Similar to an induction motor, the stator is made and has a controllable supply with three phase. Isolated by non-magnetic spacers, the rotors include longitudinal iron laminations.

The synchronous motor is classified into two types they are reluctance and the hysteresis motor. Reluctance Motor — The motor whose types of electric motors process is similar to an induction motor and which runs like a synchronous motor is known as the reluctance motor.

Hysteresis Motor — The hysteresis motor is the type of a synchronous motor which has the uniform air gap and does types of electric motors have any DC excitation system.

The torque in the motor is produced by the hysteresis and the eddy current of the motor.

Its work depends on the basic principle that when a current carrying conductor is placed in a magnetic field, then a force exerted on it, and torque develops. The DC motor is classified into two types, i. Separately Excited Motor The motor in which the DC winding is excited by the separate DC source is known as types of electric motors separately excited dc motor.

With the help of the separate source, the armature winding of the motor is energised and produce flux.


The rotor aligns itself with the magnetic field of the stator, while the stator field windings are sequentially energized to rotate the stator field. The magnetic flux created by the field windings follows the path of least magnetic reluctance, meaning the flux will flow through poles of the rotor that are closest to the energized types of electric motors of the stator, thereby magnetizing those poles of the types of electric motors and creating torque.

As the rotor turns, different windings will be energized, keeping the rotor turning. SRMs are used in some appliances [72] and vehicles. Universal motor Modern low-cost universal motor, from a vacuum cleaner.

Field windings are dark copper-colored, toward the back, on both sides. The rotor's laminated core is gray metallic, with dark slots for winding the coils.

The commutator partly hidden has become dark from use; it is toward the front. The large brown molded-plastic piece in the foreground supports the brush guides types of electric motors brushes both sidesas well as the front motor bearing.


A commutated electrically excited series or parallel wound motor is referred to as a universal motor because it can be designed to operate on AC or DC power. A universal motor can operate well on AC because the current in both the field and the armature coils and hence the resultant magnetic fields will alternate reverse polarity in synchronism, and hence the resulting mechanical force will occur in a constant direction of rotation.

Operating types of electric motors normal types of electric motors line frequenciesuniversal motors are often found in a range less than watts.

Universal motors also formed the basis of the traditional railway types of electric motors motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid un-laminated iron and they are now rarely used.

An advantage of the universal motor is that AC supplies may be used on motors that have some characteristics more common in DC motors, specifically high starting torque and very compact design if high running speeds are used. The negative aspect is the maintenance and short life problems caused by the commutator.

Such motors are used in devices, such as food mixers and power tools, that are used only intermittently, and often have high starting-torque demands.

Your Guide to the Different Types of Electric Motors

There are a number of different kinds of motor available, and the types of electric motors choice will not only depend on your budget, but also on what type of application you intend to run.

After reading this guide, you should have a better appreciation of the type of motor you need to purchase — then you can start to think about power outputs and budget.


Three-Phase Electric Motors Three-phase types of electric motors motors are the most powerful and efficient commercial motorsand as a result, they are usually found in large commercial applications such as lifting gear, large conveyors and heavy duty compressors. But what exactly is a three-phase electric motor and can they be used on a v mains power?

The electricity you get from the grid is supplied as alternating current.
