The sensors measure the rotor’s position and send out this data. In a BLDC motor, it happens electronically with the help of transistor switches.Ī BLDC motor controller detects the position of the rotor either by using sensors (for example, a Hall-effect sensor) or sensorlessly. In a BDC motor, this is a mechanical process triggered by a commutator with brushes. The essential difference is in the method of switching the current applied to the wire windings. A similar process takes place in a brushed DC motor. They attract each other with opposite poles and repel each other with the same poles. The rotor’s magnets and stator’s windings provide the rotation of the motor. a stator with windings that create a magnetic field when energized.an armature or rotor made of permanent and in many cases neodymium magnets and.To understand the working principles of the controller, let us start first with the construction of a brushless motor. Working Principles of BLDC Motors and ControllersĪ BLDC motor controller regulates the speed and torque of the motor it can also start, stop, and reverse its rotation. This article will shed light on the characteristics of a brushless DC motor controller, that is how it works, how it is built, and what it works best for. However, there are some conceptual differences in their arrangement and implementation. Nevertheless, it will hardly edge out BDC motors completely as it is still a costly solution with a complex construction and control system.Ī BLDC motor controller can perform the same functions and apply similar methods as a brushed DC motor controller. High performance and durability are among the major advantages of a brushless DC motor. In some fields, they have almost squeezed out brushed DC (BDC) motors. Using electronics instead of a mechanical commutator with brushes was a breakthrough in electrical engineering at that time.īLDC motors have found wide application in various industries - from computer hard drives to electric transport and industrial robots. The implementation of this new type of electrical motor was made possible thanks to a transistor switch invented shortly before.
