Electric motor 0,18 kW, 645 rpm, 400 V, 1AL-80M1-8

Electric motor for smooth and controlled operation

Electric motor 1AL-80M1-8 with an output of 0.18 kW belongs among 8-pole solutions designed for operations where smooth running, lower speeds and a predictable drive response are important. The nominal speed of 645 rpm at a frequency of 50 Hz gives this model the character of a low-speed industrial motor that is suitable for equipment with an emphasis on even operation. It is used, for example, in smaller conveyors, dispensers, sorting tables, feed modules in production lines, packaging units, rotary work tables, mixers with lighter loads, fan sections, extraction modules and smaller pumping sets. In such applications, high speed is not decisive, but rather regular motion and stability during longer operation.

Power supply and integration into technology

The motor is designed for 230/400 V at 50 Hz and uses a Delta/Wye connection. The nominal current is 1.37 A at 230 V and 0.79 A at 400 V, which makes it easier to select protection devices, switching components and the power supply design in a standard industrial network. In operation, it is important that this model can be started by direct-on-line starting DOL, controlled by a frequency inverter or used with a soft starter. This gives greater freedom in machine design. In a simple device, the motor can operate in direct connection, in more sensitive mechanics the start-up can be softened, and in technologies that require adjustment of the working pace an inverter can be used. Such a solution is practical for material dosing, smooth product conveying, gentle drive of a rotating element and equipment where the motor is frequently switched on and off.

Starting, torque and behaviour under load

The ratio of starting torque 1.9 and the ratio of breakdown torque 1.8 to nominal torque mean that the motor has confidence during start-up and during normal load changes. The starting current ratio of 3.3 helps to estimate the electrical behaviour at start and correctly set the protective elements in the technology. This model is intended for a parabolic or linear load curve, so it is naturally suitable for driving fans, circulating pumps, smaller conveyor sections, winding mechanisms, feed tables or lighter mixing assemblies. In operation, this means that the motor is used where motion needs to be maintained without sudden shocks, with sufficient reserve for start-up and with a good basis for a longer working cycle. The 0.18 kW output has a clear purpose in such use. It is not intended for heavy-duty power transmission, but for reliable and precise fulfilment of smaller drive tasks in an industrial environment.

Protection and operating conditions

For stable industrial operation, enclosure and thermal resistance are also essential. This electric motor has an IP55 degree of protection, so it is ready for environments where dust, moisture and industrial contaminants are commonly present. IC411 cooling supports effective heat dissipation in standard use, and insulation class F together with a temperature rise B creates a suitable basis for reliable operation. The service factor is 1.0 and the motor is designed for S1, S2, S3 and S4-S9 duty cycles, which broadens the possible use from continuous operation to cyclic operating modes. It can be used at an ambient temperature of up to +65 °C and at an altitude of up to 1000 m. The noise level of 52 dB(A) helps to maintain smooth operation of the equipment, especially where individual machines are located closer to the operator or in compact production areas.

Compact design and mechanical reliability

The model uses an 80 mm frame, so it fits well into equipment with limited installation space. The stability of the rotating part is supported by 6204-2Z bearings on both the DE and NDE sides. A vibration velocity of 2.8 mm/s in class A contribute to quiet operation when connected to a pulley, coupling or another transmission element. The motor can rotate in either direction, and the half-key balancing helps with standard connection to the mechanism. The design includes cable glands 2-M20X1.5. Rotor inertia of 0.0025 kg·m² supports a brisk response at start-up and during changes in operating state. During handling, the compact packaging dimensions of 320 × 220 × 260 mm and packaging weight of 13 kg are helpful. The bearing arrangement is prepared with No. 2 lithium-based grease. This model is part of the 1AL OPTIMAL series, which represents professional low-voltage electric motors from VYBO Electric in an aluminium frame for standard and more demanding operations.

Electric motor 1AL-80M1-8 is a suitable choice for technologies where smooth motion, compact dimensions and reliability in everyday use are decisive. It combines low speed, industrial IP55 protection, flexible control options and a mechanically stable design that integrates well into a variety of production and service equipment.
