What is an armature?

The so-called armature for fire pump is a component that plays a key and pivotal role in the motor’s process of converting mechanical energy and electrical energy. The armature is a part of the motor that is equipped with coils, and the relative movement of the coil to the magnetic field. In a generator, an induced electromotive force is generated in a coil that is subjected to force to generate electricity.

As is known to all, one of the important parts of fire pump is the armature, its armature structure, the improvement of technology, is a good prerequisite for fire pump operation. The armature consists of inner core and outer copper wire winding.

First, The fire pump armature core

In general, the armature iron core used in fire pump is fixed on the rotor support or the rotating shaft. The surface of the iron core is evenly distributed with teeth and grooves, and the groove is for inserting the discharge pivot winding, which is also called copper wire. In addition, iron cores are generally laminated with silicon steel sheets coated with insulating varnish about 0.5 mm thick, because such cores can reduce hysteresis and eddy current loss by rotating in the main magnetic field.

Second, Copper winding

Copper windings are also called armature windings. In the absence of special requirements, the armature windings are embedded in an armature iron core slot with a coil made of insulated copper wire and connected to a commutator. The delicate fire pump must pay attention to the insulation between the coil and the iron core, and between the upper and lower layers of the coil when making the armature. Generally, it is pressed with a wedge and then fastened with glass ribbon or steel wire. The armature winding is the core component of the fire pump, and it is the key to the generation of induced electromotive force and electromagnetic torque in the motor during its operation to realize energy conversion.

The armature of a fire pump, in elaborate terms, is very elaborate. This point, professionals are even aware of it. General fire pump senior production companies, in the production of fire pump armature are very experienced, but also good at avoiding the wrong details. Therefore, when buying a fire pump, it is very necessary to look for a senior company!
