 The motor is one of the most important parts of electrical equipment. There are different types of engines and we have talked about them in previous articles. In this article, we will talk about Induction Motor and examine one of its types.

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type.

based on the construction and starting method, the single-phase induction motor is categorized into the four types of Split Phase, Capacitor Start, Capacitor Start Capacitor Run, and Shaded Pole. In the following sections, we will elaborate on each of these types of single-phase induction motors.

 

 

A commutator is a rotary electrical switch in some motors that supplies current to the rotor. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine. Two or more electrical contacts called "brushes" made of a soft conductive material like carbon press against the commutator, making sliding contact with successive segments of the commutator as it rotates, supplying the current to the rotor. The windings on the rotor are connected to the commutator segments.

A commutator itself is a split rotary ring, typically made of copper, with each segment of the ring attached to each end of the armature coil that is used in some types of electric motors and electrical generators whose job is to periodically reverse the current direction between the rotor and the external circuit.
