Electric motor 1AL-160M1-2 11 kW for operations where certainty in power supply, start-up and longer loading is decisive
Electric motor 1AL-160M1-2 from VYBO Electric is a three-phase asynchronous electric motor designed for industrial equipment that operates at a high pace and requires reliable operation throughout the entire shift. This model operates at an output of 11 kW, has a 2-pole design and, at a frequency of 50 Hz, reaches a rated speed of 2930 rpm. The rated voltage of 400/690 V with Delta/Star connection provides a suitable basis for industrial systems where correct electrical sizing, reliable start-up and stable output under regular load are important.
The frame size 160 corresponds to a power category that is commonly used in practice in technologies with a greater requirement for smoothness and operational reliability. The 1AL-160M1-2 model is naturally suited to conveyor systems, fan assemblies, extraction units, pumping modules, mixing technologies, sorting nodes, packaging workplaces, handling lines and technological assemblies where the motor operates regularly and for long periods. In such equipment, reliable start-up, stable speed and a design prepared for everyday industrial use are important.
Electrical data important for equipment design
From the perspective of technology design, the motor operates with a power factor of 0.89 and an efficiency of 88 %. The rated current is 19.4 A at 400 V and 11.71 A at 690 V, which is important when selecting protection, designing the power supply and setting the entire drive branch. In equipment with regular operation, these data are essential for the correct functioning of the electrical part as well as for the stability of the entire technology.
Starting parameters are also important. A starting torque ratio of 2, a breakdown torque ratio of 2.2 and a starting current ratio of 7.5 correspond to a motor that is ready for a firm start into its operating mode. For conveyors, this means reliable start-up of the transport line, for fans a stable entry into operation, for pumps a confident start of the working cycle and for mixers a balanced start of movement. In technologies that are started repeatedly during a shift or operate under changing load, these characteristics are very important.
Design prepared for long-term operation
Electric motor 1AL-160M1-2 is manufactured in an aluminium frame and operates with protection class IP55. In an industrial environment, this is a practical combination, because the motor is protected against dust and splashing water. This is important in production halls, engineering operations, technological rooms and equipment where the drive is expected to operate reliably under normal daily load.
Cooling IC411 supports a stable thermal regime during longer working use. Insulation class F and temperature rise B complement the technical basis suitable for regular and long-term operation. In the 11 kW power class, these are data that have great significance in practical use, because they influence the stability of the motor under higher load and during repeated operation throughout the entire shift.
Mechanical stability and operating quality
The motor operates with a vibration velocity of 2.8 mm/s in class A and noise levels of 86 dB(A). Balancing is solved with a half key and the motor can rotate in either direction, which broadens the range of applications in different types of equipment and mechanical assemblies. In practice, this is especially important where a more universal machine solution is being designed or where reversible operation is required.
On the DE and NDE sides, bearings 6309-2ZC3 are used. Lubrication is ensured by No. 2 lithium-based grease. Such bearing arrangement creates a reliable basis for regular operation in industrial conditions, where the motor is expected to run for longer periods, start repeatedly and behave mechanically stably under load.
Operating modes for different types of working cycle
The 1AL-160M1-2 model is suitable for modes S1, S2, S3 and S4-S9. This means broad application possibilities in continuous operation as well as in processes where the working load is regularly interrupted or changes according to the specific operation. The service factor of 1.0 corresponds to rated working conditions and the parabolic or linear load characteristic broadens its usability in technologies with different courses of mechanical resistance.
Such operational flexibility is important in equipment that ensures material transport, extraction, technological pumping, mixing or repeated movement of the working unit. The motor can be incorporated into production systems with different pacing and different modes of operation without being limited to just one type of use.
Installation, connection and practical integration into the technology
From the installation point of view, the motor is equipped with cable glands 2-M40X1.5, which corresponds to its power class and industrial use. The packaged weight of 83 kg and rotor inertia of 0.055 kg·m² complete the picture of handling, logistics and behaviour during start-up. These data are important when designing the motor mounting, for service planning and when choosing the appropriate method of handling in operation.
The motor is suitable for starting by the DOL method. According to the requirements of the technology, it is also suitable for control by a frequency inverter or soft starter, which broadens the possibilities of its use in controlled drives and more modern technological assemblies.
Briefly about the 1AL OPTIMAL platform
The 1AL OPTIMAL series is available in mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34. Its advantages include high compatibility, a reinforced terminal box, sophisticated protection of the terminal box cover to IP55, a steel fan cover, compatible feet, the option to replace the front cover and a frame designed for efficient cooling.
1AL-160M1-2 offers a combination of 11 kW output, 2930 rpm speed, IP55 protection and a design prepared for long-term working use. For technologies where reliable start-up, stable operation and durability during regular operation are important, this model represents a solid and professional choice.
