Why Brushless Motors Are A Great Choice

Mar 08, 2017

   What Is a Brushless DC Motor?

     Brushless DC motors, also known as BLDC motors, are synchronous electric motors which move around, or are “commutated”, electronically, with DC current powering magnets that move the rotor around within the stator. Instead of brushes and a commutator, BLDC motors use a step motor controller to create the rotation that turns electrical energy into mechanical energy.

Advantages of Brushless Motors

     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.

Brushless Motor Applications

     Any job that uses a brush DC motor can use a brushless DC motor instead. BLDC motors are used in PC cooling fans, DVD players, turntables, and even electric cars. They are also in demand for use in model aircraft because of their ability to provide the necessary power at a low weight. If you’re looking for increased motor efficiency, check to see if you can replace the brush motor you’re currently using in your project with a BLDC motor.
