What does the commercial electric motor constitutes?

What is commercial electric motor?

Commercial motors are difference from simple electric motors in the following ways. In commercial motor an electromagnet is used in place of permanent magnet. Commercial motors have more number of turns of conducting wire in current carrying coil. Commercial motors have soft iron core on which the coil is wound.

What are the special features of commercial electric motors?

Special features of commercial electric motors are:

  • The coil is wound on a soft iron core; therefore, the strength of magnetic field increases.
  • The coil contains large number of turns of insulated copper wire.
  • A powerful electromagnet is used in place of permanent magnet.

How is the power of commercial electric motor enhanced?

A commercial electric motor is one which uses the following (i) An electromagnet in place of permanent magnet. … It enhances the power of motor. Thus, commercial electric motors do not use permanent magnet to rotate the armature because permanent magnets are weak and do not produce strong magnetic field in the region.

What’s Inside an Electric Motor?

  • Rotor coil. The coil is made of copper wire, because copper is such an excellent conductor. …
  • Armature. The armature supports the coil and can help make the electromagnet stronger. …
  • Permanent magnets. There are two permanent magnets. …
  • Commutator. …
  • Brushes. …
  • Steel former.

What is the working principle of motor?

The DC motor is the motor which converts the direct current into the mechanical work. It works on the principle of Lorentz Law, which states that “the current carrying conductor placed in a magnetic and electric field experience a force”.

In what ways can a motor be made more powerful?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

What is an electric motor with the help of Labelled diagram describe the working of a simple electric motor?

An electric motor works on the principle of magnetic effect of electric current. In an electric motor, a rectangular coil ABCD in placed between two magnets in poles N and S. Now, current is passed through it continuously. When current is passed into the coil, it produces a magnetic field around it.

Who is an armature?

In electrical engineering, an armature is the component of an electric machine which carries alternating current. … When the machine or motor is used as a motor, this EMF opposes the armature current, and the armature converts electrical power to mechanical power in the form of torque, and transfers it via the shaft.

What is the principle of an electric motor name some of the devices in which electric motor are used?

Answer: An electric motor works on the principle that when a rectangular coil is placed in a magnetic field and current is passing through it, a force acts on the coil which rotates it continuously. Explanation: Electric motors are used in washing machines,mixer and grinder and electric cars.

How do you increase the power of an electric motor?

How can the power of an electric motor be increased explain with any three points?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

In what way these simple electric motor is different from commercial motor?

Difference between simple electric motors and commercial electric motors: In commercial electric motors, field coils are used for producing magnetic fields and not a permanent magnet as in simple electric motors. These coils become magnetized when current is passed through them.

Why are electric motors important?

More than 40% of generated electricity is consumed by industry, and two-thirds of that energy is used by electric motors. By using more efficient motors it would be possible to achieve huge savings in both energy and carbon dioxide emissions.

Do electric cars need oil changes?

Any need for engine pistons, valves, and other moving parts that need to be lubricated, electric vehicle does not need regular oil changes. Electric cars use completely different drivetrains, so you will never have to worry about routine oil changes that are necessary for traditional cars.
