The Pros And Cons Of A Brushless Motor

Physics Internal Assessment 2.2

Introduction for this assessment we have to have to find the difference between a certain amount of motors and also have to find out what made them so different between each other. We are trying to find out the physics of motors between a brushed and brushless motor.

Motors

How motors work motors convert electric energy to mechanical motion.

For electrical motors, it can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. The direction of the current must be reversed every half turn, otherwise the coil comes to a halt again.`

The Physics of a motor effect

This is known as the fleming left hand rule, this rule is used when you would want to work out the

The coils are used, one phase after the other, by the electronic speed controller as cued by the signals from the rotor position sensors.

Advantage and Disadvantage of a Brushless motors

Advantages of a Brushless DC Motor
Brushless DC motors have many advantages over their brushed DC motor counterparts. The most obvious advantage of a brushless motor is its lack of brushes and physical commutator. This difference means that there are many fewer parts that can wear out or break and need to be replaced than in a brushed motor. A BLDC motors tend to be more reliable, last longer, and be more efficient. In fact, BLDC motors have life expectancies of over 10,000 hours.

Another advantage of a brushless motor is that it can operate at speeds above 10,000 rpm in both loaded and unloaded conditions. It is also capable of operating with less noise and electromagnetic interference than a brushed motor because its internal parts are completely enclosed.
