Direct Current Motor

What is a DC Motor?

A DC motor is a type of electric motor that uses direct current as an energy source. It has two separate parts: the armature and the stator, which are connected by a rotary commutator. This commutator reverses the current between the rotor and the power supply, producing a steady rotational torque. There are two types of DC motors: brushed and brushless. Brushed DC motors apply current to the rotor through brushes, while brushless DC motors use permanent magnets to generate current.

DC motors are easier to install and maintain than AC motors. They are also easier to service than their AC counterparts. In addition, DC motors can easily replace industrial equipment. In contrast, an AC motor may require the entire circuit to be redesigned to accommodate a DC motor.


Types of DC Motors

There are many different types of DC motors. Some are used in homes while others are used in factories. They are used in fans, air conditioning systems, and printers. Some are even used in remote controlled vehicles. In addition, they are used in medical equipment. These are some of the most common applications of DC motors.

DC Motor Working Principle

DC motors work on the principle of electromagnetic induction, which states that a conductor within a magnetic field experiences a force. Permanent magnets and electromagnets are used in both large and small motors. The permanent magnets lose their magnetism during wear and tear, while the electromagnets energize when a current is passed through their core.

Current flowing through the rotor windings develops a magnetic field around the windings, which interacts with the magnetic field of the stator. This interaction generates a force that manifests itself as rotation of the rotor. According to the law of conservation of energy, the force must be opposed, and the back EMF of a DC motor provides opposition to the force.

The armature of the DC motor does not rotate when there is no load applied. When a load is placed on the motor, it starts to rotate, and a large amount of current flows through the armature. This is due to the low resistance of the windings. This causes a counter electromotive force (CEMF) that opposes the applied terminal voltage. This resultant force is called torque. The torque generated by a DC motor is measured in Newton-meters.

A DC motor works by energizing its rotor, which is usually composed of a copper wire wound around an axle. This rotor then rotates in a magnetic field and produces a torque. During this process, electric current is constantly flowing through the windings.

Applications of DC Motors

With the many kinds of DC motors, there is a vast range of uses that can be made use of DC motors.

Each type of motor offers its benefits, generally speaking, there are a variety of applications for an DC motor. At home, smaller DC motors are employed in toys, tools, as well as various household appliances. In retail, the uses of DC motors can be found in conveyors as well as turntables. In an industrial setting, massive DC motors also have brakes and reverse applications.

Here are a few particular uses of DC motors:

  • DC Motors for Fans
  • DC Motors for Pumps
  • DC Motors for Toys
  • DC Motors for Electric Cars
  • DC Motors for Robots
  • DC Motors for Bikes
