AC motors are viable power sources for a range of applications due to their flexibility, efficiency and quiet operation. General uses for AC motors include pumps, water heaters, lawn and garden equipment, ovens, and off-road motorized equipment.

This article looks at the two most common types of AC motors: induction and synchronous. These electric motors do not run at synchronous speed with the current, hence their name. They use the electromagnetic induction phenomenon for transforming the electric power into mechanical power. Induction motor rotors are the most common type of AC motor and are used for various types of pumps, compressors, and other machines.

Different types of motors and their use

Electric motors play an essential role in almost every industry. Using the right type of motor with high-quality parts and regular servicing keeps your facility running smoothly and prevents damage to the endpoint equipment due to wear or power surges.

Gainesville Industrial Electric can help your company select the right industrial electric motors and parts for your applications. Electric motors are machines that convert electrical energy—from either stored power or a direct electrical connection—into mechanical energy through the production of rotational force.

The two major types of electric motors are:. Both AC and DC motors use electrical current to produce rotating magnetic fields that, in turn, generate rotational mechanical force in the armature—located on the rotor or stator—around the shaft. The various motor designs use this same basic concept to convert electric energy into powerful bursts of force and provide dynamic levels of speed or power. While electric motors may differ from one design or type to another, many of them contain these parts and assemblies located from the center working outward :.

AC and DC motors are broad categories of motors that include smaller subtypes. Induction motors, linear motors, and synchronous motors, for example, are all types of AC motors.

Each motor type has different advantages that make them best suited for different commercial and industrial applications. AC motors , for example, are flexible and easy to control. Some of their other advantages include:. AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

Both AC and DC motors find application in processes and facilities in almost every industry. Some of the most common industrial applications for AC motors include:.

Three-Phase Induction Motor – Construction, Working, Types & Applications

Alternating Current AC is what power companies transmit through the electric wires. AC travels in both directions and is used so that transformers may raise and lower the voltage. Electric generators produce low voltage electricity and transformers are used to raise the voltage for long distance transmission. The power supplied at electrical outlets in homes is V or V single-phase. Single-phase means that only one voltage waveform is applied to the motor. Three-phase is more efficient and economical and is provided to industrial sites for heavy-duty equipment with three-phase motors.

AC motors are highly flexible in many features including speed control VSD - Variable Speed Drives and have a much larger installed base compared to DC motors, some of the key advantages are:. The current trend for VSD is to add more features and programmable logic control PLC functionality, which add advantages but require greater technical expertise during maintenance. In this type of motor, the rotation of the rotor is synchronized with the frequency of the supply current and the speed remains constant under varying loads, so is ideal for driving equipment at a constant speed and are used in high precision positioning devices like robots, instrumentation, machines and process control.

This type of motor uses electromagnetic induction from the magnetic field of the stator winding to produce an electric current in the rotor and hence Torque. These are the most common type of AC motor and are important to industry due to their load capacity, with Single-Phase induction motors being used mainly for smaller loads, for example in household appliances whereas, Three-Phase induction motors are used more in industrial applications including compressors, pumps, conveyor systems and lifting gear.

Types of AC motors - Classification and uses of alternating current motors

We all know that without electricity, we cannot do any of our job. If we look into the world we live in, the major development in technology and civilization took place only after the introduction of electricity and electrical devices. So it is quiet evident that electricity and electrical equipments play a vital role in every inch of our life.

The motor is used to convert an electrical form of energy into mechanical form. According to the type of supply, motors are classified as AC motors and DC motors. In today post, we will discuss the different types of three phase induction motors with working and applications.

An AC motor is an electric motor driven by an alternating current AC.

Motors are mechanical or electro-mechanical devices that convert energy into motion. Energy, in the form of electrical, hydraulic, or pneumatic, is converted to rotational or linear motion and then output to a shaft or other power transmission component where it provides useful work. Electrical motors include AC or DC varieties, which are further broken out by specific special purpose electrical motors, including gearmotors, stepper motors, servomotors, and linear motors. Hydraulic and pneumatic motors rely on fluid oil, air for their motive power.

As we know, an electric motor plays a vital role in every sector of the industry, and also in a wide range of applications. There are a variety of types of electric motors are available in the market. The selection of these motors can be done based on the operation and voltage and applications. The main function of field winding is to produce the fixed magnetic field, whereas the armature winding looks like a conductor which is arranged within the magnetic field. Because of the magnetic field, the armature winding uses energy to generate an adequate torque to make the motor shaft turn. Currently, the classification of the DC motor can be done based on the winding connections, which means how the two coils in the motor are connected with each other.
