Armatures

Armatures are a fundamental component of an electrical motor, functioning as the power-producing element through which current passes. Here’s a detailed description:

• Armatures are constructed from laminations of thin metal plates, typically made of silicon steel to minimize energy losses due to eddy currents.
• These metal plates are stacked together to form poles, which are the magnetic cores around which the armature windings are coiled.
• The windings consist of thin copper wire, wound in coils around each pole. The number of coils and the way they are connected define the performance characteristics of the motor.
• When electricity is fed into the armature windings, it generates a magnetic field that interacts with the magnetic field of the stationary part of the motor (the stator). This interaction creates force on the armature, causing it to rotate.
• The rotation of the armature converts electrical energy into mechanical energy, which then drives the motor's shaft and, ultimately, the machinery or device attached to the motor.
