Application of brushless motor

Release time:2020/11/03

What is the difference between a brushless and brushed motor?

Brushless motors have no mechanical commutation. Brushed motors, the more conventional design, use a mechanical commutation where rotating armatures with brushes are used to make the electrical connections. The reduced moving parts give brushless motors a long life, limited only by wear on ball bearings.


How does a brushless DC motor work?

Conventional DC motors use a stationary magnet with a rotating armature combining the commutation segments and brushes to provide automatic commutation. In comparison, the brushless DC motor is a reversed design: the permanent magnet is rotating whereas the windings are part of the stator and can be energized without requiring a commutator-and-brush system. The commutation of the brushless DC motor is made electronically and can be done either by looking at the back-EMF of the motor or by using a position sensor.

Brushless DC motor applications

Brushless DC motors are integral to many applications, especially those in the Medical Device, Industrial Automation, Aerospace and Defense, Security and Access, and other industries.


Medical: BLDC motors are ideal for high speed surgical and dental hand tools, including small bone and large bone tools and dental tools such as drills. They are also very effective for respirators and ventilators, infusion and insulin pumps, dental imaging, and analyzers.
