Brushless DC motor systems combine compact yet powerful brushless DC motors and high performance drivers to offer excellent energy savings and speed stability as well as a wide speed control range. With brushless DC motors you can downsize your application as the motors have slim bodies and provide high power due to permanent magnets being used in the rotor.

Why is a COB BLDC better?

Without the carbon brushes and copper commutator, the only wear items in a BLDC motor are the bearings.  This makes the BLDC motor far superior when long operating life is required.

Because the windings are stationary and in thermal contact with the outer case, heat is dissipated more easily, allowing for higher power operation in the same package size.  Also, with no brushes and commutator, the overall length is shorter.

Without the mechanical contact of the brushes, higher speeds and peak loads are practical.

Carbon brushes are a design feature from early electric motors. They are still used today as an inexpensive alternative to brushless motors.

In brushed motors, a carbon brush serves as the means to conduct electricity to the rotor. The disadvantage is that friction between the stationary brushes and moving rotor can cause wear and loss of power.

Brushless motors replace the less-durable brush design with an electronic controller. The controller controls which coils in the stator are active, making for an ever-changing magnetic pull.

BLDC motors boast a higher speed range and better torque to speed ratio. They also deliver a higher level of torque relative to their size making them ideal in applications such as power tools.
