What is a DC motor?

A DC motor is a device that converts direct electrical energy into mechanical energy using magnetic fields and electrical currents. The basic construction of a DC motor includes an armature, brushes, and a magnetic field setup.

What are the basic principles of DC motor?

Basic Principles of DC Motor Electromagnetism is the fundamental principle that DC motor relies on to convert electrical energy into mechanical energy. The Lorentz force law, which states that a charged particle moving in a magnetic field experiences a force perpendicular to both the magnetic field and the particle's velocity, is also relevant.

What is dL in a DC motor?

In a DC motor, dL is the length of the conductor carrying charge q. The construction of a DC motor is such that the direction of current through the armature conductor at all instances is perpendicular to the field.

What is a series DC motor?

A series DC motor is a type of motor in which the field is in series with the armature. This means that the same flow of current goes through both the coil and armature. Series motors have a very high starting torque, always rotate in one direction, and their speed is affected by the physical load.

Are DC motors voltage fed?

Most industrial DC motor controllers or drives are voltage fed; that is to say that a voltage is applied, and the current is controlled by measuring the current and adjusting the voltage to give the desired current. This basic arrangement is shown in Figure 3. DC motors exist in other formats.

Why is a DC motor curve drooping?

The slightly drooping characteristic (curve b in Figure 6) has the advantage in many applications of reducing the mechanical effects of shock loading. The series DC motor curve (c in Figure 6) shows that the initial flux increases in proportion to current, falling away due to magnetic saturation.
