Thus, a brushed DC motor comprises the following units:Ī stator with windings or permanent magnets Ī commutator, or collectorwith brushes connecting the armature with a DC power supply.

There can also be other components that perform critical functions. The two core components of any DC motor are a stator and an armature, or rotor. For example, an electric vehicle DC motor controller for a brushless DC (BLDC) motor has different design and working principles compared to an industrial DC motor controller of a brushed motor. The specifics of a DC motor controller depend on the motor type ( brushed, brushless, stepper) and functionality of the device that uses this motor. Irrespective of the motor type, this electronic device can fulfill the following functions: The intended use of a motor controller is to manage the performance of an electrical motor. To learn more about a BLDC motor controller, its design, and working principles, you can check a related article on our blog. In this article, we have focused mainly on brushed DC (BDC) motor controllers. In addition, we’ll share our personal experience and brief you on the design and challenges that you can meet while building your own controller. Here, we’ll tell you how a DC motor controller works and how you can use it. In an alternating current (AC) motor, a magnetic field changes polarity on its own.Ī DC motor has some significant advantages, and one of them is the simplicity of its control system. The common feature and the essential condition of all DC motors is the generation of a variable magnetic field that provides their non-stop operation. DC motors have different arrangements and operation peculiarities. Burge, Ph.D., is a senior principal in the Center for National Security and Intelligence at Noblis in Washington, D.C.A direct current (DC) motor is the oldest type of electrical motor that has gained widespread use in a variety of electronic devices and equipment. Wilhelm Burger, Ph.D., is the director of the Digital Media degree programs at the Upper Austria University of Applied Sciences at Hagenberg.
