What Is IEC Low Voltage Motors?

The International Electrotechnical Commission (IEC) Standard IEC 61140:2016 defines low voltage as 0 to 1000 V AC RMS or 0 to 1500 V DC as the low voltage standard. According to IEC 60038, a low voltage supply system is a system with a voltage of 50 to 1000 V AC or 120 to 1500 V DC, which is in reference to the International Electrotechnical Commission Standard Voltages for power distribution systems throughout the world.

There is a common misconception that low voltage refers to the mains voltages used by residential and light commercial consumers, especially in electrical power systems. Despite the fact that low voltage in this context implies a risk of electric shock, there is only a minor risk of electric arcs passing through the air in this case.

An IEC low-voltage motor is powered by electromagnetism, which is the principle of operation. There is actually no need for a large amount of voltage in order for a motor to function, as long as it is done with an IEC-approved machine. The IEC low-voltage motors are therefore also known as IEC low-voltage motors as a result of that fact. There is a cylindrical shape to the machine’s body, which is covered with steel. The machine is protected from environmental hazards by castings made out of aluminum and iron that keep it safe from the elements.

There is an adjustment to be made to the machine motor in the device to make up for proper rotation and to improve performance. Various industries and commercial operations use these motors because of their easy maintenance and reliability.

Construction and Structure of IEC Low Voltage Motors

Longbank’s low-voltage motors are considered one of the finest products we have to offer at Longbank. They have been designed to meet the specifications and performance requirements of both the International Electrotechnical Commission and the European Commission. To create low-voltage motors, several different components will be required to build them, including the following:

The Rotor:

The moving component of the low voltage motors is the rotor, sometimes rotor is called an armature. It provides turning force to the shaft for delivering the mechanical energy. The current of the conductor interacts with the magnetic fields of the stator which helps the shaft rotate.  The magnets of the stator can be permanent or temporary.

The Stator:

The motor’s stator is its core component that can be comprised of permanent magnets or windings. Several small metal sheets are embedded in the stator core to reduce the energy losses instead of a large sheet. These sheets are named laminations.

The Bearings:

The bearing provides support to the rotating shaft. it keeps a specific distance between the spinning rotor and the stator. The bearing also carries the shaft of the motor that is led to hold the load in place. This shaft is located in the outer part of the motor so it can be called overhung.

The Windings:

The windings are the small coils of wires wound around the poles (stator) of the magnet.  When electric current passes through the coils the poles of the magnet begin to produce a magnetic field. The configuration of pole winding can be salient or non-salient.

The Air Gap:

It is a non-physical component of the motor but its importance can’t be neglected. The gap between the rotor and the stator affects the efficiency of the low voltage motor. As this gap increases, the magnetizing ability of the stator reduces. However, the highly reduced can produce noise and also an energy crisis.

The Commutator:

The commutator reverses the direction of the current coming from the external circuit. It converts AC into DC and is composed of copper wires. It helps in the production of the unidirectional current.

Hitherto all the parts of the low voltage motor have been described along with their functions. All these elements are enclosed in an outer covering due to protection reasons.

Features of IEC Low Voltage Motors

Some of the best features of IEC low voltage motors are described here:

  • Some motors are composed of cast iron which makes them highly robust and suitable for their function.
  • Aluminum makes the motor strong, durable, and light in weight.
  • The IEC low voltage motors are water-proofed which is known as IP55 protection.
  • C3 paint system prevents the motor from corrosion.
  • The number of rotors is increased in the motor to enhance its load-lifting capability.
  • The stator can be gamma or V-shaped.
  • The grease collector is usually attached with large motors.
  • The shaft shape can be optimized and also be the windings.
  • Some other accessories are built-in for each low voltage motor like fans, RTDs, and encoders.
  • IEC low voltage motors have small sensors.
  • The motors can bear the temperature of -55oC to 90o
  • The easiest usage method is process performance motors.
  • They have non-drive ends, customized cable ends, and tight seals to keep the dust outside.
  • Most of these motors found their applications on an industrial level.

Advantages of ie5 series Motors

Low voltage motors help you to reduce energy consumption by 10% to 40%. It is one of the best innovations in electronic components. These energy resources can be stored for upcoming generations only if we properly use them. So, in this regard, IEC low voltage motors are of great importance.

  • These motors have high efficiency, low input, and high output.
  • They come in various shapes, sizes, and voltage ranges as well.
  • Less than 600V is needed to perform its activity with great efficiency.

  • Low voltage motors save up to 18 – 160 terawatts- hours per year.
  • Millions of carbon dioxide throughout their lifetime.
  • These are cost-effective motors.

As these motors work on the least energy consumption, some of these energy resources can be saved for future purposes. These highly optimized motors should be installed in different industries to increase the overall yield. Small improvements can lead to the best results only if we apply them at a huge scale.
