A Brief Description To Help You Understand Brushless DC Motors (Brushed) As Used In Various Electric Car Conversions

What is a Brushless DC (BLDC) Motor?

A Brushless DC (BLDC) Motor is a motor that has electronic commutation (no brushes) and it’s current supply is from a Direct Current (DC) source.

What are the common features of Brushless DC (BLDC) Motors?

Brushless DC (BLDC) Motors have static stator windings and a rotor with permanent magnet(s).

What are some examples of Electric Cars and Electric Vehicles using Brushless DC (BLDC) Motor

Some examples of Electric Car and Electric Vehicles using Brushless DC (BLDC) Motors include, but are not limited to:

What are the advantages of Brushless DC (BLDC) Motors when used in an Electric Car Conversion?

The advantages of Brushless DC (BLDC) Motors when used in an Electric Car Conversion are:

  • No brushes which means no need to replace worn out brushes;
  • Great to use in situations where any spark can cause explosions, since, there are no brushes to arc;
  • Less maintenance than Brushed DC Motors;

 

What are the disadvantages of Brushless DC (BLDC) Motors when used in an Electric Car Conversion?

The disadvantages of Brushless DC (BLDC) Motors when used in an Electric Car Conversion are:

  • Extra cost and complexity of Motor and compatible Controller;
  • Harder to test i.e. You can’t just apply current to the motor and expect it to turn, as it relies on a controller to perform the task of commutation.
