In commercial electric motors: The coil is wound on a soft cor. This increases the strength of magnetic field, which makes the motor more powerful. The coil contains a large number of turns of insulated copper wire. A powerful electromagnet is used in place of permanent magnet.
What is commercial motor in physics?
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 different types of motors?
Types of Electric Motors
- AC Brushless Motors. AC brushless motors are some of the most popular in motion control. …
- DC Brushed Motors. In a DC brushed motor, brush orientation on the stator determines current flow. …
- DC Brushless Motors. …
- Direct Drive. …
- Linear Motors. …
- Servo Motors. …
- Stepper Motors.
How does a electric motor works?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What kind of appliances use a motor?

Where do we use commercial motors?
A commercial motor vehicle (CMV) is any vehicle used to transport goods or passengers for the profit of an individual or business. Examples of CMVs include pickup trucks, box trucks, semi-trucks, vans, coaches, buses, taxicabs, trailers and travel trailers.
What’s the difference between AC and DC motors?
The most basic difference is the power source. A.C. motors are powered from alternating current (A.C.) while D.C. motors are powered from direct current (D.C.), such as batteries, D.C. power supplies or an AC-to-DC power converter.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
What are the two types of motors?
The electric motor is mainly classified into two types. They are the AC motor and the DC motor. The AC motor takes alternating current as an input, whereas the DC motor takes direct current.
What are the three types of motors?
Basic motors have been classified into three distinct types: AC motor, DC motor, and specialized motors.
Can an electric motor generate electricity?
Converting energy from one form to another is the key to understanding the differences between electric motors and generators. An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.

How do you make an electric motor 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 are 2 household appliances that use an electric motor?
The electric washing machine, invented Alva J. Fisher in 1906, is a common home appliance that makes use of an electric motor. Other home appliances that use electric motors include clothes dryers, vacuum cleaners, fans, air conditioners, refrigerators and freezers.
Why doesn’t an AC motor need a commutator?
In AC induction motor, two windings in stator create a rotating magnetic field, which makes the rotor rotate. So there is no need of supply to rotor and hence no commutator. However, in series motor, available for both AC and DC supply, commutators are used to supply current to rotor windings.
