The electric motor is the electro-mechanical machine that converts electrical energy into mechanical energy. In simpler words, the device that produces rotational force is known as the motor. The electric motor’s working principle mainly depends on the interaction of the magnetic and electric fields. The main types of electric motors are two which are AC motor and a DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
A Single Phase Induction Motor comprises a single-phase winding which is mounted on the stator of the motor and a cage winding placed on the rotor. A pulsating magnetic field is produced, when the stator winding of the single-phase induction motor is energized by a single-phase supply. The field builds up in one direction falls to zero and then builds up in the opposite direction. Under these conditions, the rotor of an induction motor does not rotate and hence this motor is not self-starting.
IEC General Purpose motors are electric motors that have metric dimensions and work on AC power. They adhere to the electrical and dimension standards of the International Electrotechnical Commission (IEC) instead of the National Electrical Manufacturers Association (NEMA). These motors are mainly used outside the US to power fans, pumps, conveyors, and compressors which require IEC electrical standards.
In locations where potentially explosive gases or vapors are present on a regular basis, an explosion motor is used. It is built in such a way that it will contain an explosion within if one were to occur in the motor and also to prevent the release of harmful gases or vapors into the immediate area that could be explosive too.
In case of a fire in a tunnel, dispersing the toxic fumes quickly and efficiently can be lifesaving. So it is, therefore, necessary to use specialized certified smoke extraction motors for fans in tunnels and other confined spaces
In AC induction motor which is also referred to as a wound rotor motor, slip rings are used not for transferring power, but for inserting resistance into the rotor windings. A wound rotor motor uses three slip rings which are mainly made of copper or copper alloy mounted to the motor shaft. Each slip ring is connected to one of the three phases of rotor windings. The slip ring brushes, made of graphite, are connected to a resistive device, such as a rheostat.
