Frequent question: What are the special features of commercial electric motors?

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 features of commercial electric motors name some devices in which electric motors are used?

1 Answer

  • In commercial electric motors:
  • i. the coil is wound on a soft iron core. This increases the strength of magnetic field, which makes the motor more powerful.
  • ii. the coil contains a large number of turns of insulated copper wire.
  • iii. a powerful electromagnet is used in place of permanent magnet.

What are the components of commercial electric motor?

Construction: The main parts of a commercial electric motor are the electromagnets, armature, split ring commutators, and brushes. The armature coil ABCD consists of a rectangular coil made of insulated copper wire wound on a laminated soft iron core.

What does commercial electric motors do not use?

The combination of soft iron core and coil is called an armature. … 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 is the function of a split ring in an electric motor What are the special features of commercial electric motors?

Role of Split Ring in an Electric Motor

Split ring is used for reversing the direction of current in the coil. For the continuous rotation of the coil in the same direction, the current in the coil must be reversed.

In what ways can a motor be made more powerful?

Motor can be made more powerful by winding the coil on a soft iron core of by increasing the number of turns of the coil.

What is an electric motor with help of Labelled diagram describe the working of a simple electric motor in what ways can a motor be made more powerful?

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.

What are the four parts of a simple electric motor?

The main parts of an electric motor include the stator and rotor, a series of gears or belts, and bearings to reduce friction. DC motors also need a commutator to reverse current direction and keep the motor spinning.
