BLDC versus Brush DC motors

The market is consistently changing. Sometimes that means moving away from a specific product in favor of a lower cost, lower maintenance, and longer lasting option.

Even though the market is moving away from from brushed motors, it’s still important to weigh your options and figure out what’s best for your business. Sinotech has provided a handy reference to help us understand some of the key differences in the motors and figure out what’s best for you and your business.

Brush DC motors have a few specific parts to be aware of. First is the commutator which transfers electric current through the brush assembly to the armature. Brushes ride on the commutator and send electric current to the armature. The armature is the rotating part of the brush DC motor that contains the wire windings. This is the primary motor thats been used for over 100 years.

Brushless DC motors are newer and part of a rapidly growing market. The stator is the outer, non-rotating structure that contains the windings. The rotator is the rotating part of the motor which contains fixed magnets. From 2003 to 2010, the brushless DC motor market grew from 300 million to 1.3 billion, due to the rise of technologies that include robots.
