Most don't; some do!
Most televisions have no motor; the picture display is controlled entirely electronically. But some earlier rear-projection, large-screen, CRT TVs did use a rotating color wheel, timed with light pulses, to display colors. And the color wheel is used in one of the very newest technologies, the DLP system, in single-chip DLP projectors. These TVs do have an electric motor to spin that color wheel.
You might think that older CRT (tube-type) televisions might use a motor-driven fan for cooling, but they rely only on venting and convection to keep components from overheating.
What else can I help you with?
What changes electric energy into motion?
Electric energy is converted into motion through an electric motor. The electric motor uses electromagnetism to create a magnetic field that interacts with electrical currents, producing a rotational motion. This motion can then be used to power various devices and machinery.
When did Michael Faraday come up with the electric motor?
The Electric motor was invented in 1821 by Michael Faraday.
What tasks could an electric circuit accomplish?
Heat a kettle, light a room, produce a tv picture, run a computer or a laptop or a mobile phone or a radio. Run air conditioning and heating. Run a drill, including a dentist's drill or any other electric motor. Control an engine on a ship or aircraft. Start a car.
What size hydraulic motor is needed to be equal to a 3 hp electric motor?
To determine the size of the hydraulic motor needed to be equal to a 3 hp electric motor, you would need to calculate the hydraulic motor's power output in horsepower. Hydraulic motors are generally less efficient than electric motors, so you may need a larger hydraulic motor to match the power output of a 3 hp electric motor. Consult the manufacturer's specifications and consider factors such as efficiency and operating conditions.
Electric motor was invented by zenobe gramme or Michael Faraday?
The electric motor was invented by Michael Faraday. Gramme invented the Gramme dynamo, which was a type of electric generator that helped advance the development of electric motors.
What energy transformation takes place using appliances?
electric fan motor cycle washing machine electric stove television set
What is the function of an electric motor in terms of electric power and motor?
The electric motor changes electric energy into mechanical energy.
Which conversion does an electric motor make?
electric energy to mechanical energy
Why it is that mechanical energy is the output of an electric motor?
Because that is the purpose on an electric motor.
What is a machine that turns mechanical energy into electrical energy?
Electric motor.
What changes electric energy into motion?
Electric energy is converted into motion through an electric motor. The electric motor uses electromagnetism to create a magnetic field that interacts with electrical currents, producing a rotational motion. This motion can then be used to power various devices and machinery.
What is the output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
What can be powered by an electric motor?
An electric motor can power anything that needs mechanical torque.
What is output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
What electric motor?
A electric motor is a device that converts electrical energy into mechanical energy.
What is the voltage tolerance of a standard electric motor?
the voltage tolerance of a standard electric motor is
The current in an electric motor comes from?
Power plants (fueled by elements) produce the electrical energy that circuits to an outlet that you can charge an electric motor with a plug that is wired to an electric motor. Or if it is a vehicle with an electric motor, you electrically charge car batteries that produce the current to the electric motor.
