Electric motor 3 kW, 710 rpm, 400 V, 1AL-132M-8

A solid foundation for slow-speed technologies with a regular duty cycle

Electric motor 1AL-132M-8 is intended for operations in which the drive is assessed not by speed, but by stability, quiet running and the ability to work for long periods in a steady mode. An output of 3 kW at rated speed of 710 rpm makes this 8-pole model a suitable solution for technologies where material is moved, mixed, circulated or dosed at a regular pace. This character is ideal for screw conveyors, belt lines, mixing units, circulation pumps, ventilation assemblies, extraction arms, sorting tables, filling lines, slow-speed rotary units and working modules in packaging technology. In these processes, it is very important that the drive does not force the technology into abrupt reactions, but helps it maintain a balanced working rhythm.

Installation, mechanical mounting and position in the machine

This model uses a shaft height of 132 mm, so it is suitable where a more robust mounting base and certainty in power transmission to the connected mechanics are already expected. This size is well suited to machines with a more robust design, to conveyors with a longer route, to larger mixing vessels, to pumping circuits or to ventilation assemblies, where it is necessary to combine stable operation with an appropriate power reserve. The 6308-2Z bearing arrangement on both the DE and NDE sides supports smooth rotation, and a vibration velocity of 2.8 mm/s in class A contribute to balanced behaviour after coupling with a coupling, pulley or other transmission element. Balance with half key corresponds to common industrial mounting, and the motor can rotate in either direction, which makes it easier to integrate into various machine assemblies without unnecessary design limitations.

When handling, storing and transporting, the packaging dimensions of 540 × 310 × 340 mm and the packaging weight of 45 kg are helpful. The design includes cable glands 2-M32X1.5, so the electrical connection can be prepared in line with the usual industrial standard. The rotor inertia of 0.0395 kg·m² supports a balanced response during start-up as well as when changing the operating state, which is especially important where the equipment passes through several phases of the duty cycle.

The importance of power and speed in specific processes

At 3 kW and 710 rpm, this is a drive that naturally suits processes with smoother power transmission. In practice, this means that when mixing tank contents, it is easier to maintain regular movement of the medium, on a conveyor the material moves at a calmer pace, on a filling line the continuity of individual steps is easier to stabilise, and on a fan or pump assembly a steady operating mode can be maintained without unnecessarily abrupt changes. This model therefore also fits well into technologies with long daily running times, where repeatability, even loading and reliable response with every subsequent start are important.

The starting torque ratio of 2.0 to the rated torque gives the motor a solid base at start-up. The breakdown torque ratio of 1.8 helps it handle common changes in working resistance, and the starting current ratio of 6.0 is important for the correct design of electrical starting and protection. In technologies with cyclical operation, this means the motor can also be used where the equipment repeatedly starts during a shift, where the load changes according to the process phase, or where a secure start-up without excessive mechanical shock is required. The model is intended for a parabolic or linear load curve, so it is well suited to a wide range of industrial applications with smooth or regularly distributed resistance.

Electrical connection and operating durability

Electric motor 1AL-132M-8 is designed for 230/400 V supply at 50 Hz with Delta/Star connection. The rated current is 12.87 A at 230 V and 7.4 A at 400 V, which provides a clear basis for the design of fusing, contactors and protective elements in the control panel. The motor is suitable for DOL, for control by a frequency inverter and for use with a soft starter. This broadens its possible application from simple stand-alone machines to technologies where gentler starting or adjustment of working speed is required. Such a solution is practical for transport routes with more sensitive product transfer, for material dosing, for mixing with variable resistance, or for circulation circuits where the start-up of the whole system needs to be set sensibly.

For everyday operation, protection against the environment is also important. IP55 protection helps protect the motor in conditions with dust, moisture and normal industrial contaminants. IC411 cooling supports heat dissipation under standard load, and the combination of insulation class F with a temperature rise of B creates a suitable thermal basis for regular long-term operation. The service factor of 1.0 corresponds to standard industrial use. Operating modes S1, S2, S3 and S4-S9 are available, so the motor can be used in continuous operation as well as in repeated duty cycles. It is intended for an ambient temperature of up to +65 °C and an altitude of up to 1000 m. Noise level of 64 dB(A) supports smooth operation in halls where several machines work side by side.

The model belongs to the 1AL OPTIMAL series, which represents professional low-voltage VYBO Electric motors in an aluminium frame for a wide range of industrial use. Electric motor 1AL-132M-8 offers a solid mechanical foundation, balanced 8-pole operation and parameters that make sense where the technology needs to work calmly, reliably and without unnecessary fluctuations throughout operation.
