Protective Insulation
Protective Insulation

The outer covering of the machine contains casting of iron and aluminum that protect it from environmental oxidation or corrosion. This protective insulation is a strong yield against environmental hazards.

What Is IE3 Series Motors?

The working of IE3 series motors is mainly based on the principle of electromagnetism. For the machine’s excellent performance, the device must acquire less input voltage and be approved by IEC. Due to this feature, this machine is known as the IE3 series motor. The cylindrical body of the machine contains an outer covering of Steel. The protective shield of aluminum or iron is present on the entire surface of the machine, which protects it from environmental effects and keeps it resistive.

One of its body structures, such as the rotor, is correctly installed in the device, improving the machine’s rotation. Due to the reliability and ease of management, IE3 series motors are broadly used at industrial and commercial levels. The robust features of this device make it prominent among all. Primarily used in the mining, pharmaceutical, steel, and textile industries.

What Is IE4 Series Motors
Construction and Structure of IE5 Series Motors

Construction and Structure of IE3 Series Motors

The prominent structure of the IE3 series motor makes it IEC certified and an excellent product of Longbank. This low-voltage motor contains the following constructive elements.

The rotor

The rotor is the rotatory part of the machine that gives mechanical support to the device. Sometimes rotor is also known as an armature that centrifuges the machine at an optimum rate. As the current flows by the device, it interacts with its magnetic field, leading to the shaft’s rotation. The magnets which are present in the Stator can be temporary or permanent.

The Stator

The machine’s Stator contains small silicone sheets, electromagnetic wires, and resistive paint. The Stator of the device is its core component that may have windings or a permanent magnet. Small silicone sheets in Stator protect the energy loss and make it protective. These embedded sheets in Stator are known as laminations.

The bearings

Bearings of the device on its support the shaft and ensure the proper lubrication of oil film when the motor performs its function. The machine’s bearings improve its service life and make it reliable for several positions. Bearings also keep a specific distance between the Stator and rotor of the device. For holding the load, bearings also contain the shaft. As the shaft is outside the machine’s body, it is also known as overhung.

The windings

The Windings are the circular parts outside the poles or Stator of the device. As the current starts flowing through the magnet, it will produce a magnetic field. The structural configuration of the winding can be salient or non-salient. Most devices contain temperature-measuring instruments on the stator windings.

The air gap

The air gap that will be discussed here is the gap between the rotor and the Stator. This gap plays an integral role in the proper functioning of the machine. Such as, if the gap between the rotor and Stator becomes large, the device’s magnetic field may reduce and lead to low efficiency. Conversely, if the gap between the Stator and the router reduces significantly, it can produce friction that may lead to noise and energy crises.

The commutator

The commutator is an electrical switch between the external circuit and the Stator. Its primary function is to reverse the nature of directional current, such as from AC into DC. Structurally this part is composed of copper wires and leads to the unidirectional current.

Here all those parts described above are present in the IE3 series motor. These parts are externally closed with a cover to protect them from environmental conditions.
