What is DC motor and its uses?

The term ‘DC motor’ is used to refer to any rotary electrical machine that converts direct current electrical energy into mechanical energy. DC motors can vary in size and power from small motors in toys and appliances to large mechanisms that power vehicles, pull elevators and hoists, and drive steel rolling mills.

What is DC motor used for?

Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills.

What are the uses of a motor?

Motors are used in a wide range of applications, such as fans, power tools, appliances, electric vehicles, and hybrid cars.

What is DC motor and its working?

The DC motor is the motor which converts the direct current into the mechanical work. It works on the principle of Lorentz Law, which states that “the current carrying conductor placed in a magnetic and electric field experience a force”. And that force is the Lorentz force.

What is DC motor and types?

Mainly there are two types of DC Motors. One is Separately Excited DC Motor and other is Self-excited DC Motor. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor. The dc motor converts electrical power into mechanical power.

What is difference between AC and DC?

Alternating Current (AC) is a type of electrical current, in which the direction of the flow of electrons switches back and forth at regular intervals or cycles. … Direct current (DC) is electrical current which flows consistently in one direction.

Is a DC motor a battery?

A DC (Direct Current) Motor is an electric motor that supplies power to machines as it uses electrical energy to perform its main function. … The process begins with an electric current – supplied by a battery or direct source.

What is DC motor Class 10?

D.C. motor can be defined as a machine which converts electrical energy to mechanical energy of rotation based on the principle of magnetic effect of current. … The brushes are used to flow the current induced in the armature to the internal circuit. These are the carbon strips which slide against the split ring.

What is types of motor?

What are motors used for in everyday life?

Electric motors are extremely important in modern-day life. They are used in vacuum cleaners, dishwashers, computer printers, fax machines, video cassette recorders, machine tools, printing presses, automobiles, subway systems, sewage treatment plants, and water pumping stations, to mention only a few applications.

What is the principle of DC?

The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given by Fleming’s Left-hand Rule and its magnitude is given by F = BIL Newton.

What is the difference between AC motor and DC motor?

The most obvious difference is the type of current each motor turns into energy, alternating current in the case of AC motors, and direct current in the case of DC motors. … AC motors are available in single- or three-phase configurations, while DC motors are always single-phase.

What is DC motor with diagram?

2. Here normally permanent magnet is used or electromagnets made up of windings Made of miniature size of permanent magnet
3. It can operate through Self Excitation or Separate Excitation It is usually excited by permanent magnet present.

What are the 4 types of motors?

There are 4 main types of DC motors:

  • Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux. …
  • Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current. …
  • Shunt DC Motors. …
  • Compound DC Motors.

What are the 3 types of DC motors?

There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.

What are drives used for?

A drive is a location (medium) that is capable of storing and reading information that is not easily removed, like a disk or disc. All drives store files and programs used by your computer. For example, when you write a letter in a word processor, the program is loaded from the hard drive.
