5 Questions
What is the main function of a DC motor?
A DC motor converts electrical energy into mechanical energy.
Describe the construction of the armature in a DC motor.
The armature of a DC motor is a cylinder of magnetic laminations that are insulated from one another. It is perpendicular to the axis of the cylinder and rotates on its axis.
What is the role of the field coil in a DC motor?
The field coil of a DC motor is a non-moving part on which winding is wound to produce a magnetic field.
Explain the function of the commutator in a DC motor.
The commutator of a DC motor is a cylindrical structure made of copper segments stacked together but insulated from each other. It helps in reversing the direction of current in the armature windings.
How does a DC motor differ from an AC motor in terms of the input electrical energy?
In a DC motor, the input electrical energy is direct current, while in an AC motor, the input electrical energy is alternating current.
