Construction and Structure of IE5 Series Motors

Construction and Structure of IE4 Series Motors

Longbank manufactures the IE4 series motors, which fulfill all requirements of IEC verification. Therefore these motors are considered the best motors for industrial work. The body structure of IE4 series motors contains the following exceptional components:

The rotor

The rotor is the moving component of the IE4 series motors, which provides the turning force to the motor shaft. Sometimes rotor is also known as the armature of the machine. As the rotor delivers the turning force to the shaft, it provides the mechanical energy. Mainly the conductor’s current is delivered to the magnetic field of the stator, which rotates the shaft of the device. The magnets of the IE4 series motors can be permanent or temporary.

The stator

The stator of the device is mainly composed of magnets or windings, known as the core component of the device. The machine’s stator mainly contains small sheets, which prevents the loss of energy compared to large sheets. These sheets are known as laminations.

The bearings

The bearings of the machine are the supportive structures for the rotating shaft. It keeps the spinning rotor and the stator at a distance. Bearings also carry the motor shaft at a specific place that carries their load. As the shaft is outside the body of the machine, it is also known as the overhung.

The Windings

The windings are the small coils that wound around the magnet’s stator. As the current conducts through these coils, it produces a magnetic field. The overall configuration of the pole windings can be non-salient or salient.

The air gap

The air gap is the non-physical component of the machine, which is the distance between the stator and the rotor. This air gap cannot be neglected because it directly affects the overall efficiency of the IE4 series motor. As the air gap increases, the magnetic field’s strength also reduces the machine’s overall efficiency. However, the highly reduced distance can create friction that may lead to an energy crisis.

The commutator

The commutator is the main component that reverses the unidirectional current of the machine. Such as it changes the direction of current from AC into DC and is mainly manufactured by copper wires. Its primary function is to create the unidirectional current.

These parts described above are premium components not present in an open environment. At the same time, all these are enclosed in a specific box that protects them from environmental fluctuations.
