Electric motor 0,75 kW, 680 rpm, 400 V, 1AL-100L1-8

Prepared for installation in production units with regular operation

Electric motor 1AL-100L1-8 is a solution for machines and technological units where a calm working rhythm, reliable mechanical mounting and trouble-free commissioning are expected. The output of 0.75 kW together with a rated speed of 680 rpm makes this model an 8-pole drive suitable where movement should proceed evenly and without sudden reactions. This character is useful in filling lines, dosing augers, smaller belt conveyors, sorting tables, labelling modules, circulation pumps, ventilation sections, drying tunnels, mixing vessels with lighter loads and auxiliary rotating mechanisms. In these devices it is important that the motor does not create unnecessary shocks after installation and that its operation can be maintained for a long time at a steady pace.

From a practical point of view, the constructional size itself also helps. The 100 mm frame is suitable for both compact and more universal machine assemblies, where an industrial design needs to be combined with reasonable space requirements. The packaging dimensions of 405 × 230 × 295 mm and the packaged weight of 23 kg make handling easier during storage, transport and preparation for installation. The motor can rotate in either direction, which gives greater flexibility when integrating the motor into various mechanical arrangements. The design includes cable glands 2-M25X1.5, so connection can be solved in the standard industrial way without the need for improvisation.

Bearings, balancing and calm mechanical operation

In operation, how the motor behaves after being coupled with the the machine’s mechanical system is also decisive. This model uses 6206-2Z bearings on both the DE and NDE sides, which creates a solid foundation for regular operation and secure rotor mounting. A vibration velocity of 2.8 mm/s in class A support smooth running, which is important when coupled to a pulley, coupling or another transmission element. Half-key balancing is practical for standard connection to industrial machinery. The rotor inertia of 0.0095 kg·m² shows that the motor responds sensibly during starting and when the operating state changes. In practice, this helps especially in equipment where movement is repeated throughout the shift. For example, when conveying packaging, during smooth rotation of products, when sorting piece material or when dosing granulate and powders, it is not desirable for the mechanical system to receive unnecessarily harsh impulses.

Electrical connection without complex integration

Electric motor 1AL-100L1-8 is designed for supply of 230/400 V at 50 Hz with Delta/Star connection. The rated current is 4.00 A at 230 V and 2.3 A at 400 V, which simplifies the design of protection, switching and the overall electrical connection in a standard industrial network. The motor supports DOL, is suitable for control by a frequency inverter and equally for use with a soft starter. This gives greater flexibility when designing the machine. For simple devices, direct starting may be an advantage, while for more sensitive mechanics a gentler start-up or adjustment of operating speed may be preferable. The model is part of the 1AL OPTIMAL series, which is based on an aluminium construction, rapid commissioning and good compatibility in industrial applications.

Power, speed and behaviour under load

At 0.75 kW, this is not a drive intended for high-speed energy transmission. Its benefit lies in the fact that it can reliably drive equipment where power is transmitted continuously, smoothly and without the need for an harsh start. The rated speed of 680 rpm is suitable for technologies where material is conveyed, mixed, circulated or dosed at a uniform pace. This is important, for example, in smaller packaging lines, in guide conveyors, in liquid circulation in process circuits, in lighter agitators, in drying with controlled air flow or in work tables that are to move calmly and precisely.

The ratio of starting torque of 2.0 to rated torque gives the motor a good basis for reliable starting. The ratio of breakdown torque of 1.8 helps maintain operation during normal changes in resistance and the ratio of starting current of 4.0 is important for the design of protection and starting. The load type is intended for a parabolic or linear load characteristic, so the motor naturally fits into operations with fans and pumps, but also into mechanical tasks with smooth feed and a regular working cycle.

Operating conditions it can handle

In everyday use, resistance to the environment and thermal stability are also important. The IP55 rating helps protect the motor in environments with dust, atmospheric moisture and normal industrial contaminants. IC411 cooling supports heat dissipation under standard load and insulation class F together with a temperature rise B creates a suitable basis for reliable operation over longer working intervals. The service factor of 1.0 corresponds to standard industrial use and the available modes S1, S2, S3 and S4-S9 allow the motor to be used in continuous operation as well as in repeated cycles. 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 smooth operation in equipment that works in a compact hall or closer to the operator. The bearing arrangement uses No. 2 lithium-based grease.

Electric motor 1AL-100L1-8 is suitable for operations where installation should be straightforward, operation stable and the mechanical and electrical aspects easy to manage from the very first fitting. It offers an 8-pole character, a compact 100 mm frame and an industrial design ready for regular service in a wide range of production and service equipment.
