Ever tried to count how many things around you have electric motor at its heart? The list is endless, starting from your clocks, cars, washing machines, DVD players, vacuum cleaners to hair dryers – most of the electric appliances around us have electric motor inside them. In case your heart is filled with gratitude for its inventor and you want to flip through the pages of the past to know how this miracle machine was invented, read on…Like many other creations, this one was also a result of many brilliant and inquisitive minds. The foundation of this invention was only laid after battery, magnetic fields from the electric currents and electromagnet made their way. Throughout the world, there were many inventors who passionately worked towards developing solutions in the electrical science field.
Brushless motors have much more satisfying results as compared to brushed motors. The basic difference between them is that in a brushless motor, the rotor itself contains the permanent magnets and the electromagnets move to the stator which is quite opposite as seen in a brushed motors. It’s more precise and can also factor the speed of the motor into the equation. This makes brushless motors more efficient. There is no sparking and much less electrical noise. There are no brushes to wear out. With the electromagnets on the stator, they are very easy to cool. You can have a lot of electromagnets on the stator for more precise control. The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor.
