Common questions

How many conductors are in a turn?

How many conductors are in a turn?

Turn: A turn consists of two conductors connected to one end by an end connector.

What is conductor in armature?

4.15) the armature conductors are formed as a thin-walled cylinder consisting essentially of nothing more than varnished wires wound in skewed form together with the disc-type commutator (not shown).

How do you calculate armature conductor?

Total number of conductors of armature winding (Z)= 150 × 8= 1200. Number of turns = 1200/2= 600. a S ( ) . generator (voltage across the brushes of different polarity) = sum of the EMFs of all the conductors connected in series in one parallel path.

What is the difference between conductor and coil?

A conductor is just the wire itself. A coil is one or more loops of conductor formed to concentrate magnetic flux linkages.

What is turn in electrical engineering?

A single turn/coil has two active sides, or otherwise called as conductors. Similarly, a two turn coil has four conductors and a three turn coil has 6 conductors.

What is coil and turn?

coil, in an electric circuit, one or more turns, usually roughly circular or cylindrical, of current-carrying wire designed to produce a magnetic field or to provide electrical resistance or inductance; in the latter case, a coil is also called a choke coil (see also inductance).

What factors determine the force exerted by a conductor on the armature of a DC motor?

The force that is developed on a conductor of a motor armature is due to the combined action of the magnetic fields. The force developed is directly proportional to the strength of the main field flux and the strength of the field around the armature conductor.

How many conductors are in a slot?

Defines how many conductors that are placed in one slot. The number of conductors per slot must be an integer that is equal or greater than one. In addition, the number of conductors per slot must be a multiple of two for a double-layer winding, refer to Fig.

Which factor determines the difference between the types of armature windings?

2. Which factor determines the difference between the types of armature windings? Explanation: The armature windings are all connected to the commutator in the case of DC machines. Commutator is nothing but device which converts dc voltage to ac voltage.

What is the relation between conductor current and armature current in wave winding?

What is the relation between conductor current and armature current in wave winding? Explanation: the number of parallel paths in the in a wave winding is equal to 2. So, armature current will get divided equally into total number of conductors/paths. Conductor current in a wave wounded machine is half of the Ia.

Does transformer change power?

Transformers change the voltage of the electrical signal coming out of the power plant, usually increasing (also known as “stepping up”) the voltage. Transformers also reduce (“step down”) the voltage in substations, and as distribution transformers.

How does armature rotate?

The armature is mounted on bearings and is free to rotate. It is mounted in the magnetic field produced by permanent magnets or current passing through coils of wire, which are called the field coils. When a current passes through the armature coil, forces act on the coil and result in rotation.

What is the difference between armature turns and conductor size?

The armature turns will decide the amount of magnetic flux that can be produced while the conductor size will determine how many will fit in the armature slots…Both will determine the amount of magnetic lines of force and the strength of the magnetic flux that will be developed… A combination of amperage and voltage put together in a magnet form..

What is the armature of an electric machine?

The armature of an electric machine is the name historically given to the winding where a voltage is induced and power transfer between electrical and mechanical systems occurs. It is a term used in dc machines and ac synchronous machines. In a dc machine, the armature is the rotating circuit. Commutation

What is the armature of a DC motor?

DC Armature The armature of an electric machine is the name historically given to the winding where a voltage is induced and power transfer between electrical and mechanical systems occurs. It is a term used in dc machines and ac synchronous machines. In a dc machine, the armature is the rotating circuit.

What is armature winding in a DC machine?

The winding in the machine where the voltage is induced is called an armaturewinding. In a dc machine, the armature winding is the winding on the rotor. Defining the DC machine constant \\(k\\):
