Electric motor 7,5 kW, 970 rpm, 400 V, 1AL-160M-6

Electric motor 1AL-160M-6 for equipment with smooth and reliable operation

Electric motor 1AL-160M-6 from VYBO Electric is suitable for technologies where the drive is required to operate steadily, without unnecessary sharp reactions and with good reliability under long-term load. This 6-pole three-phase motor with an output of 7.5 kW and a rated speed of 970 rpm is naturally used in pumping sets, air handling units, mixing equipment, belt conveyors, filtration systems, drying technologies, recirculation circuits, packaging lines, sorting modules, extraction systems and drives of auxiliary production mechanisms. In such operations it is important that the motor does not run hastily, but keeps a balanced working rhythm and cooperates well with the the machine’s mechanical system.

It is precisely the combination of 6 poles and a rated speed of 970 rpm that gives this model a character suitable for processes with an emphasis on smoothness. In fans it helps maintain a regular system operation. In pumping technologies it supports the stability of the operating mode. In mixers and recirculation systems, the advantage is calmer movement without an unnecessarily abrupt start. When conveying material, sorting or in packaging equipment, the more predictable behaviour of the drive during the entire shift is also appreciated.

Why it is suitable for technologies with regular load

The motor is designed for a parabolic or linear load curve, so it fits well into applications with constant resistance and into processes where the load changes according to the operating point. In practice, this is important where the technology does not operate in the same way all the time, but the drive must adapt to the course of the process. The rotor inertia of 0.081 kg·m² supports a balanced response during starting and control. The motor therefore does not feel unnecessarily rigid, while at the same time retaining confidence when transitioning between operating states.

The operating modes S1, S2, S3 and S4-S9 give this model a wide range of uses. It fits well into continuous operation as well as into equipment with an intermittent cycle. In technologies running continuously throughout the working shift, long-term stability is important. With repeated starts and changes in the working rhythm, it also helps that the motor is ready for regular cyclical loading within the specified operating modes.

Electrical arrangement and control options

Electric motor 1AL-160M-6 operates with a rated voltage of 400/690 V and a connection of triangle/star. This design makes it easier to integrate into industrial three-phase systems where the drive is expected to have a reliable and clearly defined connection. The motor is suitable for direct-on-line starting, for control by frequency converter and for operation with a soft starter. This expands the possibilities of its use from fixed drives to technologies where a softer start or better adaptation of the working speed to the process itself is beneficial.

In ventilation systems and pumping circuits, the option of regulation according to the current demand is useful. In mixing, conveying or packaging mechanisms, a calmer start-up is also an advantage, as it places less strain on the adjoining mechanics. The service factor 1.0 corresponds to stable working duty under rated conditions and supports reliable use in regular industrial operation.

Construction, protection and working environment

The frame size of 160 mm gives the motor a solid base for equipment where mechanical reliability and long-term use are expected from the drive. The IP55 protection helps protect the internal parts of the motor from dust and operational moisture. This is important in production halls, technical rooms and in building services equipment. IC411 cooling supports a stable thermal regime under regular load and helps maintain reliable operation during longer working cycles.

Insulation class F and temperature rise B create a suitable basis for daily use in industrial conditions. The motor is intended for an ambient temperature of up to +65 °C and an altitude of up to 1000 m. Vibration of 2.8 mm/s at vibration class A supports smooth mechanical operation, which is particularly useful where more precise technological parts are connected to the drive. The noise level of 73 dB(A) corresponds to the industrial character of this model.

Mechanical readiness and installation into the machine

On the DE and NDE sides, bearings 6309-2RZC3 are used, which support reliable rotor mounting under regular load and repeated starts. No. 2 lithium-based grease is suitable for common industrial operating conditions. Balancing with a half key makes it easier to connect correctly with a pulley, coupling or other transmission element. The design includes cable glands 2-M40X1.5, which helps with a neat power supply connection and a clear cable layout in the technological unit. The motor can rotate in either direction, so the motor also adapts well to equipment where the final arrangement of the drive is determined only during installation or commissioning.

The 1AL OPTIMAL series from VYBO Electric represents professional low-voltage electric motors in an aluminium frame for a wide range of industrial applications. The platform is known for quick commissioning, very good value for money and proven quality in real operating conditions. If required, mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34 are also available.

Stable drive for technologies that must run without fluctuations

Electric motor 1AL-160M-6 is suitable wherever the equipment needs a robust 6-pole motor with a balanced working performance, a reliable mechanical base and readiness for long-term operation. With this model, VYBO Electric offers a solution that fits well into technologies emphasising regularity, smooth operation and reliability in everyday use.
