Working Principle of DC Motor (animation of elementary model)

by admin February 6, 2019

Please support us on PATREON and help chrvoje engineering channel be sustainable
https://www.patreon.com/chrvojeengineering

Working Principle of DC Motor

Working principle of D.C. motor is very simple. We can see that when the current conductor is placed in magnetic field, it experiences some force in particularly direction (picture 1.1).

Conductor placed in magnetic field

picture 1.1: Conductor placed in magnetic field

The very basic construction of a D.C. motor contains a current carrying armature which is connected to the supply and through commutator segments and brushes. the armature is placed between north and south pole of a permit or an electromagnet in elementary model. One single turn of conductor is placed between two opposite poles if we start to supply D.C. via commutators system current will start to flow (picture 1.2).

Basic construction of a DC motor

picture 1.2: Basic construction of a DC motor

As we see positive terminal of a battery is connected to left conductor of a turn and a negative terminal is connected to right conductor of a turn. As we see in model north pole of the magnet is placed near left side and south pole is placed near right side of the turn (picture 1.3).

picture 1.3: Connection of battery and conductor with magnetic poles near

Current in left side flows inward and current in the right side flows outward as we see conductor is carrying current and they placed in magnetic field both of them experienced a mechanical force acted on them. Direction of mechanical force can be easily determined by applying Fleming’s left hand rule (picture 1.3) .

Fleming’s left-hand rule

To do this spread out your left thumb and forefinger and second finger so they are all at ninety degrees to one another (picture 1.4).

Fleming’s left-hand rule picture 1.4: Fleming’s left hand rule

With that if the forefinger is align along direction of magnetic field from the North Pole to the South Pole and second finger is align along direction of the current in left side conductor then thumb indicates direction of mechanical force.
(picture 1.5).

picture 1.5: Direction of Thumb finger or mechanical force

Similarly if the fore finger is align along the direction of magnetic field from the North Pole to the South Pole and second finger is align along direction of the current in a right side conductor then thumb indicates direction of mechanical force due to this upward and downward forces on the turn (picture 1.6).

picture 1.6: Direction of Thumb finger or mechanical force

One torque is produced when turn rotates on clockwise direction as shown (picture 1.7) .

One torque is produced when turn rotates on clockwise direction as shown.

picture 1.7: One torque is produced when turn rotates on clockwise direction

After rotation of the Turn, turn comes to vertical position in respect of the magnetic field (picture 1.8).

Turn comes to vertical position in respect of the magnetic field.

picture 1.8: Turn comes to vertical position in respect of the magnetic field.

At this position there is no current in conductor because the turn conductor and brushes rest between two commutators. Hence there is no force acting on conductor by due to moment of inertia, turn continue to rotate and comes horizontal again, position of conductor has been changed, here that means conductor which was previously in left position comes to right position and which was previously in the right position comes to left position. At that position we can determine mechanical force with applying Fleming’s left hand rule let’s do that to do this spread out your left thumb, forefinger and second finger so they are all at ninety degrees to one to another. So if forefinger is align in direction of magnetic field. That is from the North Pole to South Pole and second finger is aligned in direction of a current in the left side conductor then thumb indicates direction of mechanical force this is clearly upward here (picture 1.9).

How to determine mechanical force with applying Fleming's left hand rule when conductor and brushes rest between two commutators

picture 1.9:How to determine mechanical force with applying Fleming’s left hand rule when conductor and brushes rest between two commutators

So if forefinger is align in direction of magnetic field that is from the North Pole to South Pole and second finger is aligned in the direction of a current in the right side conductor then from indicates direction of mechanical force this is clearly downward here. Do this upward and downward forces turn tends to rotate in clockwise direction from that explanation we can come to a conclusion that here in this model we can see that whichever conductor comes near South Pole experience upward mechanical force and near North Pole downward mechanical force. And do this continuously forces mechanical turn rotate even if battery is not connected particularly D.C. motor rotates at the same principle like this elementary model instead of single turn in D.C. motor we have mount turns on major coil and instead of two poles there is number of Poles installed.

How to Wire Contactor and Motor Protection Switch – Direct OnLine Starter (DOL) – Explanation

by admin February 2, 2019

Please support us on PATREON and help chrvoje engineering channel be sustainable
https://www.patreon.com/chrvojeengineering

How to Wire Contactor and Motor Protection Switch – Direct OnLine Starter (DOL)

The direct online motor starter is the cheapest and simple construction to start the induction motor. DOL motor starter is not limiting the starting current and its directly start the motor. The Direct On Line Motor Starter (DOL) consist of start and stop control switches , contactor, motor protection switch and miniature circuit breaker.

Connection diagram of Direct OnLine Starter

Connecting of Direct OnLine starter

Power supply is connected to (NO) Normally open contacts (1,3,5) of motor protection switch,

Contacts (2,4,6) of motor protection switch are connected to (NO) Normally open contacts (1,3,5) of contactor, also START push button is connected to a A1 terminal of magnetic coil of contactor. Normally open contact (NO) (13) of contactor is also connected to A1 terminal of magnetic coil of the same contactor.
Contacts (2,4,6) of contactor are connected to electric motor. Stop push button (1) is connected on contacts of START
push button (2) and contact (14) of contractor.
Control circuit is connected in a way that power supply is connected on Miniature Circuit Breaker (MCB) (1) from Miniature Circuit Breaker (2)to a STOP push Button (2) and from that (1) to a START push button (2).

