Our technical department is cool as always soΒ we are here again with our new short post about PMDC Motor.
Don’t procrastinate – read it π
We already wrote about Flemming’s left hand rule, but perhaps, there are new readers who didn’t read our previous post, so we’ll shortly explain it again.
Flemming’s left hand rule– this rule is applicable for d.c motors. The rule states that, whenever a current carrying conductor is placed in a magnetic field, a force acts on the conduct in the direction perpendicular to both, the current and the magnetic field.
Since all D.C motors work on Flemmingβs left hand rule, it’s essential to establish a magnetic field.
This magnetic field is produced by the means of magnets.
When permanent magnets are used to create the magnetic field, the motor is called a Permanent Magnet motor or aΒ PMDC motor.
Construction of PMDC Motor:
STATORΒ – is a steel cylinder with permanent magnets placed at the inner periphery of the steel cylinder.
The magnets are placed so that the alternate poles of the magnets are facing the armature or the rotor (i.e if the north pole of one magnet is facing the rotor, the south pole of the next magnet will be facing the rotor).
ROTOR- is made of varnish insulated, slotted circular laminated steel sheet. The rotor consists of core, winding and commutator.
Carbon or graphite brushes are places with spring pressure on the commutator segments to supply current to the rotor.
Working principle of the PMDC Motor:
As mentioned earlier, the D.C motor works on Flemmingβs left-hand rule, when the current carry conductor comes inside a magnetic field, it experiences a mechanical force which is governed by the left-hand rule.
The armature/ rotor is placed in the magnetic field of the permanent magnet(i.e the stator); the armature rotates in the direction of the generated force.
The conductors on the armature experiences the mechanical force of F = B.I.L Newton, where
B =Β magnetic field in tesla;
I = current in Amperes;
L = length of the conductor in meters;
Each conductor experiences forces and the compilation of these forces result in torque, because of which the armature rotates.

Disadvantages of PMDC Motor:
Applications of PMDC Motor:

In the 1st part of our BLDC Motor Basics post we promisedΒ you to provide information about the BLDC motor principle of work,Β about improving the performance of it and the BLDC motor types. We appreciate our readers and we keep our promises, so here it is – read, learn and enjoy π
WorkingΒ principle:Β basic interaction between a permanent magnet(rotor) and an electromagnet(stator).
For simplicity,
Consider three stator coil winding arrangements A, B and C.
When coil A is given a dc supply, it gets energized and becomes an electromagnet.
The opposite pole of the rotor gets attracted to the stator(opposite poles attract). As a result, the rotor pole moves near the energized stator.
As the rotor nears the coil A, coil B of the stator is energized. Similarly, as the rotor nears coil B, coil C is energized. After that, coil A is energized with opposite polarity.
This process is repeated, and the rotor continues to rotate.
Improving the performance of the BLDC motor:
Problem – Β as seen above, only one coil is energized at an instant. The 2 inactive coils greatly reduce the power output of the motor.
In order to avoid that, energize coil B with the same polarity as coil A, when the rotor is in the position with coil A.
In this way, the combined effect will push the rotorΒ and produce more torque and power output from the motor. The combined force also makes sure that a BLDC has a beautiful, constant torque nature.
To energize the 2 coils at the same time, the free ends of the coils are connected together.
Electronic controller unit:
An ECU is used in a BLDC motor to determine the position of the rotor and to energize the coils accordingly.
The Hall-effect sensor is used to sense the position of the rotor.
This sensor gives information to the controller, which energizes the stator coils accordingly.
Types of BLDC Motor:
1.Out-Runner:
In the Out-Runner type, the magnets are placed on the outside of the stator, as shown in the fig. below.
Compared to the in-runner type bldc motor, the out-runner has more mechanical advantages.It has comparatively more torque.
Comparatively, It can swing heavier props.
Β 2. In-Runner:
In the In-Runner type of motor, the magnets are placed on the inside of the stator, as shown in the fig. below.
Comparatively, it runs on high RMP.
Advantages of a BLDC motor:
Applications of BLDC Motor:

Monday Greetings from GoGoA1.com team,
Our first post will be of magnesium alloy wheels. In recent years, magnesium alloy has attracted wide attention from all over the world, as the most promising lightweight material for key researchers, and developed a series of technology to promote the magnesium alloy in the transport, aerospace and defense industry applications. Despite this, many people are still not aware or are confused about bicycle wheels that are made of magnesium alloy.GoGoA1.com wants to conduct an educational program and to give answers on all of the existing questions about magnesium alloy and wheels.
So letβs think what magnesium alloy is and why that material is excellent for bicycle wheels?
