Why use capictor in motor?
To create rotating magnetic field inside motor stator and it is done by capacitor. current drawn by motor running winding is lagging in nature when capacitor is connected in series with starting winding then the phase angle of running winding current and starting winding currents changes which creates a rotating magnetic field and motor is able to run.
Why does the rotation of the motor reversed when change the polarity across the main winding coil?
When changing the auxilary face winding connection the current flow in the winding is changed so that the rotating emf direction is changed . Thats why the motor rotates in opposite direction.
Do induction motors work on the transformer principle?
Didn't work.because primary and secondary winding not in motorAnswerYes. The rotor behaves as a rotating secondary winding -i.e. there is no electrical connection between the field windings and the rotor.
What is The stationary winding assembly in an alternator called?
The stationary winding assembly in an alternator is called the stator. It consists of multiple coils of wire wound around a core, which generates alternating current (AC) when the rotor, a rotating magnetic field, passes by it. The stator is essential for the conversion of mechanical energy into electrical energy in the alternator.
What is the difference between a field winding and an armature winding in any machine?
In electrical machines such as motors and generators, the field winding is responsible for producing a magnetic field within the machine. This magnetic field interacts with the armature winding, which carries the electric current and generates mechanical power. The field winding typically has fewer turns of thicker wire compared to the armature winding, which has more turns of thinner wire to handle higher currents.
What is field winding?
The field winding on a generator is the winding that is electrified to create an electromagnet; it is generally the winding found on the rotor (the rotating part of the generator).
What are the release dates for Coil Winding Machines - 1904?
Coil Winding Machines - 1904 was released on: USA: May 1904
Induction Motor working principle?
An induction motor works on the principle of electromagnetic induction. When an alternating current flows through the stator windings, it creates a rotating magnetic field. This magnetic field induces a current in the rotor windings, causing it to rotate and drive the attached load.
What is primary induction?
Primary induction refers to the initial phase in the process of electrical generation, particularly in electrical machines like generators and transformers, where an alternating current (AC) is induced in the primary winding. This induction occurs due to the changing magnetic field created by the current flowing through the primary coil, which then produces a magnetic flux that induces an electromotive force (EMF) in the secondary winding. The principle is based on Faraday's law of electromagnetic induction, which states that a change in magnetic flux can generate an electric current.
Why alternators constructed with stationary Ac winding and rotating pole?
To eliminate the requirement for slip rings and brushes to handle the large voltage/current involved.
The old welding machines used electromagnetic winding to step up the current for welding rods. What is the new principle inside the welding machines?
The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.
What are the uses for a coil winding machine?
winding machine is used to wind the string, wire, cable, thread, rope, etc onto a spool or bobbin. They are of various types from simple winding machines to complex programmable winding machines like CNC winding machines. Mostly winding machines are used in textile, and paper industries, to quickly wrap a large amount of string or paper onto a spool. These winding machines are used by small to large businesses according to the winding needs.
