Brushless DC Motors (BLDC): What Are They & How Do They Work?

What is a Brushless Motor? A brushless DC motor (also known as a BLDC motor or BL motor) is an electronically commuted DC motor which does not have brushes. The controller provides pulses of current to the motor windings which control the speed and torque of the synchronous motor. These types of motors are highly … Read more

Types of DC Motors And Their Applications

A DC motor (direct current motor) has a lot of applications in today’s field of engineering and technology. From electric shavers to automobiles – DC motors are everywhere. To cater to this wide range of applications – different types of DC motors are used depending on the applicaition. The types of DC motor include: Permanent … Read more

DC Shunt Motor: Speed Control, Characteristics & Theory

A DC shunt motor (also known as a shunt wound DC motor) is a type of self-excited DC motor where the field windings are shunted to or are connected in parallel to the armature winding of the motor. Since they are connected in parallel, the armature and field windings are exposed to the same supply … Read more

Series Wound DC Motor or DC Series Motor

A series wound DC motor like in the case of shunt wound DC motor or compound wound DC motor falls under the category of self-excited DC motors, and it gets its name from the fact that the field winding in this case is connected internally in series to the armature winding. Thus the field winding … Read more

Compound Wound DC Motor or DC Compound Motor

A compound wound DC motor (also known as a DC compound motor) is a type of self-excited motor, and is made up of both series the field coils S1 S2 and shunt field coils F1 F2 connected to the armature winding as shown in the figure below. Both the field coils provide for the required … Read more
