How electric motors are constructed ??? By: Sardorbek,Javohir,Rasulbek and Laylo The electric motor construction can be done using the rotor, bearings, stator, air gap, windings, commutator, etc. The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power. Working of Electric Motor - Basically, most of the electric motors work on the electromagnetic induction principle, however, there are different types of motors which uses other electromechanical methods namely piezoelectric effect and electrostatic force.
- The basic working principle of electromagnetic motors can depend on the mechanical energy that works on the conductor using the flow of electric current & it is placed within the magnetic field. The mechanical force direction is perpendicular toward the magnetic field and the conductor and the magnetic field.
Types of Electric Motor AC Motor
AC motors are classified into three types namely induction, synchronous, and linear motors
- Induction motors are classified into two types namely single phase and three phase motors
- Synchronous motors are classified into two types namely hysteresis and reluctance motors
DC Motor
DC motors are classified into two types namely self-excited and separately excited motors
- Self-excited motors are classified into three types namely series, compound and shunt motors
- Compound motors are classified into two types namely short shunt and long shunt motors
- The applications of electrical motor include the following.
- The applications of electrical motor mainly include blowers, fans, machine tools, pumps, turbines, power tools, alternators, compressors, rolling mills, ships, movers, paper mills.
- The electric motor is an essential device in different applications like HVAC- heating ventilating & cooling equipment, home appliances, and motor vehicles.
Advantages of Electrical Motor✅ - The primary cost of these motors are low compared with the fossil fuel engines, but the horsepower rating of both are similar.✔
- These motors are extremely efficient & automatic control permits for automatic start & stop functions.✔
- These motors include moving parts, so the lifespan of these motors are longer.✔
Disadvantages of Electric Motor - Large electric motors are not easily movable, and consideration should be made for the exact voltage and current supply
- In some situations, expensive line expansions are mandatory for isolated areas where electrical power is not accessible.
- Usually, the performance of these motors is more efficient.
