Will a DC motor actually produce voltage if it is spun in reverse?
AnswerIt'll produce voltage if you spin it forwards, too. The only difference between a DC motor and a DC generator is what you use it for.A long time ago, cars had DC generators on them instead of AC alternators. When you replaced a generator, you had to "polarize" it so it would make electricity. You hooked it up to your battery and let it run, as a motor, for a few seconds. Don't try that with an alternator because you'll break it.If you're looking for a neat little elementary-school science project, you can use little Radio Shack electric motors as generators for things like windmills, water wheels, dynamos turned by bicycle tires...Actually, yesA motor works by passing current through the conductors of an electromagnet (the rotor or armature) suspended in the magnetic field of a permanent magnet (or another electromagnet). The rotor is the moving part, that is, the part that spins. If instead of energizing the rotor's windings, you turned the rotor by hand, you would indeed induce a current in the rotor's windings. Basically you have created a generator.Motors work on the basic principle of a current going through a conductor producing a magnetic field around the conductor. If you reverse that you have a magnetic field around a conductor which produces current.

What does the brushes and commentator in a D C motor do?
i have never heard of a commentator in a motor, think you may be mistaking that word. inside an electric motor you have a stator and windings, as polarity changes it spins the stator and the brushes transfer the charge to the device being used.. I think they meant commutator. If you break an electric motor down to 2 parts, you have a commutator and an armature. the armature being the shaft that basically floats on bearings, and the commutator being the hull where the stator is. (and there is such thing as a brushless electric motor.) the stator does not spin. that is the term used for the magnets that pull the electric field supplied by the brushes. To make even more simple, imagine a shaft floating on bearings with 2 magnets on it, one positive and one negative ( the armature) and this shaft is inside of a ring of electricity the is flowing in one direction, its going to pull the negative and push the positive (the commutator) and cause the armature to spin.
What are the parts of a dynamo?
Electric motor, the alternating-current alternator, and the rotary converter. A basic dynamo consists of a stator wound with copper coils and a magnetic armature. As the magnetic armature spins it induces a current in the copper coils.
What part of motor makes the current in the coil reverse every half turn so that motor spins continuously?
The direction of the current flowing through it must be changed after every half rotation. Otherwise, when the north pole of the coil comes near the south pole of the magnet, there will be attraction between them and the coil will stop rotating.
How much does a 1996 Rolls-Royce cost?
the rotor is the part that spins inside the alternator (like the armature in an electric motor) current is fed into it creating electromagnetism, the stator, the other part of the alternator which surrounds the rotar is also fed with current and also becomes a series of electromagnets. When these are both fed and the rotor is turning inside the stator a high magnetic field is created between the two parts being....electricity!
How do i know that they have electromagnet in the motor?
because it will contain a magnet inside that spins with copper windings like a car alternator
What houses magnets and a spinning coil of copper?
An electric motor. In a motor the coil spins within the magenetic field producing mechanical energy. In a generator the magnet spins within a coil to produce electricity. in either case the magnets can be either solid fixed magents or electromagnetic coils.
What houses magnets and coil and copper wire?
An electric motor. In a motor the coil spins within the magenetic field producing mechanical energy. In a generator the magnet spins within a coil to produce electricity. in either case the magnets can be either solid fixed magents or electromagnetic coils.
Magnet that spins on its axle in a motor?
The rotation of the magnet within a motor generates a changing magnetic field, inducing an electric current in nearby wire coils according to Faraday's law of electromagnetic induction. This current creates a magnetic field that interacts with the rotating magnet, causing torque that drives the motor's rotation. By continuously alternating the direction of the current flow, the magnet's spins are synchronized with the changing magnetic fields to maintain rotation.
How do you know if a fan clutch is standard or reverse spin?
crank the motor over and watch which way the fan spins. If your standing in front of the motor and and spins clockwise (to the right) its standard. If it spins counter clockwise(to the left) its reverse.
What name is given to the fan-like device that spins in a generator?
The fan-like device that spins in a generator is called a rotor or an armature. This component is essential in converting mechanical energy into electrical energy within the generator.
What does does an electrical motor use to create motion?
An electric motor uses electromagnetic fields to convert electrical energy into mechanical motion. This is achieved by the interaction between the magnetic field generated by the motor's stator and the current flowing through its rotor. This interaction produces a force that spins the rotor and drives the motion of the motor.
What is the difference between alternator and generator and what do you use in power plants mostly and why?
The term, 'generator', can be applied to both A.C. and D.C. machines. An 'alternator' is specifically an A.C. generator. Power stations use alternators, because it is necessary to transmit electrical energy at high voltages, and this is done using transformers, which are A.C. machinesmain difference depends on magnetic field spin or fixed..."In an alternator, electricity is produced when a magnetic field spins inside the stator. In generator, the armature or windings of wire spin inside a fixed magnetic field to generate electricity"alternator use on smallscale production & generator use on large scale..
