What is the main purpose of armature windings in an electric motor?

The armature windings in an electric motor play a crucial role in converting electrical energy into mechanical energy. When electrical current flows through these windings, it generates a magnetic field that interacts with the magnetic field produced by the motor's stator or external magnets. This interaction leads to the development of torque, which causes the rotor to spin and ultimately produces mechanical motion.

The conversion process is fundamental to the operation of electric motors. As the currents change and alternate, the magnetic fields continuously shift, creating rotating motion that harnesses electrical energy for practical work, such as turning a fan, driving a pump, or moving machinery.

Although other components of the motor may have supportive or regulatory roles, the primary function of the armature windings is directly linked to the transformation of electrical energy into mechanical energy, which is essential for the motor's operation.
