Why motor has large winding in shunt resistance than armature resistance?
A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.
What is slotted armature?
A slotted armature is a component of an electric motor or generator that features slots or grooves cut into its core. These slots house the windings of the armature, allowing for efficient placement of coils and enhancing magnetic interaction when the armature rotates within a magnetic field. This design improves the motor's performance by optimizing the electromagnetic forces generated during operation. Slotted armatures are commonly used in various types of rotating machines, including DC motors and AC generators.
Where the armature winding coil placed?
The armature winding coil is typically placed on the rotor of an electrical machine, such as a motor or generator. In a rotating machine, the armature winding is situated on the core, which is often made of laminated iron to reduce eddy current losses. In some designs, such as in certain types of generators, the armature can also be located on the stator. The placement of the armature winding is crucial for the efficient generation of magnetic fields and the conversion of electrical energy.
How the generator and motor works ALTERNATING CURRENT GENERATORS BASIC AC GENERATORS Regardless of size all electrical generators whether dc or ac depend upon the principle of magneticinduction.?
An emf is induced in a coil as a result of (1) a coil cutting through a magnetic field, or (2) a magnetic field cutting through a coil. As long as there is relative motion between a conductor and amagnetic field, a voltage will be induced in the conductor. That part of a generator that produces the magnetic field is called the field. That part in which the voltage is induced is called the armature. Forrelative motion to take place between the conductor and the magnetic field, all generators must have two mechanical parts - a rotor and a stator. The ROTor is the part that ROTates; the STATor is the part that remains STATionary. In a dc generator, the armature is always the rotor. In alternators, the armature may be either the rotor or stator. ROTATING-ARMATURE ALTERNATORSThe rotating-armature alternator is similar in construction to the dc generator in that the armature rotates in a stationary magnetic field as shown in figure 3-1, view A. In the dc generator, the emf generated in the armature windings is converted from ac to dc by means of the commutator. In the alternator, the generated ac is brought to the load unchanged by means of slip rings. The rotating armature is found only in alternators of low power rating and generally is not used to supply electric power in large quantities.
What is the electomagnet in a motor called?

How do car generators work?
A car generator is a DC motor. If you apply power to a working DC motor, it will turn the armature and produce work. If you turn the armature of a working DC motor, it will produce power. Generators in cars were replaced during the early 1960's with alternators.

A motor with large windings will have greater shunt resistance than armature resistance due to the sheer amount of copper wire it must travel through. The gauge of the wire also plays a part in this process.
What is armature current?
Armature current is the current flowing in a motor's armature. The "armature" is another name for the coil (or coils) of wire which are on the motor's "rotor", which is the part that rotates inside its stator. (The "stator" is the fixed, non-rotating part of the motor.)

What is the difference between motor and alternator?
Both are actually the same in many ways. A regular motor can be used to generate electricity if turned by an outside source(pulley and belt) Example,,,wind generators are basically motors operated by the paddles of the windmill turning the armature of the motor.

Would the motor turn if only the armature were excited?
A motor will turn when only the armature is excited, if there is enough residual magnetism in the field.

What is the function of armature winding of a motor?
Armature is a rotating part of the machine, the coil which wound in the core of that rotating part.
What is torque equation in DC generators?
generally generator is used to generate power whether it is AC or DC . to generate energy it is necessary to rotate armature at constant speed . it can be achieved by motor or any engine.
What are the comparisons between motors and generators?
Electric Motors • The electric motor converts electrical energy into mechanical energy • The shaft of a motor is driven by the magnetic forces developed between the armature and field • Current has to be supplied to the armature winding. • Motors obey Fleming`s Left Hand Rule • Electric Motors Fleming`s Left Hand Rule The Left Hand Rule shows what happens when charged particles enter a magnetic field. Generators • A generator converts mechanical energy into electrical energy. • A shaft attached to the rotor is driven by a mechanical force • Electric current is produced in the armature windings. • Generators obey Fleming's Right Hand Rule • Generators The Right Hand Rule shows how a current-carrying wire generates a magnetic field.
