What is a function of a motor?
An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. … This force creates a torque on a loop of wire present in the magnetic field, which causes the motor to spin and perform useful work.
What is the function of AC 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 known for their increased power output and efficiency, while DC motors are prized for their speed control and output range.
What are the function of each part of motor?
Armature Core: Holds the armature coil in place and provides mechanical support. Armature Coil: It helps the motor to run. Brushes: It is a device that conducts current between stationary wires and moving parts, most commonly the rotating shaft.
What is the function of AC motor *?
The AC Motor is used in the conversion of electrical energy into mechanical energy. This mechanical energy is made from utilizing the force that is exerted by the rotating magnetic fields produced by the alternating current that flows through its coils.
What is the advantage of DC motors over AC motors?
DC motors have the advantage of: higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and they are easier and cheaper to control than AC. AC motor advantages include: lower power demand on start and minimal maintenance.
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.
What is the difference between electric motor and DC motor?
An electromechanical machine that converts the electrical energy into mechanical energy is called an electric motor. … 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 is the main part of motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.
What are 3 main parts of a motor?
No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin.
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 DC motor applications?
DC machines are also used in applications where high starting torque and accurate speed control over a wide range are important. Major applications for DC motors are: elevators, steel mills, rolling mills, locomotives, and excavators. Like other rotating machines, DC motors result from the interaction of two magnets.