Working principle of Direct OnLine Starter (DOL)

Most important is control circuit, control circuit works on a principle of self-reliance. Self-reliance is way that current is always present on contact (2) of START push button and contact (14) of contactor. So when we press START push button current goes toward terminal A1 of contractor. Magnetic coil is energized in contactor and contactor closes all contacts.
Also current is coming on terminal A1, from another way, from contact (1) of STOP push button over contacts (13 and 14) ,which are now closed, of contactor. So, when we release START push button current constantly coming to a terminal A1 from contact (1) of STOP push button over contacts (13 and 14) ,which are now closed, of contactor. A2 terminal of contactor is connected on null wire. In this way electric motor starts to work.
If we want to stop electric motor to work, then we must press STOP push button, current will no longer flow over contacts (13 and 14) of contactor, magnetic coil of contactor will not be energized, contactor will release contacts (1/2, 3/4,5/6) and electric motor will stop to work.

Advantages and disadvantages

Direct OnLine Starter is the most common starting method available on the market. The starting equipment
consists of only a main contactor and thermal or electronic overload relay. The disadvantage with
this method is that it gives the highest possible starting current. A normal value is between 6 to 7
times the rated motor current but values of up to 9 or 10 times the rated current exist. Besides the
starting current there also exists a current peak that can rise up to 14 times the rated current since the motor is not energised from the the first moment when starting.The values are dependent on the design and size of the motor, but in general, a smaller motor gives higher values than a larger one. During a direct-on-line start, the starting torque is also very high, and is higher than necessary for most applications. The torque is the same as the force, and an unnecessary high force gives unnecessary high stresses on couplings and the driven application. Naturally, there are cases where this starting method works perfectly and in some cases also the only starting method that works.

Alternator, How it works?

by admin February 2, 2019

Please support us on PATREON and help chrvoje engineering channel be sustainable
https://www.patreon.com/chrvojeengineering

How does an Alternator Work?
Alternator An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. Electricity is produced in alternators by electromagnetic induction. The way the alternator generates electricity is from two types of alternator.
Types of Alternator
Type – 1 Type one is rotating magnetic field with a stationary armature. Type – 2 Type 2 is a rotating armature with a stationary magnetic field. Most alternators use are rotating magnetic field with a stationary armature.
Alternator Construction
Main parts of alternator are rotor, stator, bearing, slip ring, regulator, D.C. generator, pulley and outer cover.
How does an alternator work?
Rotor produces a rotating magnetic field, armature coils are stationary and rotating magnetic flux associated with the rotor induces electricity in the armature coils. Kind of rotor shown here is known as salient pole rotor. For gaining better insight of its working let’s consider a rotor with just four poles. Rotor coils are excited with a D.C. power source. The rotor is made to rotate by a prime mover, this makes that rotor flux also rotate along with it, at the same speed. Such revolving magnetic flux now intersects the armature coils which is fitted around the rotor. Magnetic flux will generate an alternating electromagnetic force across the winding. Since four pole rotor has got two pairs of north and south poles, so when the rotor turns a half revolution the induced E.M. F. Takes one complete cycle so it is clear that frequency of the induced E.M.F. is directly proportional to the number of Poles in rotor speed It can be easily established that frequency of induced E.M.F. rotor speed and number of Poles are connected through the following relationship. f(Hz), N(rpm), P f = PN/120 It is clear from this relationship that frequency of electricity produced is synchronized with mechanical rotational speed. For producing three phase AC current two more such armature coils which are in one hundred twenty degree phase difference are star connected. Also It is clear from past equation that in order to produce 60 hertz electricity a four pole rotor should run at following speed of 1800 rpm. Such huge R.P.M. Will induce a tremendous centrifugal force on poles of the rotor and it may fail mechanically over time. f = PN/120, 1800 rpm Generally having ten to forty poles which demands lower rpm. Used when the prime mover rotates at relatively lower speed from 120 to 400 rpm. Pole core Is used to effectively transfer magnetic flux and they are made with fairly thick steel lamina. Such insulated lamina The reduces energy loss due to any current formation. D.C. current is supplied rotor with a pair of slip rings. This is the reason why rotating magnetic field approaches used an alternator. If rotating coil method were used slip rings have to fit it along with the armature coils in order to collect electricity but transferring such high voltage electricity with sliprings rather impractical it is quite possible to transfer low voltage D.C. excite current with slip rings. This D.C. current is supplied either from an external source or from a small D.C. generator which is fitted on the same prime mover such alternators are called self excited. With variation of load generator terminal output voltage will vary it is desired to keep the terminal voltage in a specified limit automatic voltage regulator help seen achieving this voltage regulation can be easily achieved by controlling the field current. Terminal voltages below the desired limiter regulator increases the field current this will result with increasing terminal voltage if terminal voltages are below the specified limit the reverse is done.
