Electric motor 11 kW, 970 rpm, 400 V, 1AL-160L-6

Electric motor 1AL-160L-6 for reliable commissioning and stable 6-pole operation

Electric motor 1AL-160L-6 from VYBO Electric is a 6-pole three-phase model with an output of 11 kW, rated voltage of 400/690 V, frequency of 50 Hz and rated speed of 970 rpm. It is a version for technologies where a regular working rhythm, firm mechanical mounting and trouble-free integration into industrial operation are expected. In practice, what matters most is that the motor runs smoothly and maintains an even pace even under longer loading. Such a character is suitable for equipment where the drive should not react rashly, but should support the stable operation of the entire system.

The constructional size of 160 mm already indicates that this model is ready for regular deployment in technological assemblies, where not only performance is important, but also confidence during handling, installation and long-term operation. The electric motor is well suited, for example, for central air handling units, larger circulation pumps, mixing systems, belt conveyors, filtration equipment, drying technologies, recirculation circuits, packaging lines, sorting workplaces, extraction systems, process fans and auxiliary drives of production equipment.

Handling, mounting and installation readiness

For a model in this category, it is important that it is ready for practical integration into the technology without unnecessary complications. The packed weight of 93 kg and packed dimensions of 630 × 330 × 390 mm help with planning storage, transport and the actual installation. Balance with a half key makes it easier to connect correctly with a pulley, coupling or another transmission element. The design includes cable glands 2-M40X1.5, which simplifies neat power supply routing and a clear solution of the machine’s electrical part.

The motor can rotate in either direction, so the motor adapts well even to equipment where the final arrangement of the drive is determined only during installation or when commissioning the technology. In service and installation practice, this is especially practical where the equipment is assembled on site, where the drive is being replaced or where the concept of the line is fine-tuned only after the individual units have been installed.

Bearings and mechanical confidence under regular loading

On both the DE and NDE side, bearings 6309-2RZC3 are used. Such a solution supports reliable rotor mounting under everyday loading, during longer operation and during repeated starts. No. 2 lithium-based grease is suitable for common industrial conditions. Vibration of 2.8 mm/s at vibration grade A helps maintain a refined mechanical performance, which is important in equipment where more precise technological parts are connected to the drive or where quieter operation of the entire line is required. Noise level of 73 dB(A) corresponds to the industrial character of this version.

For a 6-pole motor with a rated speed of 970 rpm, mechanical stability is very important. In conveyors it helps with more even material movement. In mixers and pumps it supports an even working regime. In fans and air handling systems, the benefit is that the drive fits better into processes where continuous and calm operation without unnecessarily sharp reactions is valued.

Control, starting and operating mode

Electric motor 1AL-160L-6 is suitable for direct-on-line starting DOL, for control by a frequency converter and for operation with a soft starter. This broadens the range of its use from fixed industrial drives to technologies where a gentler start or better adaptation of the working rhythm to the process itself is required. In pumping and ventilation applications, regulation can be an advantage. In mixing, material handling or packaging workplaces, a more refined start-up and more even mechanical behaviour are often beneficial.

The starting torque ratio of 2.0 helps overcome the initial resistance of the equipment without an uncertain start-up. The breakdown torque ratio of 2.1 supports stability during load fluctuations. The starting current ratio of 6.5 is important for the design of the electrical branch and protective elements. The motor is intended for a parabolic or linear load curve, so it naturally suits applications with constant resistance as well as processes where the working load changes according to the operating point. The rotor inertia of 0.0116 kg·m² supports a clear response during starting and during control.

The service factor of 1.0 and operating modes S1, S2, S3 and S4-S9 give this model very good usability in both continuous and intermittent operation. In lines that run continuously throughout the shift, as well as in equipment with repeated cycles, this is important for reliable use in practice.

Durability in an industrial environment

Enclosure IP55 helps protect the internal parts of the motor against dust and operational moisture. Cooling IC411 supports a stable thermal regime under regular loading. Insulation class F and temperature rise B create a suitable basis for everyday industrial use. The motor is designed for an ambient temperature of up to +65 °C and an altitude of up to 1000 m, so it can be reliably used in standard and warmer operating conditions.

The 1AL OPTIMAL series from VYBO Electric represents professional low-voltage electric motors in an aluminium frame for wide industrial use. The platform is designed for quick commissioning, excellent value for money and proven quality in real-world conditions. Mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34 are also available.

A drive suited to a long-term operating regime

Electric motor 1AL-160L-6 is suitable where the drive is expected to provide a solid mechanical solution, balanced 6-pole operation and readiness for regular industrial deployment. This model combines practical installation certainty, reliable operational durability and a working character that suits technologies focusing on stability and smoothness.
