Electric motor 0,12 kW, 1310 rpm, 400 V, 1AL-63M1-4

Precise drive for machines where both space and smooth running matter

Electric motor 1AL-63M1-4 from the 1AL OPTIMAL series is a three-phase asynchronous electric motor with an output of 0.12 kW, a rated voltage of 230/400 V and a delta/star connection. At a frequency of 50 Hz, it reaches a rated speed of 1310 rpm and operates in a 4-pole version. The 63 frame size provides a good basis for machines and technological units where the drive must handle regular operation while not unnecessarily increasing the size of the entire assembly. This model is suitable where a compact solution with professional technical design and reliable operating behaviour is required.

The 0.12 kW power level is often used in equipment where fine and repeatable movement is important. Electric motor 1AL-63M1-4 is therefore naturally suited to dosing systems, smaller conveyors, sorting tables, laboratory mechanisms, mixing units with lighter loads, packaging machines, labelling modules, fan assemblies, pumping units, feed mechanisms and various automation units. In such operations, it is usually crucial that the motor runs smoothly, stably and without unnecessarily large space requirements.

Parameters that help when designing the drive

The motor has a rated current of 0.73 A at 230 V and 0.42 A at 400 V. Efficiency reaches 57 % and the power factor is 0.72. The starting torque ratio is 2.2, the breakdown torque ratio is 2.1 and the starting current ratio is 4. These data are important when selecting the starting method and when matching the motor with the mechanical part of the equipment. For smaller machines, it is often required that the drive starts cleanly, without unwanted fluctuation and with good repeatability of the operating cycle. It is precisely in such situations that the precisely defined behaviour of the motor during starting and steady running has practical significance.

The rotor moment of inertia of 0.0005 kg·m² supports a brisk response in mechanisms with more frequent changes of state. In equipment where movement is started, interrupted or finely adjusted periodically, this is a useful characteristic. The noise level of 52 dB(A) also helps maintain a more favourable working environment in smaller production lines, service zones and technological units where running quality is monitored. Vibrations at a level of 2.8 mm/s in class A support calm mechanical behaviour and reduced transmission of oscillations into the machine structure.

Design focused on reliable operation

The 1AL OPTIMAL series is designed as a low-voltage platform for standard and more demanding operations in an aluminium frame. For the 1AL-63M1-4 model, an important foundation is the IP55 degree of protection, which helps protect the motor against dust and splashing water. In an industrial environment, this is a practical advantage, especially when the motor is installed in machines with frequent material movement, in technological zones with light contamination or in operations where emphasis is placed on long-term operational reliability.

Thermal stability is provided by IC411 cooling. The motor uses insulation class F and temperature rise B, which provides a suitable reserve for everyday operation. The ambient temperature can reach up to +65 °C and the motor is intended for altitudes up to 1000 m. The service factor of 1.0 and duty types S1, S2, S3, S4-S9 give this model broad deployment options. The electric motor can therefore operate reliably in continuous duty as well as in cyclic processes where load, pause and repeated starting alternate.

Bearings, balancing and control

6201-2Z bearings are fitted on both the DE and NDE sides. Lubrication is provided by No. 2 lithium-based grease in the relevant temperature class. Balancing with a half key is important when fitting pulleys, couplings and other power transmission elements where smooth and even running matters. The motor is suitable for DOL starting, for control by a frequency inverter and also for a soft starter. This combination enables simple integration into common industrial solutions as well as into equipment where a gentler start or better speed adaptation to operation is required.

The motor can rotate in either direction, which expands the application options in reversing mechanisms, feed modules and technologies with a changing working direction. The logistical aspect is also practical. The packaging dimensions are 235 × 140 × 185 mm and the packaged weight is 4.5 kg, so handling during installation, service work and storage remains simple. Within the 1AL OPTIMAL series, mounting versions IM B3, IM B35, IM B5, IM B14, IM B34 are available, which helps with integration into various design solutions. Model 1AL-63M1-4 thus represents a compact industrial electric motor with proven quality, good compatibility and a very good price-quality ratio.
