What is DC Motor? A DC motor is an electric motor that runs on direct current power. In an electric motor, the operation is dependent upon simple electromagnetism. A current-carrying conductor generates a magnetic field, when this is then placed in an external magnetic field, it will encounter a force proportional to the current in the conductor and to the strength of the external magnetic field.

DC Motors. DC stands for "direct current," and they were the first type of motors that were commonly used because they could be powered from a pre-existing power distribution system. The speed in a DC motor can be adjusted through the intensity of its current. The current is carried through an armature or stator.

OTHER MOTOR TYPES Compared to brushed DC motors and induction motors, BLDC motors have many advantages and few disadvantages. Brushless motors require less mainte-nance, so they have a longer life compared with brushed DC motors. BLDC motors produce more out-put power per frame size than brushed DC motors and induction motors.

However, DC motors still have many practical applications, such automobile, aircraft, and portable electronics, in speed control applications… An advantage of DC motors is that it is easy to control their speed in a wide diapason.

The construction is same for DC motor and DC generator. Working of DC Machine The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field.

A DC motor is defined as a class of electrical motors that convert direct current electrical energy into mechanical energy. From the above definition, we can conclude that any electric motor that is operated using direct current or DC is called a DC motor. We will understand the DC motor construction and how a DC motor converts the supplied DC ...

A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.

Poster Making DC Motor Construction A DC motor consists of two main components – Stator and Rotor also called as field winding and armature winding. Stator is the stationary part whereas the rotor is the rotating part, and it produces a magnetic field. The main parts used in the construction of a DC motor are the yoke, poles, field winding, commutator, carbon brushes and bearings.

A DC motor contains different parts that understanding each one can assist to know deeply these parts cooperate with each other and in the end how DCs work. These components are: a stator, a rotor, a yoke, poles, armature windings, field windings, commutator, and brushes. Many of its parts are the same as parts of AC motor, but with a little ...
