably for many hours a day while maintaining a calm working character.

Protection, heat and operating conditions

In an industrial environment, it also matters how the motor withstands dust, moisture and longer operating times. This model has IP55 protection, so it is ready for common production conditions in which the drive encounters industrial contaminants and atmospheric humidity. IC411 cooling ensures heat dissipation at standard load, and the combination of insulation class F with a temperature rise of B creates a suitable thermal reserve for regular and long-term operation. The service factor of 1.0 corresponds to standard industrial use. The operating modes S1, S2, S3 and S4-S9 allow the motor to be used in continuous operation as well as in cyclic processes with intermittent load. Use is intended for an ambient temperature of up to +65 °C and an altitude of up to 1000 m. Noise level of 59 dB(A) supports refined operation in halls where several technologies work side by side or where the operator is closer to the machine.

Mechanical design and practical mounting details

The 100 mm frame size offers a good balance between compact installation space and confidence in mechanical integration into the machine. 6206-2Z bearings on both the DE and NDE sides support stable rotor mounting, and a vibration velocity of 2.8 mm/s in class A contribute to balanced operation when connected to a pulley, coupling or another transmission element. The motor can rotate in either direction, and balancing with a half key corresponds to standard industrial mounting. Rotor inertia of 0.011 kg·m² helps to maintain a reasonable response at start-up and during changes in operating state. The design includes 2-M25X1.5 cable glands. For handling and logistics, the packaging dimensions 405 × 230 × 295 mm and the packaging weight of 25 kg are helpful. The bearing arrangement uses No. 2 lithium-based grease.

Electric motor 1AL-100L2-8 is suitable for operations where the electrical connection must be orderly, the start stable and the mechanical system calm and consistent in operation. It combines an 8-pole design, a 100 mm frame, IP55 protection and a construction ready for everyday industrial use.
