Which Would Ultimately Cause the Armature in An Electric Motor to Spin?

The electric motor is the heart of every electrical vehicle. You will find them in bikes, cars, trucks, boats, and almost everywhere spent time. But, did you ever think about how an electric motor works and what is the armature inside rotates an electric motor?

Besides, which would ultimately cause the armature in an electric motor to spin? An electric motor consists of three parts: the stator(armature), rotor, and field magnet. When electricity flows through the windings of the stator, it creates a magnetic field around the winding. This causes the rotor to spin.

In the next few paragraphs, we’ll explain more facts and the relationship between armature and motor. So, without further ado, let’s spin–

Which Would Ultimately Cause The Armature In An Electric Motor To Spin?

An electric motor is basically a rotating magnetic field that produces torque on a shaft. The armature is a stationary part of the motor that is connected to the motor shaft. When current passes through the coils of the armature, they produce a magnetic field that rotates around the stator. This rotation causes the shaft to turn.

Here, an armature consists of copper wire wrapped(wire loop) around a core material such as iron or steel. The armature is attached to the shaft using bearings. The armature is designed to move smoothly relative to the rotor and the bearing provides frictionless movement between them.

The video shows you how an armature of electric motors works in electrical science and engineering. You will also learn many things about an electromechanical components.

Different Parts of DC Motor Armature

An armature has several components consisting of a core, winding, commutator, and shaft. We have tried to show and discuss each of the parts from a basic diagram of motor armature–

Different Parts of DC Motor Armature


A stator is the main non-moving body part of a motor that ensures support and protection for the motor. It comes with a rotating magnetic field to drive the armature rotor. Being a static part of the motor it includes the field windings and electrical power supply along with a terminal.


It’s a moving or dynamic part of a DC motor that’s responsible for the mechanical rotation of the unit. A rotor is made of multiple disks(insulated formant) in a form of laminated sheets.

Which prevents the large eddy current without interfering motor’s regular operation. It also refers to an electromagnetic system that causes interaction between the magnetic field and windings of the armature. Later, that produces torque around the rotor area.


A Yoke is a cast-iron made magnetic frame and another important unit of a DC motor. This frame around the magnet work as a protective cover to make sure inter parts are safe and perform. It also contains magnetic poles and field windings for a continuing motor spin.

Poles(south pole & north pole)

The magnetic poles remain in the wall of a yoke having two parts such as a pole view and a pole shoe. They stay balanced because there are hydraulic pressure and screw for the attachment. Thus, poles reduce the loss of reluctance.

Armature windings

This is another winding part of a DC called motor armature windings having two constructions. You might be familiar with their types, they’re Lap Winding and Wave Winding. Its main job is to alter the magnetic field in a parallel path that mitigates magnetic rotation losses. You’ll also find a low-hysteresis silicon steel lamination there.

Field windings

They’re made of copper wires or field coils and stay around the slot using pole shoes. It’s a form of electromagnetic field flux production in which the rotor armature rotates inside it.


A commutator makes sure the torque acting properly in the armature is going in an identical direction. It’s also a significant part of a DC motor that generates voltage to alternate an armature properly.

Applications of The Armature-Based Electric Motors

You’ll see a number of applications and uses of an electric DC motor, especially the brush one. The reason could be its surge torque as compared to the induction motors. Other benefits of them include easy-to-miniaturize, rational control, and excellent efficiency.

Besides, they come with a great lifespan due to brush wear that causes also noiseless operation. We have provided a list of some use cases:

Electric Vehicles

Many electric vehicles use DC and brushless motors which include hybrid electric cars and motorized electric bikes. The windshield wiper, CD player, and external fan uses brushless dc motors since they’re easy to maintain and whisper. Now, they are used in home appliances.

Electric Vehicles

Here are the names of some electric motors used in vehicles:

  • DC series motors
  • Brushless DC motors
  • 3-phase AC induction motos
  • PMS(permanent magnet synchronous) motors, and more.

Alternatively, you convert a traditional bike to an electric one with some simple DIYers.

Ceiling Fans

You see the most modern ceiling fans are made of DC motors. It’s extremely popular in today’s world. There are several factors that work behind using one, including less power consumption, rapid start-up, and low noise. Whereas conventional ceiling fans used to go for single-phase induction motors.

Other Uses

Apart from ceiling fans and electric vehicles, we can see them in our surroundings. For example– pump drives, cranes machine, conveyor systems, and diesel-electric locomotive technologies. An elevator and electric generator use DC brush motors as well. Though, there are many types of electric motors for bikes and cars.

Benefits of Electric Motors

  1. Environment-friendly operation. Electric motors emit almost no fossil fuel into the environment. So, it’s good news to face the challenges of global warming.
  2. Low power consumption. Therefore, you have nothing to worry about brake your savings.
  3. Easy to maintain. Yes, you can easily fix an electric motor when shows trouble.
  4. Noiseless operation. Unlike other fuel-based engines, the e-motor generates very lower noise as compared to fuel-driven machines.

So, these are the ways in which would ultimately cause the armature in an electric motor to spin forward. They convert electrical energy into mechanical energy using various moving and non-moving mechanical elements. After main assembles and design we found them in form of devices and machines around us.
