Generators typically use an electromagnet, which is created by electricity and a rapidly spinning turbine to produce massive amounts of current . The standard generator contains a group of insulated wire coils in the shape of a cylinder. ... When the magnet spins, it induces a tiny current in each part of the wire coil.
What are the similarities and differences between electric motor and generator?
| Electric Motor Electric Generator | The shaft of the motor is driven by the magnetic force generated between the armature and the field. In electric generators, the shaft is attached to the rotor and is driven by the mechanical force. |

How are electromagnets similar to generators?
Generators are based on the connection between magnetism, motion and electricity. Generators typically use an electromagnet, which is created by electricity and a rapidly spinning turbine to produce massive amounts of current. ... When the magnet spins, it induces a tiny current in each part of the wire coil.
What are examples of electric motors give at least 2 examples?

What is the main difference between motor and generator?
The major difference between Motor and Generator is that a motor converts electrical energy into mechanical energy , whereas the generator does the exact opposite. The motor uses electricity whereas the generator produces electricity.
Which motor is used in tramway?
Dc motor (Ma) and induction motor (Mc) are currently manufactured and used in 105 N tram drive, their parameters are available. Dc motor (Mb), brushless motor (Me) and slip-ring motor (Md) pa- rameters have been determined by analysis.
What are the other examples of generator?
| Generator Type Best Use | Portable Generator Refrigerators, spray gun systems, nail guns | Inverter Generator Car batteries, laptops | Standby Generator Emergency settings, hospital machinery |

What do you think is the role of the electric motor in the materials appliances?
Electric motors impact almost every aspect of modern living. Refrigerators, vacuum cleaners, air conditioners, fans, computer hard drives, automatic car windows, and multitudes of other appliances and devices all use electric motors to convert electrical energy into useful mechanical energy .
What is the basic principle of generator?
Electric generators work on the principle of electromagnetic induction . A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.
Can a generator be used as a motor?
In principle, any electrical generator can also serve as an electric motor , or vice versa. In hybrid vehicles and other lightweight power systems, a “motor–generator” is a single electric machine that can be used as an electric motor or a generator, converting between electrical power and mechanical power.
Why generator efficiency is more than motor?
2. Why generator efficiency is more than motor? Ans- The efficiency of a generator is always greater than that of the motor. It is because the leakage of magnetic flux produces power losses in a motor but the leakage of the flux produced by the field winding in the generator is minimum.
Which drive is used in textile industry?
Applications of Industrial Drive > TEXTILE INDUSTRY: The textile industry requires special types of drives for (i) weaving, and (ii) spinning .
Which motor is used for elevator?
Lifts are preferred by AC slip ring or DC compound motor . In case of single phase installation, the commutator motors are preferred. Variable Frequency drive electronic controls are used in the latest lift designs.
Which braking is not possible in series motor?
Regenerative braking is not possible in a series motor. Explanation: In regenerative braking, the motor acts as a generator. The back emf is more than the terminal voltage in case of regenerative braking.
What are the 2 types of generator?
There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators . While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.
What are four types of electrical generators?
Based on these applications various types of generators include portable generators, inverter generators, standby generators, industrial generators and induction generators . Portable generators are very useful in a variety of applications. They come in varying power configurations suitable for different types of uses.
