What Is Submersible/Immersible Motors?

Submersible/immersible motors are manufactured based on advanced electromagnetic principles. For the proper working of the machine, they require less energy. Submersible motors work underwater, while immersible work in dry conditions. Due to this season, they are known as submersible/immersible motors. The cylindrical body of the machine with vertical orientation proves that it is easy to manage. The entire body of the device is made up of steel laminated with aluminum that protects the motor from environmental oxidation and makes its performance accurate.

All the body parts of the motor are adjusted accurately, especially the rotor involved in the proper rotation of the machine. Due to its improved feature and easy installation, it is used in numerous industries for commercial and other purposes.

Construction and Structure of IE5 Series Motors

Construction and Structure of Submersible/Immersible Motors

As Longbank adopts all the standards of IEC, the construction of IEC-verified motors is done by this brand. Submersible/immersible consist of the following parts:

The Rotor:

The other name of the rotor is an armature which is the moving component of the low-voltage motors. It helps in providing torque by transferring the mechanical energy to the shaft. The stator generates the magnetic field, which interacts with the electric field to give the turning effects to the rotor. 

The Stator:

The stator comprises permanent or temporary (consisting of windings) magnets. It is considered a core component of the Submersible / immersible. A single large sheet may induce certain energy losses, which are minimized by inserting multiple small metal sheets. These small sheets are also called laminations. 

The Bearings:

The purpose of inserting bearings inside the motor is to support the moving shaft by maintaining a certain distance between the rotor and the stator. These bearings also support the shaft by keeping it in its place. The shaft of the motor is overhung as it is located outside the body of the motor.

The Windings:

The motor’s stator comprises several small coils termed windings, which surround the magnet’s poles. These magnets generate the magnetic field as the current passes through the windings. The arrangement of the pole winding can be salient or non-salient.

The Air Gap:

The air gap is the non-physical component of the motor and can’t be ignored. It helps in controlling the efficiency of low-voltage motors. The narrow range of this distance is needed because the increased distance may reduce the magnetization of the coils. Likewise, the highly reduced distance can generate noise and an energy crisis.

The Commutator:

The most exclusive component of the motor is its commutator. It comprises copper wires that reverse the direction of the flowing current as it interconverts the AC into DC. In this way, a unidirectional current is generated.

All these motor components play a crucial role in controlling the overall efficiency of low-voltage motors. For protection reasons, all the elements are enclosed in an outer covering.
