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 Commercial Motors?
A commercial motor vehicle (CMV) is any vehicle used to transport goods or passengers for the profit of an individual or business. … Commercial motor vehicles also include exceptionally heavy vehicles and those that carry large numbers of passengers.
How is commercial motor different from DC motor?
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 is the commercial electric motor?
In commercial electric motors: … 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 Class 10?
(A) An electromagnet in place of permanent magnet. (B) Large number of turns of the conducting wire in the current carrying coil. When a current is passed through a coil placed in a magnetic field, the coil experiences a torque in a direction given by Fleming’s left-hand rule. …
Where do we use commercial motors?
Answer: 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.
Why electromagnets are used in commercial motors?
Electromagnets are used instead of a permanent one because electomagnets are more powerful. Electromagnets provide the force that spin the motor. Other than that, an electromagnet can be rapidly manipulated over a wide range by controlling the amount of electric current.
What does commercial electric motor 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 are the principles of electric motor?
The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
What kind of magnets are used in commercial motors?
Which Magnets Are Used in Commercial Motors?
Permanent magnets commonly used in motors include sintered magnets and bonded magnets, like AlNiCo magnets, ferrite magnets, SmCo magnets, neodymium magnets, etc.
- AlNiCo Magnets. …
- Ferrite Magnets. …
- SmCo Magnets. …
- NdFeB Magnets.
What is simple motor?
The simple motor built in class uses a coil that is a temporary electromagnet. This coil gets the force to help create torque from the electrical current supplied by the battery. The donut magnet used in the motor is a permanent magnet, which means it has a north and a south pole that are permanently in place.
What do commercial electric motors use to enhance the power of the motor?
The combination of soft iron core and coil is an armature. 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 is necessary for the motor to work?
Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current.
What is the purpose of commutator?
On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
What is an electromagnet Class 10?
An electromagnet is a temporary magnet which behaves like a magnet when an electric current is passed through the insulated copper wire and loses its magnetism when current is stopped. It has a soft iron piece called the core with an insulated copper wire wound on it.
What is electric motor and its principle and working?
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.
