What is a motor principle?
Principle: An electric motor (dc motor) works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field. a force acts on the conductor as a result of which the conductor begins to move and mechanical energy is obtained.
What is the principle of motor effect?
A current-carrying wire or coil can exert a force on a permanent magnet. This is called the motor effect. The wire could also exert a force on another nearby current-carrying wire or coil.
Which law is used in motor?
Faraday’s law of induction is the fundamental law on which electric motors operate.
What is in a motor?
A simple motor has six parts: an armature or rotor, a commutator, brushes, an axle, a field magnet, and a DC power supply of some kind.
What is the difference between motor effect and generator effect?
The generator effect is when a current is induced in a wire which is experiencing a changing magnetic field while the motor effect is when a current carrying wire’s magnetic field interacts with the magnetic field around it, resulting in a force being exerted on it, causing it to move.
What is the fundamental motor equation?
e(t) = -dφ/dt …( 1) Where Φ represents the flux in the coil. This is one of the fundamental equations used to derive the electrical model of a motor.
Who made Fleming’s left hand rule?
John Ambrose Fleming
Fleming’s Left-Hand Rule is a simple and accurate way to find the direction of force/motion of the conductor in an electric motor when the magnetic field direction and the current direction are known. It was originally developed by John Ambrose Fleming, an English electrical engineer, in the late 19th century.
What is the principle of motor and generator?
The working principle of a motor is based on the current-carrying conductor that experiences a force when it is kept in the magnetic field. The working principle of generator is based on electromagnetic induction.
What is the 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.
What is the fundamental difference between motor and generator?
An electric motor is a machine that converts electrical energy to mechanical energy. An electric generator is a machine that converts mechanical energy to electrical energy.
What is difference between Fleming left and right-hand rule?
Fleming’s left-hand rule gives the direction of magnetic force acting on a conductor whereas Fleming’s right-hand rule is used to find the direction of induced current.
Who gave right hand thumb rule?
In mathematics and physics, the right-hand rule is a common mnemonic for understanding notation conventions for vectors in 3 dimensions. It was invented for use in electromagnetism by British physicist John Ambrose Fleming in the late 19th century.
What is motor control example?
An example of fine motor control is picking up a small item with the index finger (pointer finger or forefinger) and thumb. The opposite of fine motor control is gross (large, general) motor control. An example of gross motor control is waving an arm in greeting.
What is difference between motor and generator?
An electric motor is a machine that converts electrical energy to mechanical energy. An electric generator is a machine that converts mechanical energy to electrical energy. `
