More AC Electric Motor Information

The AC electric motor is a rotary device that works with electric power without the need to be connected to a warehouse, ie the motor will always be active, working at constant speed. It is common for the alternating current electric motor to be applied generally to industrial machines that operate without interruption, providing a wide advantage as these machines do not need precision in their rotation.

A division of the relevant AC motor is related to the communication and transmission between the transmitter and receiver of the apparatus, which may be synchronous or asynchronous.

There is another division of the AC motor, and this is generally better known, namely: three-phase motors and single-phase motors. Basically, there is a noticeable difference, since each one is fed with a different performance, which brings in a diversity in the starting capacity of the engine. buy CRSTF-PN32

The single-phase motor has a higher limit and needs more capacitors so that it works well, as well as having to be properly sized for better efficiency. The three-phase motor has its operating principle based on the rotating magnetic field, which provides constancy in its speed.


The electric motor of direct current is made of two magnetic structures, being they the stator, that is the field winding or permanent magnet and the rotor, that is the armature winding.

The stator is made of ferromagnetic structure with protruding poles where the coils are rolled, forming the field, or a permanent magnet.

The rotor is an electromagnet made of an iron core with windings which are fed by a mechanical switching system, formed by a switch integral with the rotor axis, having a cylindrical surface with several blades. It is also formed by fixed brushes, which put pressure on the switch.

The function of the switch is to invert the current in the rotation phase so that the torque is always in the same direction. The two sides of the winding are placed in grooves, which have spacing equal to the distance of the two poles of the stator, so when the conductors on one side are on the north pole, the conductors on the other are on the south pole. The coils are connected in series by the switch blades, with the end of the latter connected to the beginning of the first.
