Electric motor 4 kW, 960 rpm, 400 V, 1AL-132M1-6

Electric motor 1AL-132M1-6 for precise integration into three-phase operation

Electric motor 1AL-132M1-6 from VYBO Electric is a 6-pole three-phase model with a rated voltage of 400/690 V, a frequency of 50 Hz and rated speed of 960 rpm. This very combination defines its operating character. The motor is suitable where the drive needs to run smoothly, without an unnecessarily rapid start-up and with good operational calm throughout the whole shift. In equipment that needs a stable rhythm, such operation is practical both during start-up and under long-term load. The power of 4 kW gives this version a good basis for technologies where the drive is expected to work continuously and cooperate reliably with the mechanical part of the machine.

The delta/star connection makes it easier to integrate into standard industrial systems. The electric motor is suitable for DOL, for frequency inverter control and also for operation with a soft starter. This is important in cases where one application requires simple direct connection and another requires a gentler start or regulated operation. In practice, this broadens the possibilities for use in technologies where the operating mode, start-up conditions or the requirement for process smoothness change.

What this model delivers in real operation

The six-pole design with a speed of 960 rpm is naturally suited to equipment where movement should be clear and balanced. That is why the electric motor 1AL-132M1-6 is well used, for example, in recirculation pumps, mixing vessels, air handling units, drum mechanisms, belt conveyors, filtration assemblies, drying units, packaging workplaces, extraction systems and sorting technologies. In some operations, the benefit is a calmer run under steady load. In others, it is that the motor responds well to inverter control and helps better match the drive to the operating cycle of the equipment.

The motor is designed for a parabolic or linear load curve, so it is suitable for applications with continuous resistance as well as for processes where the load changes according to the operating point. In ventilation and pumping this is important for system stability. In conveying and mixing, it is important for regular mechanical behaviour. The rotor inertia of 0.0357 kg·m² supports a balanced response during start-up and during control. The drive therefore does not feel unnecessarily harsh, while at the same time it does not lose clarity when the operating state changes.

Start-up, torque and electrical behaviour

During start-up, the motor offers a starting torque ratio of 2.1. This helps overcome the initial resistance of the equipment without an uncertain run-up. The breakdown torque ratio of 2.1 supports stable running when the load changes or fluctuates briefly. The starting current ratio of 6.5 is important for protection design and correct dimensioning of the electrical branch. The rated current is 9.5 A at 400 V. These data help in the design of the control panel, protective elements and the actual method of commissioning.

The service factor of 1.0 corresponds to stable operating duty under rated conditions. The operating duties S1, S2, S3 and S4-S9 provide this model with a wide range of applications. It can operate in continuous duty as well as in intermittent cycles, depending on how the specific technology is set up. In equipment with repeated starts, this is important for confidence in each subsequent cycle. In lines with continuous operation, it supports long-term operational stability.

Mechanical design and installation readiness

The 132 mm frame provides a solid basis for industrial equipment where regular loading and mechanical stability are expected from the motor. On both the DE and NDE sides, 6308-2Z bearings are fitted, supporting reliable rotor mounting in everyday operation. No. 2 lithium-based grease is suitable for common industrial operating conditions. Balanced with a half key, it makes correct connection to a pulley, coupling or other transmission element easier.

The design includes 2-M32X1.5 cable glands, which helps with clean power supply entry. The motor can rotate in either direction, so the motor adapts well even to equipment where the final drive arrangement is resolved only during installation. The packaged weight of 50 kg and packaging dimensions of 540 × 290 × 340 mm make it easier to plan handling, storage and preparation for installation into the technology.

Durability and working conditions

The motor operates with IP55 protection and IC411 cooling. This helps with deployment in a normal industrial environment where dust, operational moisture and longer working cycles are present. Insulation class F and temperature rise B support a reliable thermal regime. The model is intended for an ambient temperature of up to +65 °C and for an altitude of up to 1000 m. Vibration of 2.8 mm/s at vibration class A contributes to smooth running, which is especially important where the motor operates with more precise parts of the technology.

In the 1AL OPTIMAL platform, this model represents a professional solution for wide industrial use. The series is designed as a low-voltage platform in an aluminium frame, with emphasis on fast commissioning, proven quality and very good value for money. Mounting versions IM B3, IM B35, IM B5, IM B14 and IM B34 are available as required.

Balanced drive for technologies with a regular operating cycle

Electric motor 1AL-132M1-6 is suitable where smoothness, a solid mechanical solution and reliable electrical integration into operation are expected from the drive. In technologies with an emphasis on a stable working rhythm, it delivers confidence during start-up, good readiness for control and a design that corresponds to everyday industrial use.
