3. Is there a difference between the structure of an electric motor and a generator? What are some differences, if
any?
4. How is the principle of electromagnetic induction applied
Answers
Answer:
1.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.
2.An Electric generator is a device which is used to produce electric energy, which can be stored in batteries or can be directly supplied to the homes, shops, offices, etc. Electric generators work on the principle of electromagnetic
3.The Difference between Motor and Generator are as follows:-.
The Motor converts electric energy into mechanical energy, whereas generator does the opposite.
Electricity is used in the motor, but the generator produces the electricity.
The Shaft of the motor is driven by the magnetic force developed between armature and field windings whereas, in the case of the Generator the Shaft is attached to the rotor and is driven by mechanical force.
The current is to be supplied to the armature windings in case of a Motor, and in Generator, current is produced in the armature windings.
Motor follows Fleming’s Left hand rule while Generator follows Fleming’s Right hand rule.
The example of Motor is an electric car or bike where electric current is supplied to the machine or device, and it gets converted into mechanical motion and, as a result, the car or bike moves. The example of Generator is that in power stations the turbine is used as a device which converts mechanical energy of force of water falling from the dam to generate electric energy.
4.Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.
hope this helps you .
